    @dstarr3 if you cannot get it rma'd your plan to use the wall switch will be fine. What's happened, for whatever reason, is the mosfet switch which sits in standby has shorted leaving the amp on all the time. You will neither do the amp, nor the tubes any harm with your work around. A little...

    @Philimon typically low bass is difficult to localize ( obviously more directional in headphones) but i would try listen to general music as opposed to specific test tones or sweeps. I suspect that your brain will "autocorrect" for it to sound pretty decent. looking at the test results -...

    Congrats, I doubt this will have significant impact on the sound.

    You are approaching this the only way it can be done. Trial and error till you find your sweet spot. It always fascinates me how you can get so close and then tweak a little more and lose the thread altogether. Your mission to get this right has inspired me to revisit some older attempts that I...

    Don't assume that you are hearing the amp noise floor. Ground the inputs and repeat. If you don't hear it this time round, the noise is coming from the source. With that said, if I use sensitive headphones with almost any amp and turn it up to max, there is a low level white noise from the...

    Well after a long hiatus and after letting my Yhd1 go to a fellow planar, I impulse bought an HP1. And so the cycle repeats itself.... :) .. dB

    For those who have not seen atomicbob's measurements, they near mimic those of the Crimson and this is what he had to say about the stock power brick. "Residual noise is non-existent, with provided SMPS. All of the measurements represent engineering excellence. Well done Dr. Cavalli!" ...

    You may have missed my above link but here are the measurements . It is incredible, probably what a true high end amp should look like, very little noise floor. Flat frequency response and near perfect square waves. .. dB

    Opamps are irrelevant, they are control servo only. This amp is discrete front to back. .. dB

    The original Joe Grado HP1 and HP2 are actually very good.
