I have many tweaks that worked but these ones that did not:
- expensive feet under amps, CD players and DACs (Unlike under speakers where they have had a big effect, and under the Hi-Fi rack, again a positive effect).
- external clocks
- crystals, anywhere
- raising cables above floor
- gutwire grounding cable (other grounding systems have worked)
- Bass traps
- power conditioners
