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?

Like most electronic equipment, it will probably take 600 to 1000 hours.

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.

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
