I bought a high-end BRYSTON digital player and stablemate DAC pre-owned. I sent the player back to BRYSTON for a full software reinstall and general status look over . It went in on or about October 2021 and I got it back on or about March 2022, but only after I personally got ahold of the Service Manager.
If you guys are outraged at five months for a service, I strongly advise you not to get into the vintage watch hobby. Independent watchmakers (whose numbers are dwindling, and typically old) are often backed up for a year or more. I kid you not!
