Silent Running Audio vs Harmonic Resolution System

Both are typical "High End" Products but a painted piece of wood can look important....

What are you guys talking about? Are these the best answers you two can
come up with? :) I take it that you are speaking empirically, right?

Saint- I think Myles Astor used the SRA; you might write to him- on the HRS, there must be some folks who use their big rack in their systems, based on a search you could write to them. You are thinking about this stuff for your Lamm gear and digital front end? I have a large HRS platform under my turntable, but it is less about isolation and more about having a large, stable platform to hold a heavy, high mass table and arm set-up that has no plinth of its own.
When I had the L2 line stage, I used Grand Prix Monaco as a rack, and used various things to damp the resonance of the chassis, including the small HRS 'plates.' You might also look at what a number of people are doing to bypass fancy 'isolation' racks and use simpler heavy duty shelving or platforms (not even 'audiophile approved'), along with free standing (not tied to a rack) decouplers like Stillpoints. But, you have to experiment. The Stillpoints and other decouplers, while effective, are not a panacea- any of these things that are effective also change the tone and character of the sound. Good luck.

Having heard various racks and shelves under components, I would say that any choice is somewhat of a crapshoot. Greater degrees of isolation and absorption of vibration is the goal of these products. But, from a sonic preference perspective, "more" is not necessarily better. I heard a Symposium demonstration with an Aero Capitole CD player many years ago, where the player was put on progressively "better" platforms in the Symposium line. The sound from the player on the best platform was WAY too lean and analytical.

I have heard a bit of the same with different platforms under linestages and amps as well, though the results were less dramatic than what I heard with the CD player.

I know someone with a custom designed top end HRS rack and amp stands. I have never seen a rack that is more massive, solid and impecably constructed (VERY tight machining tolerances). There is absolutely no movement at all in the rack no matter how hard one could try to move it. As for the sound, I can only say that the system sounded great, but, I have no idea what contribution the stand makes and whether it could have sounded better with something else (I cannot think of another stand which would have looked better). The BIG downside of this HRS system is that it cost more than most people would spend on an entire system.

Hi Whart,

Thanks for the insight. Yes, I am thinking about a rack for my gear and digital front end, but not the Lamm monos. The Lamm Preamp, the Sooloos Ensemble, the Meitner MA-1, and a cable box. How do you like your HRS platform under ur turntable? I owned a four shelf Grand Prix Monaco rack too. I sold it to finance dome upgrades. Two of reasons I sold it were, 1. I learned that the sorbothane pads lost their effectiveness to mitigate vibration over time (which, in turn, meant I had to unload the rack to change out the pads periodically) and, 2. that post in the rear was making life difficult for cable management. I'd really like a rack that I could use from this point forward without having to maintenance it. And when you're spending all this money, why should you have to?
