Warm-up time.

I would think that the Class D amps shouldn’t take more than a few minutes to warm up.

If the cj preamp is tube based, they do indeed take awhile to reach full potential.

I agree with mofi,

Probably is your cj especially if tube,I usually leave my class d amps on most of the time so my system is ready at a moments notice,I listen at diff. times of the day.But in general class d amps don't need much warm up time that I have noticed.

I hope this helps you,

Those NuForce amps are very efficient, I would leave them on all the time.

I recently got to listen to an ARC integrated, and about 45 minutes is how long it took. It started out OK, then got really grainy for a while, then came out smooth and sweet.

Best,
