Default Components in my CD player - good or bad?

I have checked my Vincent CD-S3 CD player in order to see if there are any components that badly needs replacing.

Can anyone say how good or bad the following components are:

OP-amps:
After the DA converter is a OPA2134 - a double op amp
After that a NE5532 double op amp per channel
Then an OPA2604 double op per channel
By the balanced outputs one more OPA2134

Voltage regulators:
One LM317T overf by the clock
An A1837 at the D/A omvandlaren (is this a voltage reg?)
A LM317T at the analog part

The clock is built with an oscillator, a 74HC74 flip-flop and a 74HC125 buffer chip.

I would very much appriciate any help!
