Denon DCD-810 tweaking
A college gave me a Denon DCD-810 which wasn't reading cd's anymore. After replacing the KS-152 head with a KS-220 head, I got it back working flawlessly.
I gave a look at the components inside, I found (after the CD dedicated circuitry) :
- a SM5807 fold oversampling filter
- a pair of PCM56P DAC (one of each channel... not the 1 DAC and analog demultiplexing on two channels scheme)
- 3 M5218P op-amps
I'm considering tweaking a little bit by changing the op-amp I suspect to be some kind of low range devices (datasheet of the M5218P is attached) : datasheet says "has virtually the same characteristics than 741 opamps".
Among the classics, I found the NE5534 which may fit (same package and pinout).
Does anybody had some experiences with those M5218P ? Which replacement could be suitable/interesting for those (other than the NE5534) ?
Thanks in advance,
