Jmcgrogan2, because way too expensive to leave on 24/7. It's like leaving a 1200W blowdryer on.
Amps with short warm up time 4 critical listening
What class A or AB SS mono block amps with min. of 300w per ch. have a very short warm up time to sound it’s best for critical listening? I’m talking about less than one hour. I have a pair of Pass Labs xa160.5 class A amps which take a couple of hours to warm up for critical listening. During that time of warm up I play music at moderate level but I don’t listen to it until it’s 100% at its peak of performance.
