Preramp for Adcom GFA 565's

That's the combo I had about 17 years ago, running into Martin Logan Aerius speakers. It was pretty good. If you are looking for another option and products based on the same time frame, you could also consider a Melos preamp (SHA 1 or Gold). These are really nice preamps for the price you can get them for and make wonderful headphone amps to boot. I think the Adcom/Adcom combo can get a little bit brite (depending on your speakers). But overall, I think that (Noble100s) approach is worth trying for you.

Dsper,

Ckoffend makes a good point in suggesting that the Adcom GFP565 preamp and Adcom GFA565 monoblocks combo may be a bit bright, especially with a digital source.
That was my experience when I used the Adcom preamp with an Aragon 4004 solid atate amp. I solved this issue by switching to a tubed preamp (VTL 2.5). So, the Melos preamp that Ckoffend reccomended or a tubed preamp may be a better solution for you, depending on your sound preferences.

However, my offer still stands (atleast for a week or 2) in case you decide to give the Adcom a try. Good luck in your search.

The VTL is a good recommendation. Other tube preamps that you should be able to get for a good price (and with good reputations for performance) that you might also consider would be any of the following:
ARC (Audio Research) LS7 (and others I am sure, but I once owned the LS7 and as a result I know that would work well).
Golden Tube audio SEP 1 (I think that's the model number. I never owned one, but did own a couple of their amps SE-40s running in mono. Good equipment).
Sonic Frontiers Line 1,2, or 3 (depending on budget)

Thank you for the good suggestions.

This is hard - I keep thinking of reasonas to not pull the trigger on the amps.

Am I nuts for wanting to move to the Adcoms from a new Krell S300i? I would be picking up another 150wpc into 4 ohms, and a lower noise floor.

Dsper,

What speakers will you be using? I think the Adcom monoblocks would drive almost any speakers easily enough but they may be overkill for some. Thanks
