Audio Research Ref 10 vs 40th Anniversary preamp

As above,Optimal Enchantment (great name for an Audio shop) is a Hallmark for retail brick-and-mortar that has been around for a long time. I can remember their ads in Stereophile / TAS back in the 1990's. Good to read that these guys are alive and well.Happy Listening!

Just traded in my ARC Ref 5SE for a ARC Ref 6 today.  Here are my reactions, …  FWIW.  

Is the Ref 6 a better sounding unit than the Ref 5SE?  IMO, yes.  Here's why.  First off, bass is tighter, but not in an exaggerated sense.  Just better low end and midrange detail.  The sound stage is more open.  I get a sense that there's less clutter to the imaging and a more coherent presentation of the musical performance.  To my old ears, it is a palpable difference.  To die for?  No.  But to appreciate and enjoy?  Yes. 

That said, do I think the Ref 5SE is a sonic slouch?  Absolutely not!  Both units share similar ARC house sound characteristics.  But the Ref 6 does tease out more detail and a better sense of a uniform sound stage with few gaps.  

I surmise that the Ref 10 and Ref 40 are of similar genre to the Ref 6, ... just more of the same.  Admittedly, I have never heard the Ref 10 or Ref 40, but generously assume (based on member comments) that they are a cut above the Ref 6.

As I listen to more source material, I will add more comments if I think worth passing along.

Was wondering if any of you guys could tell me what you think a good price on a ARC 40th Anniversary pre is?

At what price is it too much and am I better off just moving to a newer ARC pre model?

Is it better or as good as a 6? They seem to be around same price as a 6?

Trying to decide on a non tuby tube pre for a pair of Pass Labs XA-160.8 mono's driving Magico S5 MK II's. Thanks  

@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 ...
