My guess is that your CD player is not up to snuff. No need to seek euphonic colouration if the source and / or DAC are well designed using good quality parts. There are more than a few SS digital front ends ( players and / or DAC's ) that can do what you want without having to swap amps or impliment tubes. If you really like the aesthetics of your Krell, have it modified. For a player like this, i would probably contact Steve Huntley. Sean
