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.

Here's the management design cycle of a product:
1. Manager starts new project and pushes engineers to develop the product on time and on budget.
2. Manager transfers to a new project before the testing is completed which will require redesigns and cost increases.
3. New manager takes over the project and pressures engineers and manufacturing to reduce costs in the design, the parts and the manufacturing process. Manufacturing is outsourced overseas to maximize profitability.
4. Manager transfers to a new project before the warranty costs start coming in .
5. New manager takes over the project and pressures engineers and manufacturing to improve quality of the product without adding cost.
6. Product sales drop off due to poor reputation. Management starts the product design cycle over using the previous bad design as the starting point.

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.
