I have Shunyata Alpha HC on both the REF150 and the LS25 Mk1. I do not have a Shunyata Triton.
Currently have Hydra alphas - 4 and 6. With the 2 VT100s Mk2s, I had two Alpha HCs on the amps and an Alpha analog on the pre-amp. Hydra 6 is connected to the wall using a Sigma HC power cord. Amp goes directly into the wall as I found that the Hydra seemed to limit the amp.
