slbenz,

you say you have the tubed buffer amps in you system. Do they really work? I was always thinking that, in analog domain, once harm is done it cannot be undone, thus if the CDP produces edgy sound, no stage coming after it could undo that.

But, apparently, my thinking is contradicted by real live (this wouldn't be the first time ).

My CDP is a Music Hall MMF CD-25 to which I replaced the op amps with the Burr Brown OPA-627, the rectifiers with HEXFRED ones and the stock output jacks with high quality ones.

The sound is pretty nice, but I wouldn't mind a smoother one. The amp is a Cambridge Audio Azur 640A.

Do you think a Musical Fidelity buffer amp would be worth the investment? I saw them on eBay numerous times, only I coudln't convince myself to bid on them...
