Audio Research VT80SE amp vs Prima Luna EVO 400 or 300


It’s time to get a newer tube amp after years of happy listening to vintage mono tube amps- MFA M-120 to be precise. I will mate the new amp with my upgraded/updated MFA Luminescence preamp and power Sonus Faber Guarneri Homage speakers. The Lumi is deservedly a legend and has a fabulous phono stage, to boot.

I’ve read many reviews and comments about both the ARC and the Prima Luna gear but would greatly appreciate a response from folks who’ve had experience with either one or the other or preferably both.

My musical tastes are quite eclectic, but primarily "classical" and do not include heavy metal, nor much R+R or pop at this stage of my life. I’m partial to what some might call warm, romantic and "euphonic," and from what I know, Audio Research tends to be less "euphonic" than some other tube components. At the same time, I enjoy listening to subtle details that more syrupy components can obscure. Unfortunately, I cannot audition anything prior to purchase, neither in my home nor at a dealer.  After much experimentation, I am convinced that SF GH's LOVE tubes!

Thanks in advance. Stay safe. Be well.

@jrw1971"I waffle between my teenage brain seeking punch and sizzle, to a more adult appetite for effortlessness and flow."i can relate, even tho' I'm well into my "golden years."  My wallet is a bit too thin for the upper echelon ARC gear but happy for you!

@sandthemall
Very helpful, sir. Thanks
Interesting thread. I am thinking that since the OP owns the same speakers as I do, that the answer to his question is going to be highly dependent on the rest of his gear-- and his room.
While IMO the GH’s can sound warm...they are actually not really a ’warm’ speaker. The GH’s, at least IMHO, are so revealing that if you place ’warm’ sounding gear upstream, along with cabling that enhances that...yes, you will get a very warm presentation. OTOH, if you place more revealing and ’neutral’ gear upstream, and cable for that, then you will get a ’neutral’ sound out of the GH’s. The synergy with the GH’s..and the room/gear, is the decider here. Personally, the amp question is a no-brainer to me...and the answer is the ARC.
Thanks jrw,

My experience has been exactly as yours. 
I had intended to go ref 160s from my ref 75, but found the sound different - as you say. Better in some ways, but at the same time another step in the direction I experienced going from Ref110 to Ref75 (I still miss the low level late night listening on the ref110 - tubey magic).

Anyway, my thought, that you have helped validate, is perhaps PS should consider a lightly used ref75 for similar money to the VT80? I think if you do you won’t be disappointed and you will always be able to move it on and get good money back.

I regret selling mine, they are very special.
Thanks to DaveyF for weighing in.  His description of the Guarnieri Homage speakers is accurate and much better articulated than mine. 

At this point, I'm leaning toward Audio Research- there are some obvious and other reasons.
  @flame, thanks for your suggestion re: the ref75. Oh, good, more homework for me!  I rarely change quality components so this is a fun adventure.
