Rack Recommendations

Salamander Designs might be a place to look. In particular, the Synergy Model 402 for the components you have. Many audio shops carry Salamander so finding a used/demo cabinet is a realistic possibility to save additional $$.

I understand your skepticism, but vibration control is the real deal. You have laid out a lot of cash on your components and would be well rewarded by a scientifically designed stand. I did extensive research and came to SRA Scuttle rack. It is very expensive, but the difference it made was worth it. The backgrounds got way quieter and imagining was greatly enhanced, not subtle by any means, a rock solid improvement, with no audible compromises to my ear. HRS is also very good if not better, but was prohibitively expensive 20K+. another option is to get a solidly built rack and SRA or HRS bases under your key components, Power amp first, then TT.

Tried to post this a few minutes ago, but . . ..

Here's a second vote for the Salamander racks. I have a 5-shelf model for the primary system and a 4-shelf for the secondary. Both racks are on casters - - a huge convenience.

I must give credit where credit is due...Chris at Timbernation built me a beautiful custom rack from scratch to my measurements. He also stained the shelves to match my speakers. Not only does is look great but is incredibly sturdy. As for sound and isolation there is no longer any need for footers or fancy feet just the stock feet. All this for under $1k built to extreme tolerances and easy to assemble.

These racks have come along way from the days of the old Target stands. I am using a variety of the fancy stuff about which you express sketpticism- (Grand Prix Monaco with carbon fiber shelves and all the bells and whistles and HRS, as well as a big shelving platform that was custom made by Finite Elemente back in the day for my turntable)- and not so long ago had Adona, mentioned above, build me a small platform for my phono power supply. They use constrained layer damping for the shelving and platform material; it was relatively inexpensive and for decoupling, I use Stillpoints SS. Very effective. (Even Mike Lavigne, who has one of the uber systems here, is using an Adona stand for his turntable and preamp, unless he has recently changed it out). They make all sorts of stands and platforms to order and aren't terribly expensive- a bit more than you indicated you want to spend but not silly money. You may need to consider additional component isolation beyond what the stands themselves provide but I'd second the vote on that company as a possibly- even with a custom job, they were pretty fast and easy to deal with.
