Hi Ben: I leave my Musical Fidelity amp on all the time. It runs in class A up to X amount of watts and then switches to A/B (it idles in class A). It takes a number of days to sound its best after it has been powered down and then started again. When new it took a couple of weeks at 5 or so hours (probably more) a day of playing music to sound the way it does now. I do not know how much of the break in was achieved from just being powered up -vs- it actually running a signal. The nice thing about leaving it on all the time is that it is ready to go when I am. Though I prefer tube amps this is one aspect that I do not miss. David99 had a thread going on his new "Pass" amp that has a lot of info on the subject. Funny thing is that I always leave everything powered up but I swear that my CD player sounds better having played two or three cuts after setting idle for long periods of time. Maybe my ears need to warm up.
Class A amp-best way to burn-in?
Hi-got my new amp today-a class A Sugdena21-any tips for the best way to run it in? I had my dealers on loan about a month ago-his was well-run in--noticed tonight it lacked a bit of weight and sounded ocassionally a little compressed to how I remembered it..this did change after about 4 hours becoming less noticeable.....will simply leaving the amp on all the time do the job? It's hot but it's on a rack thats well aired... Thanks in advance, Ben
