Audio Research Ref 10 vs 40th Anniversary preamp

I’d give a call to Randy at Optimal Enchantment in Santa Monica and ask him. He sold me my Ref 40 and now sells lots of Ref 10s. I suspect the answer is that they sound similar but that the Ref 10 delivers more of the same ... now I suspect we’re waiting for the Ref 50 in a year or two 😉

folkfreak......Ive had the Ref 5se and now the Ref 6... There is a night and day differ between them. Im wondering if the Ref 6 is closer to more of the Ref 40 anniv. 

There was always a night and day differ between their endless Reference etc. Products.
What does Reference mean? Their Reference?
Or a Reference among comeptitors? (Well, hardly)
Probably it is time to think about a Manufacturer who can do something right the first time.

This is obviously not the way it works or otherwise you would still be driving Ford Model T’s and the electric starter and air conditioning would never have been invented and you would be expressing you ill-informed "opinion" with a quill pen on parchment and posting it to "Pony Express"!
