I have a pair of 1.6's and I use an Ayre V3 of which I find to be the best that I have had in my house. I have tried a Byston 4BST, Krell KSA 100S, Classe CA200 and the Pass Alpha3. Out of all of them I find the Ayre to best match my needs. The Pass was close but not enough power. I'm sure some of the larger Pass unit would have been great but thats what I had available at the time. Just my 2 cents. Best-Gary
