Didn't actually BUY, but got in for free today from Salamander Designs a complete set of 8 of their rubber isolator "washers", 8 of the steel washers, and 8 of the hex nuts. I had e-mailed them telling them I wanted to buy them to add a shelf to my Salamander Designs Archetype 3.0 stand, a shelf I already owned.
They took almost a week to reply, but when they did they simply asked for my mailing address and said they'd send them, gratis. A week later, I got them and now have 4 shelves on the 28" tall rack.
On top, my E.A.T. C-major turntable (Ortofon Quintet Blue m/c cartridge.) Second shelf, my $200 Emotiva USP-1 pre-amp. Third shelf is my Bluesound Vault 2 and Schiit Mani phono amp. Bottom shelf is my $100 Carver M-1.5t power amp. It's a "2-channel Frankensystem" of new somewhat expensive stuff (the E.A.T. turntable and KEF Reference 1 speakers), combined with "budget oriented" pieces. Sounds incredible though, primarily because of the speakers, lots of headroom on the amp, and incredibly good acoustics in the room.
Yeah, it was a quick toss it together. I'll do wire management this coming weekend.
