An audio rack that really does make a difference.

Symposium Acoustics is an outstanding product line.  I have been using their Rollerblock Jr+ devices along with the Segue ISO for my turntable and it made a significant and very positive difference in SQ, particularly for mid-bass, bass, and overall definition of instruments in those frequency ranges.

I recently upgraded to the Symposium Foundation Rack Ultra.  At the same time I added additional Rollerblock HDSE devices for my preamp, amp, and phono stage.  This is not just a rack, it's a vibration control system for all of your components.  The synergistic qualities of this design/concept is nothing short of phenomenal.  The Foundation Rack Ultra provides the top level with an Ultra platform which is best if you have a turntable or even for placing a digital source unit (SACD player).  This product is the real deal and fits right in your budget.  Contact the owner, Peter, to discuss your needs.  He is very knowledgeable, easy to talk to, and will steer you right.  I suggest that you begin by studying their website first as that will provide you with some insight prior to discussing with Peter.  Best to you.

Another vote for Core Audio Designs - plyKraft rack. If wood is your thing...there isn’t anything I’ve seen that can match the craftsmanship and smart engineering of plyKraft. They are not your garden variety wooden racks. 

Thanks everyone for your feedback. I want to address a couple of
responses. I’m quite aware of what negative effects occur with the rack in the middle, between the speakers. Unfortunately I suspect,
like myself, most don’t have the space or the the means to place it off to the side.

It is the single biggest killer of sound staging and depth perspective, it makes a hiend sound into midfi, because there's no artist to place and see with your eyes.
If you can't go to the side, maybe the behind you, or as I did in one place that allowed it, the next room.
