I am still waiting for mine from Arthur of Power Holding. Mine should ship soon.

It's here!

It looks great, congratulations!

Thanks! And sound even better

It's a bit strange how the potentiometer in my US5 Pro is calibrated, to get the desired volume level I have to turn the knob to almost half of the scale. Neither on my previous US4 nor in the US5 Pro demo did I have to turn the potentiometer so high (see my previous posts). In all of them my gain was set to 0.

Are you sure the pre gain is that the same for all?

Is there much difference sound wise between the 4 and the 5 Pro?

I'm 100% sure.

Not really, to be honest US5 Pro sound little worse but is new and needs at least 50h burn in time.

That's weird about the volume difference. Any chance you accidentally changed the setting on your source? Aside from that, and the gain setting which you already checked, I can't think what else it could be.

Theoretically the 4 and the 5 should sound identical, they have the same internal layout but the 5 has that extra 4.4 output.

Nah, Morpheus is still at 0dbF. Im not worried about that too much becouse i don't hear any distortion. Just level of power grow very slowly. They should after US5 Pro burn in time.

Conspiratorial theory: Maybe the components in US5 (Pro) are of lower quality than the previous US4 (+) due to covid (parts problem). Currently, the sound of the US5 Pro is to my ears somewhere between my previous US4 and the V550 Pro. I just hope I'm wrong.

that is extremely disappointing..I briefly had a 550 which I had to return due to a malfunction so I couldnt properly ascertain its merits but what I did hear didnt overly impress
