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.

Theo,

The Ref 5SE is much better than the LS27. I replaced the LS with the Ref. I can tell you that the difference is not subtle. BTW, I was a very happy owner of the LS.

Good to hear, Mike. I was sure hoping so.
Now with the LS 27 and newer ref5 se, ARC preamps are again at the top of the heap.
Have fun!
Does anyone know if Ref 5 will be upgradeable to SE and if so, at what cost?
