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.

I don't read any "facts" in this thread. What we have instead is an extremely positive "review" of a product from someone with no Audiogon background followed by a very small number of people repeatedly chiming in with agreement. That's not facts, but simply 3 or 4 people voicing their opinions. Furthermore, when someone disagrees with this limited viewpoint they are met with condescension.

I have not read any condescension in the dissenting opinions regarding rubber. As for "facts" in the realm of audio, they are few and far between strictly speaking. Much of it is driven by intuition and experience. Believe it or not, Starsound has commissioned an outside lab to do measurements of their technology. No rack company has done that to date.

I am consistently surprised how testy people get about this subject (especially when it comes to Sistrum and Starsound). Like it or not but the hobby does evolve and move forward. Look at older magazine reviews of equipment and you see equipment plonked on chairs or the floor. Its akin to the world of cables. "Engineers" cried voodoo for years as they lacked the appropriate measurements tools. Nordost and Vertex have demonstrated changes in jitter performance with cabling using software. The same will most likely be demonstrated with "isolation" technologies, etc....
Wonder how the tone of a string instrument would be affected if a small section of sorbothane was placed on the soundboard and the strings were plucked? Tom
I'm planning ordering more Rhythm Racks next week. The Rhythms I have under my speakers create the most amazing soundstage I've heard. Better than apprentice rack by a wide margin.
I know this because I listen to both racks under my speakers.

To those who comment without hearing stuff... with no experience, all that is left is unfounded opinions of little or no value. no need to comment.
If one is also adding negative judgments without hearing, it usually some empty soul crying out for attention. Perhaps getting a pet would help them feel better.
Some General Rules: when to use squishies as opposed to points:

All audio equipment benefits from damping.

Squishies (ex.: Sorbathane) is useful when vibration is affecting the equipment via the shelf on which the equipment sits. It provides isolation.

Points, such as TipToes or Stillpoints, provide coupling to the shelf or platform on which the equipment sits, and are more useful when the vibration you are trying to control is airborne. Ideally they do not allow vibration to go the other way (they are mechanical diodes). So they are 'sinking' vibration away from the equipment.

So if you have a damping platform you would use a point system to couple your gear to the platform. But the platform might sit on a set of squishies if the shelf it sits on is uncertain.

If you have an equipment stand, generally you would use either points or a platform. Some stands (I use a Sound Anchors stand) have damping properties but you should beware- not all do. Most stereo cabinets (like those from Ikea) and curiously, the Stillpoints equipment stand, have resonant qualities and require decoupling- squishies.

A proper equipment stand with damping properties is usually hard-coupled to the floor using a point system. I use a set of Aurios Pro bearings as they relieve lateral vibrations as well as providing coupling. Prior to their installation I could hear footfalls in the loudspeaker- now they are absent.

These ideas are not new BTW!! My Scully LP mastering lathe was built in the late 1940s and employs a special table equipped with adjustable points for feet. On top of that is perched a damping platform that decouples from the table using a set of squishies. IOW audiophiles did not make this stuff up; its been in use by pro audio for decades longer. So its not bogus or imagination and there are actually rules for their use. If you follow them you will get better results. Wolf isn't nuts and neither are the people riding him.
