Audio Research ARC Ref 5 versions?


Hi,
Would anyone know if, apart of the obvious SE version, there were differences between earlier units of the Ref 5 and more recent ones?
If so, when was the "cut" between earlier and recent?
Thanks.

thanks Gpgr4blu, this is also what the guys at ARC say.
I think I'm going to go for one...
I just received a Ref 5SE. It is a wonderful unit. Much better than the LS27 it replaced; and, I was very happy with the LS.

Thanks,
Mike
I hope the new version is much better. Musically the LS27 bettered the ref 5, which I've never wanted to post til they either improved or deleted the 5.
Good to hear it's a winner.
