Sony CDP-222ESD tweaking
 
Hello Everybody :)

I'm a newbee, and this is my first post on the board, so go easy on me... :D

I own aforementoned player, and was wondering what further tweaks can I apply on it.
So far, I have removed the mute transistors, rolled the op-amps (used op275 and ad826), exchanged the power cord, isolated the crystal from vibration (unsoldered it, isolated with foam, and then attached to the PCB via two very flexible wires)...

The player gained in soundstage widh and depth and overall speed and clarity...

What more can I do?

Cheers....

P.S. I would be thankfull if somebody who has it, would email the

Thx Bernhard :)

Nobody else? :(

OK, here are the pictures of the player's insides, and an hi-res picture of it's PCB...

It is intresting that I cannot find much info on this player on the net except it's manifacturing date (1987). Wasn't too popular in it's time? :rolleyes:

Its made around the TDA 1541 DAC, like it's bigger brother (the 333ESD) wich was going for 1000+ Eur (modified) when I bought mine for 150 Eur (3-4 years ago) :dead: Do they share some parts or simular construction?

Anybody got any idea what more can I do with it?

Cheers...

P.S. On the hi-res picture of the PCB, you can see the topology and the symbols on the PCB and elements if it's any help....

P.P.S. Nobody has the service manual? :(

222ES
 
God I used to own one of those but gave it to a friend in need about 5 years ago, It served me well for 12 years the only fault being a slipping tray drive belt. It was a pretty nice sounding player to if memory serves me correctly. Im now listening to a heavily modded XB770 @ the mo. you can see some of the mods done to this on my website www.extreme-x.co.uk

THX Chris,

Can you just clarify wich model was your former player (because in the title of your responce you wrote 222ES , and this model is 222ESD), just to see are we talking about the same player :D

This is one other thing that's a puzzle to me...

What does ESD stand for, or how much diferent is the ESD version diferent from the ES version of the player? :xeye:

I was able to find a lot info on 222ES on the net, and it seems that it's made around PCM56P J DAC.
Is that one better sounding than TDA 1541? (damn you Sony and your hundred variations of the markings :D )

If somebody else's got an idea feel free to join the discussion ;)

And, if some kind soul has the service manual for my player, please send it? (I'm geting reeaallyy boring with this, am I? :D )

Cheers...

IMHO the D stands for digital out.

IMHO some PCM56 are better than TDA1541/A but some S1 or S2 might be as good.

IMHO DAC chips need to be selected by end user.

Did you mean that I should put a steel "cover" over the transport?

Where can I (commonly) find glavanized steel?

Can you post a picture of the tweak, so I can have a better preview?

THX
