Take a look at the pics of James' listening rooms. The Bryston gear is always on good supports.
The good racks and good platforms are dangerous things to be exposed to. Prior to exposure the need for them just isn't apparent. Once tried though they can't be lived without. My speakers are 94dB and go from 15Hz to 100kHz powered by 220wpc and augmented by a pair of built in 1kW subwoofer amps so I guess I need more vibration isolation than most. I started with DIY multilayers with vibrapods, acrylic, granite and spikes and went up to Critical Mass Systems platforms and racks. I found them so indispensable that I picked up the line eventually because one client with the same speakers borrowed my CMS GM amp platforms and lent me his in return then insisted he buy mine from me because he too couldn't part with them. Well the customer is always right and I figured I owed him that much after buying luxury car priced speakers from me. I've since gone all CMS. These racks and platforms cost a fortune. Double the price of the Isis but I have had one Isis owner switch over to CMS just as my client switched from all GPA to CMS. For the record I had mine even before the reviews in PFO and Stereophile came out.
I'd say the closest competitor is SRA which is also very good and in the indispensable category. They are also priced similarly. I went with CMS over SRA because with SRA each platform is designed for the weight of the piece of equipment that's to be put on them. The same goes for GPA. CMS is more flexible in that they accommodate a wide range of weights as well as weight distribution which is an issue particularly with tube amps where the bulk of the weight is where the OPTS are located. The racks are also modular so you can go from amp stand to 5 shelves high and anywhere in between.
In shows where manufacturers try to do their best for obvious reasons, you'll see them used by Jeff Rowland, ASR, Lamm, VAC, BAT and many more with products ranging from $5,000 to $140,000. No reason why they shouldn't work just as well with Bryston electronics. Especially since I've never heard a Bryston based system that can be described as "wimpy". Bryston gear is more often than not matched with full range, high output speakers. Such systems almost always benefit from more robust vibration isolation. In fact James might want to give them a crack.
Okay so I sound like I'm pitching so I'll stop now. A bit of a disclaimer though because I am half way around the world and won't benefit from a single penny as you folks are way outside my allowed sales area. It's just that I am so satisfied with mine I just felt I should share that.
