Amp/Preamp upgrade advice

A buddy of mine has Adcom GFA-555 amp (he has two, one was refreshed) and matching preamp. He runs a lot of vinyl and has a decent TT and phono preamp. He also has a decent CD player, IIRC it’s a Pioneer Elite, and he has some vintage Essence speakers and also some Definitives. He wants to upgrade his amp/preamp (not opposed to an integrated) and has a budget of $3K. Not interested in tubes. Any suggestion's for him? He said he’d sell the Adcoms. What are they worth? Thanks in advance.

I should add that he’s thinking of dipping his toes into streaming.

Maybe one of those new-ish Cambridge Audio EVO all in ones?

Thanks. Do you think the SQ would be noticeably better than the Adcom? I’m sure he’d appreciate the move into the 21st century. 😎

I'm not sure as I don't have experience with either, but he could always return it within the 60 day window if he doesn't like the sound quality.

An 11.68 lb 150 wpc integrated would have me looking elsewhere and I really like my CA streamer.

he could always try this:

I have not heard it so not much help here...
Then go for a CD player/streamer.

or something in the C-note area to see if he likes it.Speakers: Polk Lsim, ATC SCM19 v2, NHT SuperzeroSpeaker Cables: DH Labs, Transparent, Wireworld, Canare, Monster: Beer budget, Bose ears -
It's Class-D you curmudgeon.

Thanks, fellas.
-
What is wrong with the refurbished adcom he has? Maybe just add a better preamp in front of it.
-
That actually what I suggested to him. Any suggestions?

I cast my vote for a Benchmark DAC3/HGC Preamp. I started with one of these to use for both DAC and preamp duties, and it served me quite well. Eventually, I moved to a Benchmark HPA4 for preamp duty, BUT kept the DAC3/HGC as my standalone DAC. The 'H' in both cases refers to headphone capabilities, but if that's not needed, there are other models to choose from.
I have used both of the above with several different power amps, and have never had a problem with impedance matching. These units are not 'sexy' looking at all, but IME they perform quite well.
P.S. Your friend's Pioneer CD player could have the digital-out sent to the DAC section, and compare to the CDP's DAC. Lots of ways to incorporate streaming into the DAC as well."This may not matter to you, but it does to me for various reasons, many of them illogical or irrational, but the vinyl hobby is not really logical or rational..." - member on Vinyl Engine

This would be my next amp ..
Tons and tons of clean power …
If you don’t like the looks , it comes in a more “upscale” enclosure as well …

As @F1nut pointed out, a Marantz stack would be sweet.
I'd have gone that way if they existed before I bought my
Yamaha. (I still like the Yamaha and use it in the second system)

It's just kindof a shame that at $3k MSRP, you aren't getting PM-14S1 quality here. -
Thanks, y’all

Because I don't take advice from anyone that has an agenda to push. I make my own decisions. When a site can trash products made by the biggest names (Levinson, Pass, Carver, Krell and many others) as well as attempt to trash established and well-respected publications and reviewers, I question the motives of the site.
My experience over decades in this hobby are worth more to me than taking the advice of a bunch of herd-following hacks.The Gear...

I've spent a good amount of time with one of these:

It's a great and very flexible integrated. -
Very nice. Looks similar inside to my Michi X3. Probably some trickle-down effect going on.

I love my arcam sa-30 integrated with built in streamer. The streamer sounds great and it very easy to use. I don’t use the amp - my musical fidelity powers the speakers in HT bypass mode…
I also drooled over the NAD M32. I would have tried it except I really wanted the Dirac live that the arcam has, and the M33 (which also has Dirac) is much more expensive…Living Room 2.2: Usher BE-718 "tiny dancers"; Dual DIY Dayton audio RSS210HF-4 Subs with Dayton SPA-250 amps; Arcam SA30; Musical Fidelity A308; Sony UBP-x1000es; Squeezebox Touch with Bolder Power Supply
