Well, congrats Mr. Smith!
That is a bit of a frustrating situation with the long service delay to push you there but with the other ARC gear I suspect the REF 80S was in your future no matter what : )
Is the 150SE operable for you to compare or will you only be going off memory? I truly do hope you have zero doubts and it is a slam dunk upgrade.
The features and aesthetics are fantastic so looking at that amp alone will bring much joy.
I am happier than I have ever been with the 75SE/5SE/2SE and feel quite fortunate to be here. For the first time in my life there is nothing about my system that shows fault. I of course want to upgrade other things for the fun of it but am trying to tame that beast.
Looking forward to hearing your impressions right out of the box and as times goes on. Enjoy!!!!
