What would be really cool is if a company like Wheatstone started a line of good, basic CD players. You'd never have to worry about support, repair and parts.
(yes, I'm a bit of a Wheatstone fanboy

)
I think we need to go back to basics here and re-invent the CD player. The words "basic" and "long-lasting" just don't seem to go together.
The biggest issues that I am aware of with CD players are:
Cheap transport mechs including spindle motors and spindle bearings (if they even use them).
Poor laser longevity
Cheap loading mechs.
The best spindle motor I have seen in a CD player is one that Technics made - in the SL-P990. It is basically a three phase motor that uses a magnetic rotor with a fixed stator. Having no brushes, a motor like this could theoretically last forever. What seemed to let them down however were the SMD capacitors they used on the stator board. They tended to leak electrolyte all over the PCB after a number of years, which did awful things to the copper tracks.
Tascam used a similar motor in their 122 MkII cassette deck, and it had the same capacitor issues.
Mechanically, a motor like this, coupled with high quality roller bearings would give years of service. However, the cost is significantly more than a cheap, mass-produced Mabuchi motor from China, which is probably made for about 10 cents.
Next comes the laser diode. Can't find a lot of information on life-expectancy, but then it must be remembered that the performance of a CD player will drop markedly long before the laser diode is totally shot.
As the output of the diode starts to fall, the received RF level drops below the threshold required for optimal playback. Whilst there is some compensation in the circuitry, eventually it gets to the point where the machine will refuse to play or even read the TOC despite the fact that the laser is still operational.
I don't doubt that laser diodes can be manufactured that last for many years. They probably use them in the military for guidance systems and other such uses. Cost of said components would be outrageous too! So, we have a non-mechanical part, but one that still "wears out".
Finally - loading mechs. The majority of CD players have motorised loading trays. These don't give huge problems although after a while the belts stretch and the drawer either refuses to open or close. A new belt will fix the problem. The motors don't seem to give a lot of trouble - then again their duty cycle is very low. I think Denon were on the right track with the DN-961FA and its manually operated loading tray. No fancy motors or gears or belts to give trouble - a spring-loaded opening system, and user assisted closing. Simple, effective, cheap.
In most cases the electronics long outlasts the mechanicals of a CD player. So they aren't an issue. Providing they've been designed properly however, and good quality components have been used.
The upshot of this whole saga is that if someone decided to make a quality CD player with a multi-phase spindle motor, roller bearings, a manual loading mechanism and a laser block straight from the military, it would probably last for 10 years plus - even if it was used every day all day. The cost of such a player - well, it could possibly be more than one of those esoteric, high-end audiophile machines that have valves glowing in the front panel and look like something out of a Star Trek movie.
Would you buy one?
