Distortion from Audio Rack ??


I've appreciated good sound for many years but only recently have I been willing to invest the money needed to create a system I loved.  Granted, it's at the low end of high-end, but it is my high end :-).

Current system:  Advanced Paris A12 amp, EverySolo A10 streamer/DAC, Furman Elite 15 PFi power conditioner, Warfdale Elysian II speakers, SVS SB 1000 Pro sub, all cabling - Cardas Clear Reflection.  Room size - 24' x 14'.  Sounds amazing!  Sub will likely be upgraded within the next year.

The issue - my audio system is housed in a large wall unit made back in the mid 80s.  There is open cabinet space originally intended for either audio or TV.  Dimensions of available cabinet space - 23" H x 30" W.  My solution for housing the electronics was to purchase a Riveco 9U Rack with Reinforced Top.  I purchased a separate mid-level shelf connected at all four corners.  I also placed Pangea Audio Mega Feet under the rack.

I've read a lot on different forums about the impact of surrounding metal, vibration etc. on quality of audio sound.  My system sounds excellent and I have no complaints about "perceived" distortion.  But I also know from my own experience of upgrading cables that it's difficult to anticipate the degree of improvement one might find until you actually find it.  

So my question - do folks see the rack is problematic?  And besides getting rid of beautiful cherry wood wall unit, are there additional solutions within reach that don't entail a major restructuring in the placement of my electronics?

I was to show the following links and explain the Support Footers for heavy items where the 616 is usable is as a good as any designs out there and can be found if searching out for cheaper than shown in the Link/

Hooters for equipment will not be bettered for the monies and these are available in abundant numbers.

Equipment Footers can be used with methods proposed by Barry Diament, which are heavily copied since their being presented as a design.  

I had some speakers on some homemade stands for a few years.  They had a fairly large flat wood surface.  I switched them out for some stands that had minimal surface area.  I was very surprised at how big of a difference it made.  I speculate that the woofers caused the big flat area to resonate and blur transients.  I also remember decades ago making tons of damping doodads and being surprised how obvious the sound of the case of my amp vibrating was when I clapped.  It was way more substantial than the sound of any electronic distortion.

@russf1  If you are willing to spend the money on IsoAcoustics then I’d suggest you get Stack Audio AUVA Eq’s for about the same money. They are far better than the Orea, I’ve replaced all of them (Orea) with the AUVA EQ’s. The improvement was unexpected for such a simple and inexpensive tweak. In most cases you can use 3 for each component, I use mostly 1’s and 2’s They are based on the weight of the supported component.

" Hooters for equipment " surprise

21 Hours without sleep, Footers for equipment should be a better place to start.

I've been digesting advise from this discussion. Stack Audio AUVA Eq sounds like a winner.

In addition to the component vibration dampeners I've been re-thinking my audio rack.  I am limited with space (23" vertically), and that creates some challenges. 

One high quality brand is SolidSteel Hyperspike Series, but they are quite expensive.

I have found a similar version made in Taiwan - about half the price, though of course it could also be half the quality.

Has anyone had experience with this product?
