I have an Emotiva XMC-1 processor and Emotiva XPA 1L Monoblock Amps. The room is 16x21x8. I use an iMac with Audirvana. Even though the TDL's are great on the bottom end I like to use a pair of stacked Kreisel DXD12012 Subwoofers crossed over at 80Hz. I also use Dirac to EQ system. It sounds truly great. When. They were new I bi-wired the TDL's with a pair of Bryston 4B's. The room back then was 14x28x8. The TDL's loved that room.
