Esoteric C-03 Break In Time


I've just taken delivery of a new Esoteric C-03 preamplifier. Out of the box this pre is a bit cold and dry. Does anyone have any experience with breaking in their C-03, and how long did it take for the beast to settle down and blossom?

Mine smoothed out after a couple hundred hours.

Put a cd on repeat or leave your tuner on so there is an active input.

Of course leave it powered up as the lack of on/off switch would indicate.

Dealer disclaimer
I agree with the estimate of 600 hrs to 1000 hrs of breakin. . . would not be surprised if the C-03 kept on sweetening until about 1200 hours. Guido

Mine has reached the 200 hour mark and it has smoothed out considerably but is still closed in or narrow if you will. I suspect the large capacitors and power supply require several more hours to totally open up. Solid state gear generally runs cooler than tube stuff so maybe I'm a little impatient. Thanks for any responses
