Amp comparison

I can't say but I have the Ref 110 and it is significantly better than my old VT 200 at everything except maybe, bass slam.

SE owners seem to love theirs and the hierarchy of ARC models in general offer improvements from old model to new, standard to reference, and probably reference to SE. To what degree I don't know.

That being said, you could get a pair of Ref 210s for the cost of a 150SE.

Or you could try this one:

Thanks for the info,I did see that modded 110 on agon. I think I would go the extra cash for a 150 though.  Also ARC may not even work on a modded ARC unit should it require servicing.

IMO, the ARC 150SE is significantly better than the Ref 150.  I own the 150SE and previously the 150 unmodded.

In what ways is it significantly better?

Thanks
