Stacking gear no more rack space does it affect sound quality


I've run out of room for my gear. Since I started streaming i have run out of rack space and began stacking. I bought some of those brass disc long ago for putting on top of components for damping and was told by seller not to use to many it will dull sound. Now I have my preamp power supply on top of preamp and dac power supply and dac on top of preamp power supply 3 high. Streamer on top of phono stage. I have another dac on top of streamer. I have 3 racks 2 shelves each between speakers, total six shelves. Do other people do this and does it affect sonics. I don't even have room to take things off to try without stacking, to much crap plugged in.

Contrary to what the obsessed say stacking gear will have no deleterious effect. Why not just buy another rack and rearrange your room to tidy things up?
 
     Power supplies and electronic circuitry, of a necessity, generate RFI/EMI.    That such can interfere with the performance of adjacent electronics; SHOULD be the most basic of one's understanding.    Particularly, if one assumes the position of (imagines themselves) an advice giver!

      Digital gear is especially bad, when it comes to such emissions.

      I have three pieces of my equipment in a vertical cabinet.   The topmost are my TacT preamp and BAT CDP digital noise generators (SS Bass amp and it's massive power supply, below).   On the cabinet's top: my turntable and of course: highly sensitive cartridge and tonearm wiring.

       Those pieces are all separated (the shelves and top completely covered) by Texas Instruments RFI/EMI blocker sheeting.    Something Michael Percy used to sell, but: I believe has since been discontinued.  

        TI does still offer things to mollify the effects, as do a number of others.

         Not everyone will bother with attempting to avoid such interference and: IF the distance between pieces of equipment and wiring can be maximized, it's not as much trouble as the effects drop off, in accordance with the Inverse Square Law.

          That's all some of us silly musical equipment owners have the audacity to call:
                                                              SCIENCE!
If you don’t hear any noise at the listening position when everything is turned on with no music playing and the volume knob at the usual position, then you’re ok.
