Pathos Logos - Volume control problem

Posting for a friend.
Turned the power on, and once ready to go.
Just touch the volume control from zero to the first notch up and the volume starts blasting (at almost full gain)!
Have to immediately power down to avoid any possible damage on the speakers.

Anyone any suggestions on what I should do? other than sending the unit out to the dealer for service. Would appreciate any input.

Thanks

Sorry. I forgot to ask if the amp has a phono preamp?

Is this a new amp, or is it new to your friend? Could there be a unity gain input he is inadvertently using?

I was thinking that you may have a combo of a very efficient speaker and a high gain source, or maybe even using a phono preamp by mistake. Given that you have no phono input and your speakers are anything but efficient, I'm not sure what the problem is. You may have a problem with your amp. Try using a different input on your amp, and also a different source. The Oppo by itself, without the DAC will be OK for a different source.
