The topic of loudspeaker design elicits strong opinions. From the manufacturing companies, to dealerships, to customers, most folks have a view about what designs are optimal and which designs are flawed.

In all fairness, defining the underlying causes of not so great sound quality is often blamed on loudspeakers. In some cases it is a fair accusation, because some loudspeakers do sound bad, no matter what they are hooked to or how they are placed in a room. This is very few speakers though. The real cause of bad to mediocre sound is a combination of many parts in a stereo system, each with their own contribution to the sound for better or worse.

For example, power cords are the starting point for good and bad sound. I know, I know, power cords can’t possibly make a difference, right? Well, they do make a sonic difference and if you have never had he opportunity to hear a good power cord, you should seek a known good cord. And just in case you are worried that a good power cable is too expensive, rest easy. Some are around $100. We suggest trying the Shunyata Research Venom power cord to get started. A nice upgrade over a stock cord. From the power cable at the wall to all the power cables for each component, power cables can degrade the sound of what would be a very good system, when equipped with good AC cables.

The interconnects are as important as the AC cables, with more influence on the sound than most people realize. Some customers have used a certain type or brand most of their lives, being told by a dealership that they are the best cables to use. In very few cases, the cables will be matched up well with the system and loudspeakers being driven. In many systems, a better sounding interconnect cable and loudspeaker cable set could be used, taking a mediocre sounding system to world class sound. Preposterous claim, but again, please try some good cables before falling victim to the “wire is wire” philosophy.

As loudspeakers are the last piece of equipment connected to the system, they have an opportunity to add a large amount of distortation. Changing electrical energy into physical sound energy is hard work! Our philosophy at Aluminous Audio is unique in several ways and defies most of the trends in loudspeakers today. We do this to avoid distortions that plague most loudspeakers.

Our designs avoid pitfalls that most large floorstanding speakers cannot escape. One of the major pitfalls has to do with time alignment of low frequency drivers with middle and high frequency drivers. There is only one way to integrate the low frequency sounds with the middles and highs. That is active electronics AND proper placement of the low frequency drivers within the room. A passive low range driver cannot properly align itself in terms of absolute phase with the middle and high drivers, and simultaneously be placed within the listening room to avoid creating massive standing waves, dips, and cancellations. More on room acoustics in another post. In all cases, the additional benefit of physically separate and self powered low frequency drivers is the ability to choose from a much wider range of amplifiers to drive the monitors/main speakers. A sweet deal and you will not need to set aside additional money to pay the increased electrical bill from running a monster powered amplifier.

Audio Shows - Where Do We Go From Here?

Here we are in 2019. If you are like we are, planning what shows to attend is part of your travel budget. There are the well known shows such as AXPONA and the RMAF show. AXPONA is a huge show and boasts relatively good sound from a hotel room. RMAF will be in a brand new location for 2019, which is a good move in our opinion. The old RMAF location was overdue for a move. Not to mention the location was more than 30 minutes away from the airport.

So what do you want to see for 2019? We would like to see the continued growth of AXPONA, and have it become a solid competitor to the Munich high end show. For small and medium size manufacturers such as us, we would like to see AXPONA be the primary worldwide show in the near future. Why? Because Munich is far too costly for any small company to attend. Additionally, the Munich show is really a industry show that serves distribution companies and dealerships. Small companies such as ours that do not use distribution and generally do not work with dealerships have no reason to exhibit at a show such the the Hi End Munich show. Our showroom at our location is our primary location for customers to visit and listen, and our loudspeakers end up in their own home after that!

New Amplifier, First Watt F7, With Commentary


We have been listening to the First Watt F7 for several months now. During this time we have put some serious thought into this blog entry. To begin with, we wanted to cast aside any bias about what an amplifier should sound like. Instead, we focused entirely on our emotional connection to the music while using this specific amplifier.

First things first, is a thank you to our friends and kind people at Pass Labs and First Watt for making this amplifier demonstration possible. We are totally impressed with their business culture and their generosity to make such a product review possible, Thanks especially to Desmond Harrington.

On to the review commentary. When you open the shipping box, you get the impression that this amplifier is built with purpose. What was not in the box, which was refreshing, was a bunch of hyped up reviews. Why is that refreshing you may ask? Well, speaking from our perspective, there are too few UNBIASED reviews of products out there. Money gets in the way too often and one is hard pressed to get a straight answer from anyone with a question such as “is this product the best I can purchase for X dollars?”


Our process with listening to gear is really simple. KISS. Remove the exisiting component, replace with new component for review, and listen for several months. No talk about “removed my personal reference, Brand XYZ.” Talk about showing your hand as biased before listening to new equipment!

Next is the part where we diverge from most reviewers. With this amplifier, we listened to all kinds of music. Good recordings, mediocre recordings, and bad ones. What we are listening for is the emotional connection to the recording and a general sense of completeness to the music. The whole experience is allowed to just be itself. This is the most important aspect because without the ability to cast aside our biases, an objective review is nearly impossible. At the end, we can try to convey what the listening experience felt like for us.

From the first minute of listening with the FirstWatt F7, it was obvious that the design was focused on sound quality. Of course the casework is attractive yet without frills, but with the F7 it’s the inside that really counts. A class A amplifier rated for 30 watts, the F7 was driving our own GRAVITAS monitors rated at 87db sensitivity and a pair of self powered GRAVITAS subwoofers. Did the F7 have the power to drive 87db 2-way monitors effectively? Yes, without using any preamplifier or linestage gain, just directly from digital streaming. Also, there was no alteration of the sound from preamplification of any kind. The takeaway from the setup was the F7 had a sense of fullness to the sound. Let me explain.

About 83db to as high as 87db is comfortable listening for many folks, same opinion here from us. The F7 playing music at 83db offers a complete soundstage and a well defined image. There was no urge to go higher in volume, as it was totally unnecessary. Louder was not fuller, it was just louder. This capability of the F7 is likely to mean it plays well with a wide range of loudspeakers as it has the ability to control the drivers well, even at LOWER listening levels. This affords the F7 to deliver the musical magic right from the get go.

Another observation of the listening sensation from the F7 was musical honesty. WIth good recordings the acoustic space was very present. The vocals and instruments were natural and clearly defined in the space. These moments of listening to a good system are the moments that keep us loving the time machine that is available with well recorded music. Hearing the emotional intent of the lyrics set to music by the artist is really addicting. For us, it is fuel for searching out more artists and having that same emotionally connected moment in time through the magic of our home stereo setup. The F7 was the heart of the system to provide the listening experience of a convincing portrayal of the past musical event.

So what are the F7’s weaknesses? Very few, and minor. Perhaps total saturation of color to the images was less than we have heard with a few more raw power amplifiers. This was only noticeable with familiar music, and even so the difference was so small it was difficult to detect. One other possible weakness could be a small degree of warmth, but that is up for debate. Is the small amount of warmth a result of the F7, or is it simply the generous amount of undertones and overtones that could now be heard by using the F7? We don’t know but it is food for thought.

Where does the F7 really shine? Difficult to pick just a few areas as it did many things so very right. Acoustic recordings were stunning. Electronic recordings were equally stunning, with the exception of poorly engineered mixing with overly processed sound. Many instruments could be heard radiating their natural beauty just as they exhibit in real life. Steinway pianos, acoustic guitars, trumpets and upright bass and many more. All sounding as though they are parked in the room with you.

The F7 can be summarized as a class A design that is an example of what class A is all about. Realism, texture, depth, and a huge soundstage. Delicate and detialed with ample power, The 30W output rating is likely part of why this amplifier sounds so good! If you have never tried a class A amplifier the F7 needs to be on your list of amplifiers. We loved it and would be happy to discuss the experience in greater detail with anyone. Send us an email if you want to chat! Take care audio friends!


We are happy to announce a new amplifier to arrive in our listening room. We have enjoyed the sound of amplifiers from Pass Labs in previous setups, so we thought let’s try something out of the ordinary.

We will be unboxing and setting up a FirstWatt F7 amplifier. Interesting, a $3,000 amplifier driving $48,000 loudspeakers. Why? To prove a point for any audio enthusiast. Small monitors, with a pair of self powered subwoofers, all being driven by a SONICALLY excellent amplifier such as the FirstWatt. The GRAVITAS monitors are 87db sensitivity, which is no problem for the FirstWatt. Massive power is not required for great sound, in fact it may hinder great sound in this mini monitor and powered subwoofer arrangement.

Unboxing and listening review comments to follow. Want to hear it for yourself? Book an appointment with us by email. LUKE@ALUMINOUSAUDIO.COM

What amplifier do I need?

The topic of amplifiers is fascinating and all too frequently misunderstood area in the world of performance audio. The misunderstandings and resulting false conclusions are the result of many factors. You have likely heard the usual stereotypes about amplifiers such as:

-Solid state amplifiers are required for high power and difficult to drive loudspeakers

-Solid state amplifier are less expensive

-Solid state amplifiers have the best sounding bass

-Tube amplifiers always make systems sound better

-Tube amplifiers add distortion that makes the sound "warmer"

-Tube amplifiers are "more musical"

The list could go on and on, with all of these stereotyping statements being false in one way or another. Truth be told, amplifiers and their operating designs, are extremely complex and cannot possibly be categorized into two simple groups of tubes vs solid state. Here's why.

The design and the resulting sound quality of an amplifier, is influnced by many factors. Overall topology and layout of the design, type of parts used, and the quality of parts used play a major role in creating the sound quality from an amplifier. Amplifiers from either the solid state or tube amplifier categories have the potential to be designed really well or not so well. We will not get into the design and engineering aspects here of what makes amplifiers sound good or not so good, but let is suffice to say that not all amplifiers are created equal. Which brings us back to the title of this entry, what amplifier do I need?

The best thing you can do is ask around and do some research. A word of warning however. Many internet forums are filled with strong opinions that are not well supported with facts, With that out of the way, you may wish to call a dealership near you for advice on amplifiers to try, or give a call to a retailer with great service such as The Needle Doctor. After you have spoken with several sources about amplifiers to try with your system, find a way to audition the amplifier in your system at home. 

This short article is meant to open your awareness to the world of amplifiers and avoid falling victim to stereotypes that lead you towards the purchase of an amplifier that is not ideal for your system. The best advice would be to keep an open mind and try a variety of amplifiers before making a decision. If you have never tried tube amplifiers or never tried solid state, there are numerous choices that can take your system to another level of enjoyment.

Our listening experiences with GRAVITAS loudspeakers allowed the opportunity to try a wide variety of amplifiers, both tube powered amps and solid state. We have experienced excellent results with these amplifiers:

-Constellation (solid state)

-BAT (solid state and tubes)

-Pass Labs (solid state)

-Aesthetix (tubes)

-Ayon (tubes)

We will cover the topic of amplifiers in the next blog entry with more details about what makes for a great amplifier. In the meantime, try out some amplifiers in your system and hear the results. Send us an email with your findings! We love to talk audio. 







speaker cables, power cables and interconnects - do they matter?


Do all wires sound alike?

This question comes up frequently for high end audio manufacturers and customers. The primary thing I see out there in forums is two distinct groups of thought. One group is certain, often times without doing any listening comparisons, that wire and cable cannot possibly make any difference. They support their conclusion with comments such as "the electricity came from the power station and miles of wire, how could any wire make a difference at your stereo's location?" The other group of people are what could be called experimental. These people are willing to try products and listen for any differences. 

My personal experiences with this topic come from the research side in designing our state of the art GRAVITAS loudspeakers. Some of the approach was studying the success of other speaker designs and improving upon already known principles. Our primary area of research and testing was experimental. And I mean really experimental. I won't cover everything we tried as it would be a novel in length. Just a few highlights to share right now. In part of our testing, we changed the internal wiring for the monitors. The differences in sound were not minor. Some wire sounded OK. Some was hashy, bright, or flat sounding. Expensive wire did not necessarily sound better, and we tried some high cost wire. In the end, we found a wire that sounded wonderful with our monitors. So how did we find the right wire? Through listening tests. Could we have looked at specification sheets of the wire looking at resistance, capacitance, amps delivery, and so on? We could have, but it would have been boring and offered no help in choosing the best sounding wire for the application. 

Another test involved using high end power cords for our powered GRAVITAS subwoofers. Here's an area where one camp would say "bass is bass. It cannot sound different with different amplifiers, and there is no way a power cord will change the sound." Our testing here was the same method as the internal wire tests. We tried a variety of cords from manufacturers. We would listen to a track, change cords, and listen to the same track again. The results were easy to hear. Stock cords and some aftermarket cords sounded OK. Other cords sounded significantly better. Why is this? There are technical reasons why, but ultimately who cares about WHY it sounds better. It sounded better. 

If I could leave you with one message on this subject, it would be this. Please try products in a system good enough to perceive audible differences that cables and wire produce. I guarantee you will hear differences. In fact, this area is a primary way to improve any system, no matter the current level of performance. A little willingness to experiment can yield dramatic improvements. But of course, if you subscribe to the "wire is wire" camp, you just read this article to hear about something you already know everything about! Ha. This stuff is supposed to be fun and allow for the pleasurable music on your terms. Until next time, enjoy your system and happy listening.

Secrets of Sound Quality - Speaker Placment

Is there a boilerplate, mathematical formula to place speakers optimally in a room? In my experience, the answer is a definitive NO. Don't take my opinion only on this topic, as you will find some of the best dealerships in the country have a dedicated person for loudspeaker setup in customer's homes. Not all of them will tune by ear, but those with the most experience and best results often tune by ear. If you would like some references to contact, give us a call and we can name some dealerships we like to work with.

Not to worry, there is a way to place speakers optimally. The required equipment is your own ears, and some patience. This article will equip you with a basic process to repeat our setup process for loudspeakers, and reveal one of the lesser known secrets of great sound. Here's the best part. Every system can benefit from better speaker placement and the only cost is your time to complete the process. 

So what about the secret part. It's not really a secret. It is more the fact that all too often, speakers are set up in a room with a that's good enough attitude. When the placement of the loudspeakers is taken more seriously, tuned by ear and made to work cooperatively with the room, the sound takes on a magically effortless quality. Really beautiful sound that is enjoyable for hours at a time. Intriguing idea, especially if you have never heard a system set up this way. Once you hear the results in your own system, it will shift your idea of what is possible for stereo system performance. So for now, put aside any biases and give this setup technique a try.

A quick note about those claiming mathematical techniques for speaker placement. Overall, there is plenty of incorrect information on the internet about optimal speaker placement. Postings abound in audio forums, and amazingly every poster feels their technique is the correct and only way to achieve optimal performance. I am sure you have read such statements as "my speakers are exactly 2 feet from the front wall, at an angle of 37 degrees toe in, with the listening position equidistant from the triangle formed..." Blah blah blah. So let's begin by putting to rest the notion of mathematical speaker placement for your room. And here's why. Almost no two rooms yield exactly the same acoustics in their response to sound sources such as loudspeakers. Furniture and items within the room have a dramatic effect on room acoustics as well. Bottom line is this. Every room is a little different. What to do? Fortunately, the answer is found in your head. Well, actually, on your head. That is in the form of your ears. To allow your speakers to work optimally with your room, the process is pretty straightforward. Without giving an overly detailed description of the process, it can be distilled into set of two steps.

1) Disconnect either the left of right speaker cables from the amplifier. Using the speaker that remains connected, choose any song with a well recorded voice and clear bass notes. Some strings and high frequency is needed as well. Norah Jones songs work well, but choose anything you like. Set the volume relatively loud, almost uncomfortably loud, and have the speaker up against the wall. In very small increments, begin moving the speaker away from the wall. Take your time doing this, as you will need to return to the listening seat after each small move of the speaker. Patience is key here. At certain locations, the sound will be fairly unpleasant. Shrill, overly boomy, muffled. Just plain awful sounding. Continue moving in small increments until you hear a more balanced and clear sound. When you hear this, mark the location of the speaker with masking tape on the floor. Continue with this process until you have found 3 to 5 locations that all sound balanced and pleasing. Choose from one of the locations market. Don't worry, any of the marked locations will work equally well. You will know it when you find it. It will just sound right. As the final step, without moving the speaker very much forward or backward from its taped, great sounding location, toe in the speaker just enough to have the singer's voice be somewhat in the middle of the soundstage. Don't worry about getting the voice exactly in the middle. The final tuning will be complete when the other speaker is placed in step 2.

2) Leave the speaker in place that has been "set", and leave it plugged in. Repeat the process with the other speaker. After the second speaker location is placed using masking tape and listening method, toe in the speaker just enough to create a defined location of the singer's voice. Use caution here, as not all recordings place the singer's voice in the middle of the soundstage. Use a couple different tracks, or perhaps a song that has a known center location of the singer's voice.

That's it! By placing your loudspeakers with this method, your system will be optimized to your room. In numerous cases for rooms I have personally tuned, excellent results have been achieved without the use of ANY room treatments. Many would claim this to be impossible, but it is simply not so. I encourage you to give it a try. With the money saved from not buying a room fill of diffusion or absorption panels, you can purchase some nice art work for the room.  

In all seriousness, if you have questions or would like help, please reach out by email. We are happy to help and love to have customers discover their system can sound much better, and all it takes is some patience and a set of ears! Happy listening.
