No only phono and one of the line inputs
Do All Input Channel Need Equal Break-In?
I'm trying a brand new Pathos Classic Remix integrated from Upscale Audio. They suggested at least 200 hours of break-in before judging it. I have been playing CDs about 10 hours per day for about 14 days now.
I just started playing records, which is going through a different input. While the power amp part of the unit has been being 'exercised', as well as most of the preamp, I'm wondering if each input needs getting their own break-in period (albeit a shorter individual one, I imagine)?
I did some playing through the headphone output (and it has its own power supply), and that, indeed, did change over some time.
In the case of the headphone amp in the Classic Remix, I believe it's its own circuit (and it has its own dedicated power supply), so that will need some breaking in.
And thank you, @rocray!
