Krell KRC-3 vs Adcom GFP-750 vs DAC1 Pre


I use an Adcom GFP-750 as a preamp, mostly in passive mode but I will sometimes switch in the active gain stage. In better time I owned a Levinson 380s and liked it a great deal. The adcom reminds me of the 380s. I am considering a Krell KRC-3 to use with my Krell power amp. I am also considering a DAC1 Pre in place of the Adcom and the DacMagic. Please let me know if you feel it either would be a useful step up. I don't need to spend the difference if it won't really gain me anything.

system in stereo mode:
Sony xa9000es
Logitech Duet -> DacMagic via coax
Adcom GFP-750
Krell FPB-600
Infinity Prelude MTS

I use an Onkyo sc885 in the same system for movies.

I have to second the KRC2. I used one for a few years and loved it. Only reason I replaced it was the KCT matched my Krell amp cosmetically & was allegedly better. It was quieter than a church mouse and had a lot more features than the KRC3 I believe. You can look at the Krell website for a copy of the owners manual, it may help you decide. I needed all the inputs it had as well. I couldn’t recommend it enough. I almost wish I had it back instead of the KCT. Almost…
Good luck, John
Thanks for the advice. I have some reservations about the KRC-2 as it doesn't seem to have a HT bypass. I suppose I could build a quality A-B XLR switch or use the record monitor function as a makeshift solution.
Perhaps the TAPE function could be used for the bypass...?
I am not sure, but it seems that I recall that being done.
Good luck, John
