Audio Research Ref 10 vs 40th Anniversary preamp

@fsmithjack re real world pricing I just sold my Ref 40 for $10.5k, I’d say under $11k you are getting a fair price. Only pay above that for a dealer piece with warranty. My piece had new tubes and other extras as well.

I sold it because I came to find the ARC house sound overly warm, lush and colored and that was a poor fit with my new speakers. I switched to the VTL 7.5III which is much more transparent and clean sounding. The Ref 40 sounded nice, but it definitely had a sound ...

fun thread, I have spent a considerable amount of listening time and every now and the. $ with Randy at Optimal. He is always in top echelon of ARC dealers in USA.

I have a REF5se up on Ayre blocks with a NOS Tungsol coke bottle 6550..... yowsa....

when I eventually get the wandering ear the VTL, VAC, et al will be on my list for sure, along w current ARc offerings...who knows, maybe Vandersteen will debut the long rumored preamp to match his wonderful high pass amplifiers...

fun !!!

Hello everyone and happy new year. I’m on a hunt for a new preamp. Changing things over from my hybrid AV/Stereo to strictly 2 channel. Trying to decide on the following:

CJ GAT2 
ARC ref 10
Dag Momentum

Found a dealer demo ref 10 unit with warranty.  One owner reported that Ref 10 is a bit aggressive esp in the treble and at it wasn’t musical. I’d love to get confirmation. 

The CJ GAT 2 has received rave reviews. Only drawback is that it has only RCA inputs.  Is this a deal breaker if your system is balanced. 
The Momentum has some operating issues with the tone control which can be fixed($). 
Rest of my system

focal utopia evo
pacific bal dac
sonore signature/SGC Nas
krell 403 E amp (to be upgraded to monos)

You have selected my 3 favorite preamps. 
 I must disagree with anyone who would say that the Ref 10 is aggressive in the treble or not musical. I find the treble to be spot on. ARC tends to make a large wide and presentation from a front row perspective. This presentation tends to be dramatic (but not inaccurate)-- sort of like technicolor. To me, it is very alluring.
CJ is very true to life, sweet with a mid row presentation and a bit less slam than ARC.
 The DAG is among the best solid state preamplifiers on the market and will be more transparent than either of the tube preamps, but with less liquidity or, for want of a better phrase--je ne sais quoi.
Take what I say with a grain of salt because anyone who favors pure solid state will go with the DAG. But I am also a fan of a tubed pre with a ss amp  If you want to run balanced interconnects, the CJ is a no go as it only uses single ended to my understanding.
Hope this helps.

My vote is for the Audio Research Reference 10 preamp which works extremely well with any solid state power amplifiers (the best of both world)...I have personally compared all three preamplifiers in my system and ended up with the Audio Research.  The Ref 10 is the end game preamplifier...and it is so much fun to own especially when you could roll some tubes and get a different taste!
