Amp comparison

Thanks all again for the feedback. I am still chewing on this and more feedback would always be welcome.

I had a Ref110 and upgraded to GS150 (the predecessor of the Ref150se) and the difference is striking.  I have not regretted the move for a second.

Ya,I would also consider a GS150  as I have seen some pretty good prices  on agon .

FYI, based on a conversation with Kal at ARC, I understand that the GS 150 is the same as the Ref 150SE, just a different skin.  The specs are identical.  In any case, you can refresh what I understand by calling ARC.  There is a new guy who took over for Kal, … forget his name. 

thanks bifwynne I did hear that the GS150 had a slightly tubier sound than both REF150s.
