Viggen-- I, too, tried plastic cutting boards under my power supplies (pre & cdp). Not as successful as you; tonality and upper & lower extremes went away... strange.
Tonality is the wrong word -- sorry. What I meant to say is that instruments sounded less natural -- slightly "boxy" if you will... maybe related to the highs I lost? Cheers
