Any experience with HRS Harmonic Resolution system

My only experience is with a friend's system. He had HRS design a long, three section, three tiered rack. This thing is extremely heavy. HRS required the dimension, weight and weight distribution of each component going into the rack so that the shelves could be custom configured for each component.

I can't say what contribution the rack makes to this particular system, sonically speaking, but, I can say I have never seen a more solid and beautifully built rack than this one.

Another friend of mine was the person in charge of assembling the rack. He said he has never put together something with that many pieces that had to interlock where the machining was as perfect as the HRS rack--everything aligned perfectly and was flawlessly machined.

I am all for getting a good rack to isolate the components from the environment and to provide the right structure for the shelves that go under the components.

However, I have found that, with respect to the shelves themselves, there is no easy answer as to what it best. It is not simply the case that the shelf that does the best job of draining/dissipating energy from the component is the best. Some experimentation is required to find what is sonically the best for a particular system and taste. There can be cases where LESS vibration dampening sounds better. This is often the case with source components, such as turntables and CD players.

I heard a demonstration using Symposium shelves under a CD player (Aero Capitole) where one could clearly hear differences between the thinner (cheaper) platforms and the better dampening platforms. It was not always the case that "more" was better.
