With some of the recent posts and inquiries, I thought it might be a good idea to have a single thread that lists the SP Tech speaker amp/combos that owner's are using/or have used and that work and sound great together. Please disclose if it is a tube, solid state, or "digital" amp and the rated output power into 8 and 4 Ohms. Including room size would also be helpful.
If you guys think this is a worthless thread, Bob can send it to the SP tech waste bin.

Okay, I'll start:
Speakers: SP Tech Continuum 2.5 III
Amps: Theta Citadel 1.5 mono blocks- 425 w/ch 8 Ohms and 625 w/ch into 4 Ohms Solid State. My current amp.
BAT VK-600SE stereo amp- 300 w/ch 8 Ohms and 600 w/ch into 4 Ohms Solid State. Previous amp.
Room size is 21.5' x 17' x 7.5'. Listen to all types of music at moderate, to sometimes loud levels.
