What do you guys think?
The problem here is TERMINOLOGY. Burn-in refers to the process of powering up newly manufactured electronic equipment (mainly a Mil-Spec thing) to make sure its not DOA when its needed in the Field. Most transistors, ICs, and such are going to fail in the first 72 hours if they are poor, weak, or bad. So putting them on a Burn-in rack for 72 hours at operating temperatures and then doing a final alignment/performance check on them before boxing and shipping greatly reduces the probability of a unit arriving to the Field DOA. Burn-in has nothing to do with "Improving" the operation, performance, or sound of electronics, period! Its a reliability thing. As far as dynamic speakers go, it is not Burn-in, it is Break-in. A speaker driver is a mechanical piece of hardware. And as such, the drivers need a Break-in period to find their working area and reach their sweat spot. Similar to a new motor, needing a Break-in period. -- iPhone *iPhone* Media Room: ModWright Platinum Signature Transporter, VTL TL-6.5 Signature Pre-Amp, Ayre MX-R Mono's, VeraStarr 6.4SE 6-channel Amp, Vandersteen Speakers: Quatro Wood Mains, VCC-5 Reference Center, four VSM-1 Signatures, Video: Runco RS 900 CineWide AutoScope 2.35:1, Vandersteen V2W Subwoofer Living Room: Transporter, ADCOM GTP-870HD, Cinepro 3K6SE III Gold, Vandersteen Model 3A Signature, Two 2Wq subs, VCC-2, Two VSM-1 Office: Touch with Vandersteen VSM-1s Kitchen: Touch in-wall mount w/ Thiel Powerpoint 1.2s Bedroom: Squeezebox BOOM Bathroom: Squeezebox Radio Around the House: SliMP3, SB1, SB2, SB3 Ford Thunderbird: Duet, Mac Mini Ford Expedition: SB Touch, USB drive ------------------------------------------------------------------------ iPhone's Profile: http://forums.slimdevices.com/member.php?userid=13622 View this thread: http://forums.slimdevices.com/showthread.php?t=86359 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
