Use pink noise disc to warm up stereo

Those who find there system lacking at start-up should try a pink noise disc.
By covering  the whole spectrum of frequencies, warm-up time is effectively  decreased.  It has made a huge difference in my enjoyment, not having to suffer through the crappy sound of discs played before the set is ready for prime time.

There are also a number of free phone/tablet apps that generate pink noise if you have a Bluetooth capable streaming device. Handy for speaker placement as well.

My SS Pass Labs and as well as my expensive digital gear always sounds better after they’re on for at least an hour. (They must not be well designed.)

Once again we have to ignore posters that pose theoretical comments. (When will they get it?)

Just playing music works fine.

Hmmm. Odd. I find just being turned on for a bit does the job. Which is odd, as I have a similar setup to rvp: dared tube pre and Ghent Audio class D monoblocks

Do not keep tube amps on all the time. That's a fire waiting to happen.
