I went to a store and listened to 160 and fell in love. Since I can't afford it at the moment, I recently bought a used AR REF150 SE. What an amplifier! It is the best amp I have ever owned.
It has explosive dynamics, incredible punch, lots of detail without being sterile, and as mentioned above, it weaves a brutal, layered soundstage. There is a quality that surprises me a lot and that is the palpability of the instruments.
A magnificent amp.
