IsoTek burn-in CD. It does the job very well! Load it and run it. You can find it here:
No one has (specifically) answered his question yet, and I'm curious to know this too: Is it necessary when burning in a DAC to have an output target device (preamp or amp) connected and turned on? Or can you just have the DAC connected with no cables connected at all and a signal loop feeding through it (via PC audio or Transport on "repeat")?
I was told that to put any drive or cd unit on repeat mode could cause your lense to wear faster because of some heat factors, so anny comments on that also reading copy could make the same issues ....
300-500 hours on a CD laser is a chunk of time. I don't know what the average MTBF of a CD laser is (nor if that statistic really means much). I don't think CD lasers are very powerful, and I'd wonder if they'd really generate much heat. Good question for someone who may know better than me. You can certainly weigh that against ripping the burn-in tracks to your computer and using the computer's hard drive to repeat the track over and over. Then you'd be using up your hard-drive's MTBF, of which 500 hours is a pretty small portion. I wonder though if tracking over the same passage for that long does inordinate wear to the drive. I doubt it. Of course it's such a small passage of data that it may just be playing it from RAM instead of the drive...hmmm...anyone?
