Do you think that if already burn in equipment is shipped to another location needs burn in/settling in?
Equipment settling in
- Thread starter jasbirnandra
- Start date
Absolutely. Anyone who has exhibited equipment at a trade show has seen this effect. It can take 2+ days before the equipment sounds like it did before it was moved. For 3-day shows, Sunday is ALWAYS the best day to listen.
My theory as to why this happens:
1) electronics absorbs charge during shipping, all of the dielectrics, so this has to bleed-off
2) speakers get jarred or are shipped in non-optimal positions and the drivers are not exercised for many days, so the drivers need to loosen-up
3) cables are flexed, disturbing crystal lattice in the conductors. Need to settle-in. This one is far-fetched, I know....
4) contacts are newly made in connections, so the metal-metal interface must come to equilibrium for good current transfer, particularly transients

Thanks Steve...great to hear from a professional. I would imagine (given that it is December)...coming in from the cold does not help either. Being Flown at -25 degrees at 50,000 feet for 6 hours from NYC to Seattle (and left outdoors at somepoint in transit on truck...probably also has quite an effect i would imagine.
For cables I think it's the movement of the dielectric in relation to the conductor.
It's less of an issue with litz wire, which has a very thin enamel dielectric that won't move wrt the conductor vs cables with conventional wire.
I think the effects of shipping are due to both mechanical stress as well as temperature changes.

30 min for general use seems appropriate warm-in for a lot of stuff. But memory in capacitors can take longer when changing the equipment, or AC voltage.
In my experience yes. I also find most equipment needs time when not used for an extended period of time. How long? After two week vacations, it usually takes about 4 hours for me. For pieces that have been out for months usually 2 to 3 days of listening (at 3 to 4 hours each minus warm up time of 45 minutes).
Funny related question. Has anybody got an answer for this? What exactly causes that new amp smell as they are fired up for the first time in your home?

It isn't so odd really IMO. Big capacitors in audio gear take a long time to charge and run at 100% operation. New gear is another subject, as parts, transformers, cpas, resistors and even wiring seems to need 4 weeks. I had V-Cap Teflon caps that too 500 hours at least. And yes, I agree, if left unused for a month or more, it needs to be fully run in again but this time can be a few days as opposed to a month.
I tend to leave SS amps on 24/7, tube pre-amps or tube DACs on 24/7, and computer sever in sleep mode.
Cables' dielectric need to be re-charged again after unplugged from signal grid.
Which is a good thing.
