solid-state class-A integrated amplifiers

Something to think about....

The McIntosh MA252 (my brother has one and absolutely loves it) and the MA352, both of which are new designs are wonderful integrated amps. Tube pre and SS amp section. The MA352 is more advanced.

generically speaking, putting a pre-amp between the a source and power amp is probably good for SQ... and my inclination is still to keep with an integrated... keeps the box count down as well as the cabling. also, a bit friendlier on the wallet all else equal.

otoh, a tubed pre amp into a class-A, SS amp probably sounds like something to explore -- i am not sure if that exists as an integrated, anyone know?

the pass and sugden certainly look like the real deal in this niche area... still more to learn though.

thanks to all for the help!!

Dang it Joe, you beat me to it :). I was just about to mention the new McIntosh's. Being a Binghamton boy I have been thinking about these lately!
 
The MA352 would be perfect but the MA252 has all the features I truly need.

I like the way they do not include a DAC. It drives me crazy that all their pre-amps and other integrateds have DACs. Even their new replaceable modules are not what I would want :).

I also like that they have sub outputs.

I would love to try one but I also am not sure if the Amp would be as good sounding as the T+A and the T+A might be hard to move without giving it away (not as well known in the U.S. :().

i have thought more than once about those two amps!!

however, i seem to be stuck on class-A ...rightly or wrongly. trying to keep the characteristics of a SET amp as much as possible but gain some speed and low-end authority.

this would not be a replacement for the almarro -- that amp stays to the bitter end and my heirs can fight over it -- just a second amp to rotate in once in a while for a change.

seeing your stable of amps makes me think i should have at least two, right?! :)

Absolutely! I've had over a dozen at once, several times. I am trying to be a little more judicious in case something pops up next year that I just can't resist ;)
 
I definitely understand where you are coming from about class A. I was stuck on it also for sometime and had amazing Class A Audio Mirror amps. They sounded fantastic, but I found switching back and forth with the T+A Amp I keep wanting to listen to the T+A whenever I hooked up the Audio Mirror's.

I finally realized that the Amp 8, with the extreme high level parts used, High Voltage design inherited from their HV series, and the ultra wide bandwidth had very much the characteristics that I loved with Class A, but it had none of the negatives. So I sold the AM Class A amps and put the T+A into full time duty. It has been very happy with me for that :D.

Unfortunately I have been in the re-discovery, re-building phase since jumping back in, so I can't afford to retain extra pieces :).

I’d say older Pass INT30A might be what you’re looking for.

A Pass INT-60 might be to your liking. Up to 28W in Class A, all you need for your Vikings

Auditioned one. They make the world a better place. Seriously, killer, sweet sounding amp. Class A warmth in spades, great spectral balance (lows to highs), wide, deep, sound stage, really good dynamics, good slam. Pretty much checks all the boxes with my ears.

Sounds superb at low, medium, and high volume (in small to medium sized rooms). I especially like an amp that sounds great at low to medium volumes. Some amps don't sound all that well at low volume levels. This isn't one of them. Sounds great at all volume settings. Typical ultra high quality Pass craftsmanship. Pass Labs is a company very well known for it's excellent customer service.

Simple design and layout with almost nothing to clutter the signal path or create distortion. IMHO, one of the top two or three integrated amps in it's power and price range. I wasn't even going to audition the int 60, but I'm sure glad I did. It really grabbed me and drew me in when the music began to play. It's just a great amp any way you look at it.

Disclaimer...if I sound like a bit of a Pass fanboy, well...unashamedly, I am. But it's for all the reasons mentioned above. I'm such a fan that I have not only auditioned an int 60, I have a Pass int 250 on order. I know they sound a little different from each other with more extension into the higher and lower ranges in the int 250. But if the int 250 sounds anywhere nearly as good as the int 60, I'll be a very happy fanboy. My 2 cents.
 
Croft Acoustics make an integrated with a solid state amp section and a tube preamp section. I was seriously considering one. Around 50wpc I think, and around $1,600 new. Would probably drive your Berlin's very well.

...for grins i pulled a 20+ year old adcom amp that had not seen the light of day in 8 years out of the closet and hooked it up in my system. input was direct from the t+a dac8 dsd with the volume control enabled. i was not expecting much; however, i must say it sounded pretty good in certain respects. nowhere near the musicality of the almarro and the mids were pretty flat in comparison... but, it was quick and had a firm grip on the bass.

anyway, this experiment was an interesting A/B test and certainly encourages me to further explore SS class-A amplification.

so... i left the adcom gfa 5400 solid state amp in my system for the week, listening to it for 2+ hours per day.

i must say it was certainly nice listening to this modest amp as a change. back in the day it was a very entry-level audiophile amp, nothing anyone would call high-end. despite that and after several days of listening, i thought it was actually a quite good amp and it fit nicely into my system with its 125 watts certainly being enough power to give it a full sound. if it were the only amp i had, then i would not be unhappy.

well, last night i switched the 18 wpc almarro SET tube amp back into the system... ahhhhhh! it was glorious -- now i know why i love this amp and why it had received so many great reviews.

anyway, while i probably only reaffirmed that i am most definitely a SET tube amp person, it was really nice to have something to rotate into system for a change. also, maybe that second amp should just be another tube amp... or at least a higher power SS amp, say 75 wpc or more.

thanks to all here for the information and helping focus this line of exploration.
