So you have a setup with an amplifier, and you’ve played 100’s of hours of music through that amplifier. Can you buy the same model of amplifier, and use it with the original to bi-amp speakers, or will there be a sound difference between the amps?
Obviously we wouldn’t want the L and R channels to sound different because one amp had a “breaking-in” period while the other did not. What experiences with this have you guys had, do you buy into amplifiers having a break-in period at all?
Even if break-in is real (and it might be for some amps, but we don’t have to get into that), it will be just fine after the other amp has played for a while as well.
It’s possible to overthink things. Just enjoy the music.
I did this very thing. Purchased a Benchmark AHB2 that handled amplification duties for a year or so, then with a major speaker upgrade purchased a second AHB2.
I personally don’t believe that there is a break-in period for solid state devices but won’t try to dissuade anyone who does. I did not hear any difference. But if you’re worried, heed @Suedkiez and just listen until they come in to sync!
