as I said earlier I'm a fervent believer of the burn-in phenomenon, having recapped / upgraded many of my electronics and heard a major improvement every time with some hours on it; but in those cases it was obvious, as the fresh caps were pretty much unlistenable out of the box, with weird phenomenons such as shut-in midrange and rough high frequencies, or "dull in the afternoon, bright in the evening" sound then nasal the morning after then dull again etc... but here it sounds good but overly sibilant, which makes me wonder if there's more burn-in needed or if that sibilant sound is going to stay.
The worse case of "bad fresh caps sound" was with Elna silmics, which sound dull and bloated as long as burn in isn't complete, to the point of having me wondering if I had accidentally damaged something, when a certain number of Silmics had been placed in the circuit.I almost never buy brand new electronics, with the notable exception of my new DAC which sounded nasal, metallic and very bass shy for about 4 weeks before the sound became good (which happened in a very sudden fashion, like you are doing something else while listening music and suddenly it all pops into place and you stop what you were busy doing with an incredule look on your face); brand new, the DAC was so disappointing I was reluctantly thinking of getting rid of it...
I also heard it with some op-amps, specially with LM4562 which in my experience sound thin and sharp until they finally mellow down at around 100hours of use (I wonder why it's almost always 100hours, it's very weird, makes one feel delusional and brings arguments to the "burn-in is a myth" crowd)
Hell, I believe I can even hear a fresh solder joint "mellowing in" after a couple hours; when freshly made there's always something strange happening to the sound... but I've often wondered if it was not just in my head - even tho other people seem to hear that as well.
