Do You Have to Play a Component to Warm it Up?

It’s hard to understand how any component requires more than 30 minutes to an hour to reach operating temps. My h390 seems fine pretty quickly. 

Back to the original question/post at hand.

My old 70's Sansui 8080 would get hot when cranked for quite a while so I put a muffin fan on it.  It certainly helped and everyone noticed the sound didn't flatten out any longer.  Sounded good cold though.

My Krell FPB amp does like to be played a bit to get the components warmed up, or so I figure.  Like I said years ago, I feed the fish, cook dinner and clean up a bit whilst it plays.  After that all is well.   And yes, this is the same amp stuck at Krell in CT while they re-organize after the owners passing.  The KCT pre-amp is always on, or so it seems, as it stays very warm to the touch.  I feel the on/off switch is there for decoration.  

asvjerry:  I am getting up there myself.  One of the prime things that keep me moving forward and smiling is to remember I have a lot of living to do yet so I better keep going.  Even with CIDP I enjoy & relish the day.  I hope it helps you get a better outlook.  Maybe a Happy Birthday from someone you don't know will help a bit..  All the best, John

...back to the topic at hand...

I fully power down my equipment as I don't listen every day and to have them on "standby" in my mind is a waste of electricity.

I do find that after about 10 minutes my system seems to sound a very slight amount "warmer".  I'm not sure if it's the equipment, or the listener settling in.

My system improves for the first 20-30 minutes.

Congestion is diminished and soundstage and imaging improve,

Hi @fleschler

Did you compared your cdt3 vs et3 transport head to head?

If yes, what is a difference in sound?

I always leave my cd transport and DAC on. My 300b SET starts sound better after 1 hour and continue to improve. After 2 hours the sound doesn’t change too much. I need to check if volume is important during amplifier and speakers warm up.
