Still need a power amp. Investigating the AR DS 450. Going to sell the class pre pwr amps along with some Thiel 2.3's and associated cables. Have the system set up to run a Mac Book through the DAC into both the REF3 and Classe pre so I can play through the Max'2s for serious listening or the Powered JBLs for unattended listening.
I'm glad to see ARC coming out with new Class D amp products. ARCs grounding in tube gear seems to translate to their SS amps being designed to work particularly well with tube pre-amps from what I have read. I just picked up my first Class D amps, the Bel Canto ref1000mkii mono blocks and I have been very impressed with these so far running with an ARC sp16 tube pre-amp.
