I modify/upgrade speaker crossover networks with better parts and was amazed at the sonic improvement. I took this approach when I modified/upgraded my EAD CD-1000 mkIII. I replaced 28 critical caps with much better Rubycon caps, 4 power supply diodes with soft recovery Stealth diodes, replaced all internal wiring with teflon coated silver wiring, and the Auricap tweak right after the IEC inlet.
These are very basic mods/upgrades, I did not alter the circuit design at all, I just put in better quality parts. The results were again amazing. More musical, more air and space around voices and instruments, quieter blacker background, wider soundstage, better imaging, and details within the music were even more noticable. Everything became that much better, highs, mids, and lows.
If you have a decent CDP, it's going to respond well with better parts and is worth it because the source is so important.
