For me, the choice wasn't even close. I opted for Silent Running Audio's Craz rack and Ohio Class XL+ isolation platforms, and haven't looked back. IMHO, there's nothing better on the market, and that includes Grand Prix Audio. The secret is that each platform, and each shelf on the rack, is designed specifically for the component it supports. Now that SRA is accepting trade-ins for old platforms, and offer new support pads for the rack shelves FREE OF CHARGE, it's no longer a monetary hassle when you change components. I could've bought any rack out there, and I chose SRA. It's a no-compromise solution--the best of the best, IMO.
