life expectancy of a cdp?


I am looking at a used Parasound cdp. I know that it is based on amount of use , but on average how long should a unit last, and what amount of maintance is required? I read in other threats about the laser having to be serviced in some units.

Several users of the Audio Aero Prima with Philips transports report problems. I have read of no problems with the same player utilizing the Sony transport.

It seems there is no completely reliable manufacturer.

Anyone know who makes the laser assembly for the Denon 3910? I've gone through two. The second was installed just six weeks ago, and it's beginning not to read some RBCDs. Real POS.

OK, now I see where you're coming from, Grant. Yes, we're saying the same thing. Previously, the Philips units were inferior to Sony. The Audio Aero Primas with the Philips part were really bad. Now, it's the other way around - I have very little confidence in the Sonys from the past couple of years.
I know from talking to service guys that a problem that drives 'em crazy is getting a unit in for service ( disc skiping,won't read -whatever) and realizing that it's the same mechanism they are already familiar with on a hate and despise basis from other co.'s products. DVD recorders suffered from this bigtime a year or so ago - apparently almost everyone bought their laser plus spin n tray from the same OEM in Taiwan (Funai) - none of 'em worked.
Frankly - from my point of view - the major problem is that CDP's last too long - people are still playing what were once pretty good for the time players - better and cheaper things have come along since and they just won't give up on that 20 year old treasure.
