HRS M3 vs Symposium Ultra platform

Hi Larry
I agree with what your saying especially "It is easy to get caught up in certain obvious improvements, like greater clarity and resolution of detail, and end up losing something else that is harder to quantify or explicitly recognize ("musicality" or repose and grace)."

I would suggest that the HRS does not have a sonic signature. It does not tip the top end to create hyperdetail. It does not add warmth to the midrange. It does not lower the bass. It simply removes component generated vibrations so you hear your equipment. Whatever you put on it, you will get more.

Many products remove certain vibrations but not all. This results in a sonic coloration. Whether you talk about a shelf, footer, or rack, most will do some things. And many of those things are sonically fine. If you need to speed-up the sound, or slow-down the sound, then this can be accomplished at many price points. The HRS just results in a purity and clarity, IMO. It may not hit you over the head on a brief audition, but I think it is the foundation of a long-term satisfying system.

I would suggest you try an HRS platform when one comes-up used. If you don't hear a difference, you could probably sell for very little loss. Consider supplementing with the HRS nimbus footers as well and allow some time to allow your ears to adjust to what it does.

The HRS is far superior to the SU stuff. I had both. If you want one of best get the HRS.

RTN has it right.
