i owned and really enjoyed a AA Capitole, SE. Obviously you COULD upgrade the unit to SE status, which upgrades the caps and puts in a cryo'd tube. I would not be able to speak for what it would add, since I only ever had the SE version. I also know of someone (user FrankPiet) who had the volume attenuator modded to great effect.
I also agree that power cables and isolation are CRITICAL on any digital front end: I used the HRS iso platform and electraglide epiphany to great effect....
Ultimately, I ended up getting the Reimyo CDP and have not looked back. It's silly expensive and does not have a volume control, so would not meet your criteria. There's always the Meitner separates that do have a built in preamp stage....
OTOH, your stock player is mighty fine - so what specifically do you want to improve on?
