The advice Dave Belles gives is identical to advice I received from Mondial designs concerning their Aragon 8008BB 200 W/ch power amplifier: turn it off when not in use, it's better from a reliability standpoint, it's better from a power transient susceptibility (e.g., lightning strike) standpoint, it's better from a cost of energy standpoint, and it warms up quickly after turn on. Now that the amp is well broken in, there is no readily discernible difference in the sound between "just turned on" and "warmed up for several hours". And yes, I do have a high resolution system and reasonably good ears, thanks for asking :-)
Is it ok to leave the amp on?
I just bought a Belles 150A three channel amp (used thru this site). I am considering placing on top of a wall unit (due to space problems). This unit does not have an auto-on feature so I would need to leave it on most of the time.. (except when going out of town etc..) What is the general opinion on this.. and is this manufacturer sensative?
