Newbie - Which USED Amp & Preamp for under $2500

LFD integrated is whats happening now or the good old Mac piece will be just fine.Easy to move if they dont move you,good luck,Bob

I agree with the - SPEAKERS FIRST- mantra here. That really decides what all of the upstream gear should be. I have a Magnepan based system, which I love. But that means powerful amps, and then certain types of mellow upstream components (tube pre, mellow turntable/arm/cartridge combo, warmish DAC) to keep the system from being too bright.

One of my audio-geek buddies has B&W 801's and he has all SS gear upstream, Mac 501's and an Bryston Pre. That's to keep his system from getting too warm. With my pre amp in his system, it's muddy, with his preamp in my system it's harsh.

But they each sound great on their own.

That was long winded!! Sorry. Pick your speakers first, then work backwards.

also agree with speaker upgrade first then build system around it

Mmrump, I actually owned the B&W 601 s2 about 5-7 years ago. They were a great value buy. A little shy in the lower mids & bass(as nearly all affordable small monitors are), a tad hard in the high freqs for my taste (I prefer soft dome tweeters), but a surprisingly balanced speaker for that price range. Your 602's have the same configuration & tweeter, except a slightly larger mid-woofer, so the mid-bass/bass is probably a little better.

The collective suggestion to upgrade speakers first makes sense, but I think your B&W's are better than your amp & preamp. By that, I mean you will be better able to accurately evaluate new components through them than you will speakers through that amp & pre. Although, I think the Haflers, run at the low end of their range, may do less sonic damage than the Adcom.

At the price range you are looking at, I'd venture that it's fairly safe to say an Odyssey, McCormack, Belles, or Bryston will perform fairly well with whatever you eventually get speaker-wise. There will be differences in their overall sound, but all are extremely well made and respected designs that withstood the test of time. They are safe bets that hold their resale value, if you find one of them not to your liking. Someone else mentioned Monarchy, their SE-100 deluxe monoblocks are also an amazing value. Well worth considering unless you need a few hundred watts per channel.

Although, I think the performance/sound in preamps varies a lot more than SS amps at that price range.

BTW, are you going to stay with monitor speakers when you upgrade? How big is your room? What type of music you listen to? And how loud?

All those things will help fine tune suggestions for you.

Darkmoebius, Thanks for the advice. I've been keeping my eye out for the amps you mentioned and I don't think I would hesitate to get one if the price was right.
Based on the feedback here, I've started a search for speakers simply to get a holistic view of what I want. To answer your questions, the room is 17X13 however it has a large opening (9ft) to a dining room. I listed to jazz, 60's psychedelic, hip-hop, ambient, pop and electronic. All of my music is digital. On occasion i will push them quite hard and wake up the neighbors. I don't have space to place them out 2-3 feet from a wall, and as a result, someone recommended the Paradigm studio 60's or 100's. I can't do stands because I have a small child.
