Thiel cs2.3

short answer to op's query is get an upper hegel and be done

power and control, sounds heavenly...

^Hegel doesn’t spec their amps below 8 Ohms. Typically if a manufacturer can deliver the appropriate power output into lower impedances they’ll brag about it.

Bryston 4B, the newer the better. (Bryston/Thiel for 20+ years)

The Bryston 4B is not rated into 2 Ohms. The earlier version's measurements show that rather than increasing it's power output into 2 Ohms it loses power output.

218W into 2 ohms is more than 100 amps going to the speakers, easily enough to start a fire. I have a 1996 4B, amongst others, and the combination works well. But the newer 4B3 sounds better in every way because everything is different - circuit, components, boards etc. 4B3 also has a slightly warmer sound than previous 4Bs and can be useful if you want the Bryston detail with a less uncompromising presentation.
