Sony CDP-315 Modifications and Upgrades

OK, so I also got a Sony CDP-315 single disc player and decided to try modding it. This one was much harder as It had a pair of SMD opamps and replacing them with a pair of 8 pin DIP sockets wasn't easy, but I managed to do it just fine.

So, here are the mods:

1. Installed 0.15uF X2 power filter cap
2. Intsalled a pair of ferrite chokes (on on power cord and another on the line out flat cable)
3. Replaced original opamps with NE5532 and later with Burr-Brown OPA2134 (2134s do sound better).
4. Replaced electrolytic coupling caps with a pair of Jantzens 4.7uF/630V.
5. Replaced RCAs connectors with gold plated ones.

The increase in performance was great too, but nos as good as my ONKYO DX-C380 CDP. I plan on replacing all supply and decoupling caps with Rubycon ZLs to improve it further.
