Allnic L8000DHT with Pass XA60.8 on Mangepan 3.7i's. Amazing but the input sensitivity of the Pass is 1.1V to full output. I ordered a second set of low output DHT tubes but still can hardly get to 12 oclock on the attenuator. Fortunately the Allnic has a constant impedance attenuator so it doesnt need to get wide open to sound its best.
I would have paid more attention to the pre-amp output and sensitivity of the amp if I had known to. The Allnic is my forever pre-amp, I am not looking to change the Pass amps at this time but if I do I will look for a higher input sensitivity like 2.6 volts.
