After reading your post I read further on line and it sounds like it was/is a great cd transport. I have been trying to figure out dates of production and guessing by serial number if it was an early or later production model. Don't the lasers go at some point? Would a later model ( mid 2000s?) likely last longer than an early production model? If the laser goes are there places to fix it? Because, after reading on line, it seems like an excellent solution to my problem, except for my concern of the life expectancy of the laser. Norm

I have no idea about laser life and have the same concerns as you. But I know 3 people w/ these and they are working like new so far.
I can never go back to a bad transport, so if/when this fails if it can't be repaired, then maybe I find another one or get a $700 transport?
I would be more concerned about moving parts than a laser though.
My other friends are using Bifrost DACs, BTW.BTW, I always found it strange that I did not hear much difference in sound quality between satellite radio and CDs (from Oppo). Now, there is a big difference between radio and discs. When I had the Gungnir DAC to try it locked on both radio and Oppo as having tight clocks, so jitter is not the weak point of the Oppo (or radio), it seems to me. There are other aspects that are very important in a transport, which I do not know.

Any stock Oppo is simply a catch-all spinner. Additionally, it has a nice DAC for computer audio applications.
It must be "modded" to go to the next musical level.
CD player laser life from around this era (late 90s to early naughties)was typically quoted as circa.10,000 hours. However what I don't know is if that is to zero output. If so a laser would cease to have sufficient power to read discs well before this point was reached especially those designed for hybrid SACD.
BTW, the only transports that I have had that needed laser replacement were from the Sony 333/555/777 ES series (all use basically the same device).
I hope the S7000 ones are better, because that's only 1.5 years if the player is left on, unless it turns off the laser after some idle time.
I leave my "transport" powered on since it sounds a little better that way (after ~40 hours on, it changes from having minor glare to no glare).
I also used to leave my Oppo on when I used its analog outputs because it took ~5 days to sound its best. But now I leave my Oppo off since it has become a secondary source (for movies only).
Don't worry on the point that you raise. The laser only switches on when you insert a disc (to read TOC) and then when you press play.
In many players it is essential to leave the machine on particularly those that use resistor ladders to set the voltage values in the DAC as thermal stability is required. Pertinent here as this is, in part, a thread about vintage players where such technology is common.
