Phono pre "Break-In" process? Necessary?


Just ordered a new phono preamp from Jolida  (J9II). Is there a break in process I should be aware of? Or do I simply play normal and realistically believe that it will open up as time goes on. Also, how much can one expect this pre will improve over time?

Well, there are obviously lots of reasons why a system might lack focus including, but are not limited to, lack of vibration isolation, lack of sufficient or correctly placed room treatments, disregard for cable and fuse directionality, disregard for absolute polarity of the system, there is at least one problem in the system, disregard for the magnetic field produced by large transformers, insufficient damping of circuit boards and CD transport mechanism and non optimum speaker locations.

geoffkait,

Your right - the odds are against having things work properly.

Of course there is break-in required to get the best out of ANY electric or mechanical gear!
It's ludicrous to think otherwise. 
But how long and how much difference it will make varies. 

But who cares? Just enjoy it from hour 1 and know it will improve!

Don't waste time "burning in". Just enjoy it from the start. 

Life is already too complicated to worry about this. 
Following this thread has lead me towards ‘burn-out’. Regarding ‘burn-in’, as a function of use, if we did not follow the process, we needn’t purchased the product.
Surge, you comment seems dismissive to the point of displaying a simple lack of high-end experience.

In that, I just got back from a friend’s house where he had a very nice set up including Pass Labs amplification, Wilson Sasha 2’s, a VPI classic 3 turntable (that I had set-up), and a mishmash of good old interconnect cables, speaker cables, and power cords. Overall, his sound was very good, natural, and convincing. It had a nice relaxed feel and we could just focus on the music, playing record, after record.

Well he finally had the chance to break down and drop some serious dollars on a real nice full loom of Tara Labs cables. By all rights, this should take his kit to a much more refined level of performance overall. So we couldn’t resist, we stripped out all the old stuff, put these new ones in cold out of the UPS box, and guess what? The sound was completely confusing both timbre and soundstage where a complete harsh, smeared mess, the system was unlistenable and a total waste of time, I mean, down right nasty. Two days later? Still unlistenable.

I have been here so many times. I told my friend that we either needed a burner service or we would have to do it the long hard way by downloading a sweep track or use a burn CD and let these run for a week or two without listening.

The bottom line here is that the more resolving a system is, and the more experienced your ears become, burn-in is more easily recognizable as a real necessity, not just voodoo, or a figment of someone’s imagination. One could not just have plugged them in and sit down and enjoy the music. (And this is no reflection on the cable maker or dealer. It is just a matter of fact and I have no doubt that once they are burned in, we will experience killer performance like many of their cables I have experienced before.)
