We no longer offer HT-bypass on the new P-8S. The older P-8 is capable of HT-bypass on input 3 but has to be programmed at the factory. We do have a few copper or gold color P-8 in stock that we can sell at discount and program the HT-bypass.
If you want the absolutely best bypass solution, go with the more expensive P-9. When you "turn off" P-9 using the remote control (in this case, the power is not completely off), any input becomes HT-bypass.
