I demo'd the Red Dragon with my TS speakers amp and after a while found them lifeless, which has been my experience with ever new Class D amps. My M4TM, however, with their 11 ohm impedance, are driven to great pleasure with my McCormack DNA .05 SS amp, but the speakers sound demonstrably better with my Don Sachs KT88-based tube amp... a drastic improvement over the McCormack amp. Your speakers have much lower impedance so tube amps might not work for you as they do with my upgraded speakers. My best advice it to send your TS speakers back for the upgrade the the Triode Masters variant. It was a potent improvement in SQ, particularly in the the LF response and the speakers hence become very tube friendly.
