Audio Research Ref 10 vs 40th Anniversary preamp


I was wondering what the difference in the sound between the Ref 10 and the 40th ? Not much wrote about that. I btw have the Ref 6 but never heard the 10 or the 40th.

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)
