How an audio rack can enhance your amp/pre




Just thought I would share my recent experience with upgrading my sound star technologies rack to the new rhythm rack.

Every now and then, I have a visiting audiophile who really appreciates my system…and traditionally asks – “wow, what makes it sound so good?” My typical answer is it all makes a difference, even down the equipment rack, which can and certainly should be considered a component…but in many cases is overlooked…

Star Sound introduction

About 10 years ago, I was introduced to Star Sound Technologies Sistrum platforms and Audio Points. Audiopoints has always been known for its manufacture of well-designed and beautifully manufactured brass cones used under equipment and as an integral part of an audio stand. This ultimately led to the design of stands designed to transfer vibrations out of components and down to ground. What I didn’t know at the time was how good the Sistrum platforms ‘sounded’. So, I bit the bullet and tried several Sistrum Platforms - what intrigued me about the stands was the design of the Sistrum Platform which allowed a pre-determined pattern of energy, known as Coulomb Friction to develop and dissipate via a high-speed calculated conductive pathway to earth's ground. Which made sense…how do you deal with airborne energy dissipation? I know you could put cones to reduce vibrations from the ‘ground up’ so to speak, but how could you eliminate airborne vibration? We’ve all held our hand on our equipment when music is playing only to feel the equipment vibrate, so how do you deal with it? Draining it quickly to ground made sense, but at the end of the day, all I really wanted to know was…does it improve the sound?

To say I was shocked is an understatement - the Original Sistrum Platforms offered – smoother sound, better transients, dynamics and a lower noise floor. And, the cool part is that you could turn up the sound and the music would flow with greater ease…well worth the investment. Robert at Star Sound was extremely helpful in guiding me through which racks made the most sense for my system.

Rhythm Platforms

Which brings me to 2015…it had been a while since I last spoke with Robert curious as to what his engineering team was up to…which led me to check out the ‘new’ model of Sistrum Stands – the Sistrum Rhythm Platforms.

These new platforms / shelves were substantially heavier, with a nicer overall finish than the original stands, with more grooves allowing for substantially more options to place points in various places under your equipment to refine the sound even further. In addition, the shelves were engineered to deal with resonances in a more efficient manner…The brass cones at the bottom of the rack were substantially bigger in size - 3 inches and quite heavy. The brass cones under the equipment were attached with nicely crafted screws that could be hand tightened and no longer required a screw driver… a nice feature making it both easier to put together but also the amount of tightening could influence the sound. The brass and platform rods are modular, making it easier to put together and painted in a beautiful black finish – in combination with the brass I would say the improvement in the WAF factor is significant – the stands are really impressive to look at. As for structure, these things were a solid as could be – and heavy! Not going anywhere, even in an earthquake!

My system includes VAC equipment, preamp, amps, DAC and a transport. As well as power supplies. Most of which now rested on the new Rhythm Platform.

Listening Impressions:

My first impressions were clearly a lower noise floor with enhanced dynamics, while also being able to hear deeper into the soundstage, which now extended well outside of the speakers. Tempo was faster, due to better-defined, leading edges. The high end was ‘cleaner’, with more sheen and decay on symbols and hi hats. Brass had that right bite to it, without over doing it…Bass lines were tighter which led to better ‘rhythm’ … and best of all, I could crank up the volume and the dynamic range seemed to extend effortlessly, which was a nice surprise.

One thing I noticed, that was true of my initial experience with Sistrum Platforms, is that the newer Rhythm Platforms sounded progressively better after 3 days of ‘settling’ and reached full potential after about 1 week. So some form of break in is required.
Over the years, I’ve tried different racks and various cones under equipment, whether if be soft, hard, ceramic, rubber (or some variation of ‘absorbing material’ etc.) you name it. All of which ‘altered’ the sound, but nothing came close to the Sistrum Stands holistically; while the new Rhythm stands, just take it all to a higher level…
While I cannot expound eloquently on science of Coulomb’s Friction, I can tell you that whatever they are doing at Star Sound visa vie their racks, it works…and it’s not subtle. This is a very audible improvement in your listening experience. If you want your system to perform at its highest level, I would suggest that you maximize your investment in your equipment by letting it do what it does best and put it on a Sistrum rack that will allow it to perform at its best. And if you want the best, I would strongly recommend the Rhythm Platforms.

Agear, Charles,
My rack is DIY with maple shelves, something like a Mapleshade.
I do use SRA Ohio stands under the Lamm amps and Tron Syren, that sits on the rack.
I'm getting SRA rack though.
As I mentioned previously, I've had my whole system on various SS stands at some point, so I have pretty good idea about the product.
So, let me ask you guys- do you really feel, that Sistrum stands are completely neutral and don't emphasize leading edge and don't accentuate some parts of the upper midrange/lower treble spectrum?
It clearly did so in my system.
It's not completely objectionable, and is noticable more on some recordings, and less on the others.
But it is there! And since I'm very sensitive to the issue, I've moved on to more 'benign" solutions.
Again, I can see somebody not to be affected that much, or to be willing to accept the compromise for whatever reason. And that is the whole different story.
What I'm having a problem with, is the fact, that people imply SS is devoid of any sonic signature.
Maril555,
I would have a hard time saying that any audio product is devoid of some level of sonic signature. I do understand and appreciate your experience and impressions. All I can say is is that in regards to my system and individual components the Starsound products have been a significant plus across the board, tonality has been improved in my opinion not hindered. The natural tonal richness and harmonic overtones were revealed in their complexity and beauty. I have little tolerance for added brightness, I do seek improved openness and transparency and this is what I have found with these products. Sometimes equally experienced listeners will simply have different
outcomes and sonic impressions in their respective systems. If I heard the same brightness that you described, I would have quickly gotten rid of these products.
Regards,
Charles,
Maril, what stands did you use and when? SP4s, SP101s? SS products are ideally used on their own without any intervening construct. The products have evolved like everything else.

As for its "sonic signature," its a chicken and egg scenario to some degree. Is it the rack or the equipment? I find my 101s fairly "neutral." What changes mostly is speed, focus or coherency, and ambient data.

Again, if your system is bright or tipped up in character, then SS might not be the answer. For example, some speaker manufacturers rely on wood cabinet resonance for bass and tonality control, and a product that drains that vibration can cause the speaker to sound lean. That being said, I put a vintage pair of Pioneers I bought on Craigslist for $75 as a surrogate while I waited for my speakers to be completed. I put them on a set of "Apprentice stands" which are current generation and smoke the SP4s which I assume u used. I had a speaker designer over who said they sounded better than a lot of 10K speakers he has heard over the years. I have a SOTA system/room where everything change is glaring. Its not a soft, marshmallow sound from the 70s.....:)
If I remember correctly, I had SP-101s under the speakers and power amps, and SP-3s under preamp, CDP
