PIONEER PD-65 Schematic??

bear · 8th August 2005, 01:48 PM

Anyone out there got one??

I'd like to look at it to try to figure out why the thing sounds tipped up on the top end - both digital out and analog!

I believe that you can buy the schematics from Pioneer USA.

Not sure by what you meant by "sounds tipped up".

The PD65 is a nice player. Should sound better after a good mod.

"tipped up" = too bright and zingy on the top end. Not natural sounding at all. Characteristic of all the Sony & Pioneer pieces I have ever heard.

I know I can *buy* it from Pie-on-ear, but I'd rather just get a simple pdf file or a photocopy/hardcopy rather than forking over way too much for their originial, if I can...

The purpose of looking at the schematic is to see what they are doing in the digital side that *might* be causing this effect, since it is noticeable on both the digital out and the analog out.

Nasty sounding player. Very adjustment sensitive. Trash it ASAP.

Before you trash the PD65, try modding it a bit. It can sound quite nice actually.

I own the PD41 (PD65 without Legato Link) and it is very well-built.

The components like caps are very old and are probably non-audiophile grade caps. The player should benefit from a comprehensive caps upgrade.

For starters, to remove the tipped up sound, just replaced the coupling cap at the output with a Silmic or Blackgate NX.
