Newbie - Which USED Amp & Preamp for under $2500

My preamp has seen better days and is sounding awful. My amp is pretty weak too. I have $2500 to spend and I need help. I've been looking at the following, any advice would help:

Audio Research SP17L Tube Preamp
Quad QC24
Arcam c30

Arcam PI monoblocks
Conrad Johnson MF 2250
Bel Canto Evo 200.2
Quad 99
Perraux 200P
Refurbished McCormack DNA 125

Below is my current setup. I plan on upgrading my speakers in the near future, so I'll want something that will work now and later:

Hafler 9130 amp (x2)
Adcom GTP 500 Preamp
B&W 602 series 3 Speakers

At your price point, I would seriously consider(used)...

Modwright swl 9.0 se ($1k-$1.2k) - 6Moons review

Do a search here and on Audio Asylum, this preamp has gotten a lot of good reviews by users.

Art Audio VPS-DM - fully dual mono signal and power supply design. This is a fantastic preamp (1.5k)

SS amps:

McCormack DNA-125 ($1.2k obo)
EnjoyTheMusic review,
Stereo Times review,
Stereophile DNA-225 review(same circuit design, just more power)

Belles 150A Hot Rod or Reference - ($600-$1.6k)
Soundstage review (Reference)

Might also consider Bryston 4B-St or Odyssey Stratos monos

If you are open to newer Class D amps - Wyred 4 Sound SX-1000 or

Channel Island Audio D-200 ($1.3k)

Why not consider a nice integrated? The Cary SLI-80 comes to mind.
I second the integrated suggestion
Third the integrated route.$2500 will buy a very nice IA.
Darkmoebius, Thanks, I have a couple questions...there is a Bryston 3B-ST available locally for $750. Otherwise there is a 4B-ST on Audiogon for $1350. Is the 3B something to consider, or is the 4B definitely worth the extra $$$?

I've heard a lot about the Mccormack DNA-125. Should I be concerned about the age of this amp?

In brief, what are the downsides to class d amps?

Would you recommend the Odyssey Stratos Extremes dual?:

Thanks, this is a HUGE help
The Cary IA write-ups seem very positive for jazz, blues, classical. Are there other recommendations for specific IA's in this price range? What is the benefit of IA's over separates? Thanks!
Audible Illusions M3A OR L2 are amazing pre's. I had the M3A and replaced it with an L2 for remote capability. Used pieces run approx. 800-1200. As far as amps go, I would go SS if you choose a tubed pre. Monarchy Audio amps are a very nice compliment to tubed pre's (for the most part).

Big vote for Modwright SWL9.0 and a good SS amp. The IA route is not a bad way to go either ... maximize your buck. I like the flexibility of separates. If you like to play with upgrades from time to time you may want to go that route. I am looking at a Plinius SA-50 as a possible next upgrade for SS power. I'll keep my Modwright SWL 9.0 ... unless I go for the 36.5 (gulp).
The Bryston 2,3,4b-st amps are very solidstate like.No worries with McCormack,Steve is great to deal with.Stratos are also excellent amps,differing in the warmth department.
Must disagree with the AI-it burns thru tubes and they are slow-as-molasses on updates.
Wyred and Modwright is a very good combo. Wyred also has an integrated.
Odyssey sounds very good but not sure how it sounds with Modwright.
at least consider seeking out a forte amp and pre, and maybe keep some money.
Your current speakers aren't a good match for tube amps. Be careful mating tube preamps with solid state amps. Most integrated amps don't provide main amp in jacks which then limit their usefulness. I'd pick a preamp and amp from the Parasound Halo line. Or if your source(s) are digital only, then I'd consider a Benchmark DAC1 Pre with either a Parasound or ATI amp.
If you are definitely planning on upgrading your speakers in the near future, I recommend that you not upgrade your preamp and amp now. (I realize that this is not what you want to hear, but IMHO, that is the best way for you to approach upgrading your system.)

Pick out the speakers that you want, and then match your future power amp, (or integrated amp), to your speakers.

The amp to speaker synergy is very important, and to pick your amp first, will limit your selection of speakers that will sound good with your amps.
(i.e. as examples; a power hungry speaker will not work with a low powered amp, or a speaker that has a very low impedance, may severely tax the power of an amp that does not double in power as the impedance is halved.)

My two cents worth anyway.
Used Pass Aleph gear. Aleph P preamp for under $1000 and Aleph 3 for under $1000, Aleph 5 for $1400, or Aleph 2 for around $2K. I had all of these and for the price, they are excellent. You could also look at used FirstWatt, though you would have less power.
Like Kurt_tank, I too am wondering how attached you are to your speakers. With $2500 to spend on amplification, you could easily outclass the 602s. I think Kurt is giving you advise worthy of consideration.
I have a Conrad Johnson MF 2250 in my "2nd system", along with a C-J PF-R SS Preamp. Paid about $2K for the pair a few years ago, love them.

I had a McCormack DNA .5 for a few days once. The seller had shipped it so poorly that the entire metal case was bent, & twisted. It not only worked (!), but sounded very nice.

An MF2500, or DNA 1, would be other SS ideas......
Kurt_tank advice is priceless. If you are going to invest in your system, settle on the speakers first or you will start going around in circles; the speakers will then inform your amplifier options. I think your current speakers are not suitable for tube amps in your price range, they really are best suited for SS.
You can thank Kurt_Tank now or you can thank him later.
What ever you do HEED his advise.
I agree you should get an integrated amp instead of separetes, ICs get too costly...

however, if you do buy a power amp do not buy the Quad 99 but the 909 instead, it is supposed to be the better of the two...
As Kurt_Tank mentioned, it was advice that I didn't want to hear, however I'm glad he mentioned it. I'm not in the habit of continually swapping gear and I'd rather have more options when shopping for speakers. It looks I need to start researching Speakers, on which you'll probably see another thread from me shortly asking for advice.
Thanks everyone for your replies. I've been researching each and every suggestion posted.
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.

Maybe some cornerhorns like classic Klipsch? They are big and rock hard. But get tucked into corners so they are out of the way. The only problem is that you would probably have to find some locally because they won' be an easy ship.

Here's some Speakerlab Klipschorn remakes for $800 in central, IL.

Those Paradigms are a great suggestion, too.
The Klipschorns really open up some great amp/preamp combos. They are so efficeint you can use any flea powered amp you want and drive the snot out of the Klipsch.

I think the Klipschorns driven by McIntosh gear is an incredible sound. I like the MC225 amp with the C22 pre, great combo!!
