Preamp to pair with my Adcom?

I would more refined, although warmer might apply as well. The highs are a little harsh at times. But I don't want them to be muted.

Reed, the best thing I ever did in the world of audio was ditch my Adcom power and pre amps. In the years I had them I hardly if ever sat down and did dedicated listening, it was always as music in the bakground. When I had the $$ to do something about it I did. With my new amp and pre, I hardly ever DON'T sit down and listen intently.

Readthis, the ARC preamps I suggested will make the GFA-555 more transparent and closer to three dimensional. Will also extend the treble but it will be more refined (alot less noticable grain) & pull more detail from your recordings. Either the LS-1 or LS-2 are relatively inexpensive compared to other ARC preamps and are hybrid. They use only one triode tube with mosfet followers & are not considered to be very warm sounding but lean more towards accuracy. This suggestion is based on the idea you intend on keeping the GFA-555 to save a few dollars as there are better amps like the McCormacks.

Okay, thanks for your help, guys. For now I'll keep running the CDP directly into the power amp until I decide on the best preamp option, or to replace all the Adcom stuff.
