Audio Research Reference 6 Preamp Review


128x128elem79
Laltik, both seem like great preamps. Not knowing an awful lot about the SP-20 I would probably be more partial to the LS28.  I think that may be the sweeter of the the two based on some of the reviews I've read.  

I didn't get the chance to hear either.  I had a REF 5SE and loved it. When the REF 6 came out I thought it might be a better match for my GS150 and based my purchase of the 6 entirely on the strength of REF 5.  
On a somewhat related note, I've never heard the Ref 6, I own the 40th Anniversary pre. I'm not sure if I'll ever switch, it's been an absolute pleasure. 

However, I do own the new Ref 3 Phono preamp and it's an extraordinary improvement over the Ref 2. The dynamics are incredible. My perception is that I am hearing more information than I was able to glean from my albums in the past. Since the Ref Phono 3 and Ref 6 are fundamentally built on similar platforms, I am encouraged to believe that the positive reports on the Ref 6 are, indeed, true. 

Happy listening!
It would be interested to evaluate both the new Ref6 against the 40th Anniversary edition.
