what improvements would changing the opamps bring.
How much would it cost (parts only)
Any preferred brands

Sorry for the numerous newbie questions.

sir rpm,

my pioneer cdp (surplus) was modified by ferds, he basically replaced the opamps (he also installed sockets for the opamps so that replacing them would be easier, no soldering needed in the future  :) . a more detailed sound was achieved with the mod, as i have mentioned in the other thread i even had to lower the volume on my sub. i don't really know how much would it cost to mod a cdp because ferds did it for free (yes, free parts and home service!). hope this helps, cheers!

If you go for Burr Brown op-amps and your CDP uses 4, make sure to allocate Php 2k. The good ones that I've tried are the OPA2132, OPA2134, OPA2604 and OPA2107.

Even high end CDPs have constraints as far as budget goes so it is not necessarily true that all components use premium parts. Further, it also isn't necessarily true that using premium parts brings out the best sound. In this regard, replacing stock op-amps with better op-amps does not necessarily mean better sound. You really have to do some matching to find out which sounds best. I found out that through experience that replacing the differential, buffer and filter stage of the output op-amp section does not bring out the best sound. Using NE5532 at differential and good op-amps like OPA2604 brings out better results than fully replacing them with OPA2604.

Sa wakas na-mod ko rin ang aking Denon DCD-1650GL.. Nabili ko to for 3.5K sa laspinas sa tulong ni Jimbo..

Heto po ung ginawa kong modifications:

1. Replaced all the opamps with OPA2132, OPA2134 and LME49710
2. Removed/bypass output coupling caps
3. Replaced some caps with Sanyo Oscon caps and Panasonic FM caps - low ESR
4. Replaced the Lens with KSS-210A (original lens - KSS-150A)
5. Added IEC with Fuse power entry
6. Added lots of decoupling caps

future mods: Clock upgrade, Schottky diodes, replace regulators, tube output.. etc....

Please excuse my ignorance - but these all sound like rocket science to me :P
So, you guys basically change some innards of any cdp to make it sound/perform better? Sorry, as I'm not really adept into these things, but certainly would be interested to learn more :)

Consequently, I'm eyeing a Bnew Marantz cd5001 cdp which states that it has a Cirrus Logic CS4392 DAC 24-bit/192Khz and would like to ask the experts here of what possible "mods" could be done to this player & to what effects this will add to the cdp?
While I do intend to run out its warranty for a year first before even considering to have it modified, still would like to know more....you'll never know, baka mangati eh ;D

Any info would be greatly appreciated - thanks! ;)

Ang madaling i-modify e iyung output analog section. Puwedeng lagyan mo ng 8 pin DIP IC socket doon sa kinalalagyan ng DIP op-amp para tanggal kabit ka na lang -> Op-amps rolling ... puwedeng mong paglaruan mga iba't ibang klase eg OPA2132, OPA2107, OPA2604 etc etc. Bili ka ng mamahaling socket para hindi obvious na may ginawa ka.

Sana mayron tayong listening session para maka dinig naman kami ng "turbo" cdps    ::)

maybe some guys can bring their stock units to compare with the "tuned" versions para makita natin ang overall effect, kanya kanya na lang dala ng "mamam"  ;D

Unfortunately sir SOIC po ang mga opamps ng CD5001. http://www.diyaudio.com/forums/showthread.php?s=&threadid=74890&highlight=cd5001

The sound has improved a lot!

The high is not so sharp but silky soft.
Better stereo image.
More depth in the music (music fills the room).
There's more "punch" in the music. Probably because there's more depth.

Ooops, sorry. Hindi ko na-check kung ano gamit. Pasensya na.  ;D

Mahirap pala magkabit unless marunong ka ng desoldering technique sa SOIC.

dont worry bro pwdeng mod yan..   ;) di lang katulad ng ibang cdp na DIP or thru-hole ung mga opamps kya mdaling palitan.. kung gusto mo mod yan, meron ako tools dito for SMD soldering/desoldering.. and mga SMD opamps like OPA2107AU, AD8620, etc..

then compare natin sa mga cdp ko.. hehe

Kahit soldering iron, pwede ng pang desolder ng smd. Punuin mo lang ng tinga iyung magkaibang paa ng IC (pins 1 to 4 at pins 5 to 8). Then, initin mo iyung pins 1 to 4 then pins 5 to 8 alternately. After about 2 or 3 alternates itulak mo na iyung smd IC, maaalis na iyon. Same process for smd resistors and caps.
