I owned & really enjoyed the Raven-C's for a few years & ran them w/a Pass X250 & Pass X2 pre & later w/a variety of tube preamps. I once talked to the guys at Talon & they liked high current SS amps w/them & one they talked about was the Sim W-5. They thought my combo was a great one too. They can rock to concert level volumes w/absolute clarity no compression /distortion if you've got the right power & source.
