I recently listened to a friend's system that is comprised of the EB1i driven by one 4B-SST. Source is a Mac to an Ayre DAC. Sounds good with exemplary bass notes. He is contemplating of getting another two units of 4B-SST since the speakers can be tri-amped. He was advised by the dealer than the bigger PMCs need a lot of power to come alive. Another factor to consider is the passive PMCs can be converted to actives by some modifications which will totally transform them to another league.
Not too sure the purpose of this thread but if you are considering PMC speakers, do consider the bigger ones if possible -OB1i and above. My friend said that he would never go back to smaller speakers after listening to the EB1i mainly due to the very full and deep bass coming out from these transmission line speakers. One can literally feel the thumping bass notes hitting the chest. He mentioned he cannot get that with his previous Audio Physics Scorpio driven by Nagra which the system was completely outclassed by the Bryston/PMC. Voices also sound real and uncolored albeit some can sound little harsh and glaring mainly due to the audio files ripped from less than perfect CDs. Overall it was still very listenable.
He didn't try any other amps with the EB1i.
