Addressing the actual starting point, improved CD data reading, can reduce perceived brightness and very impressively improve listening enjoyment. Beautiful detail resolution and enhanced bass slam are just part of what you will hear. The goal is a relaxed, natural, full range sound which is "all there"
From Herbie's Audio Lab you could try the low cost Super Black hole CD mat to damp microvibations.
From Machina Dynamica a range of modestly priced enhancers is available, most notably Sonic Tonic anti-static spray to label side of CD, Code Turquoise strips to line CD tray of transport mechanism, CD Re-Animator for data surface of CD. Promethean mini-spring isolator supports beneath the CDP/ transport, and under outboard DAC if you later go in that direction.
This type of tweaking is rewarding if you don't mind the little bit of audience participation required to get better sound.
