Does any of you have experience with upgrading a marantz cd94mkII?
It's an old cd player with 2 TDA1541A Single crown's in deferential mode and 4x upsampling, but with a lot of NE5534 behind the dac's.
I have the folowing options:
- make it a NOS dac by deleting the upsampling.
- make the dac's parallel. So 2 TDA1541 single crown parallel.
- straight from the DAC to a single FET like the http://www.lampizator.eu/LAMPIZATOR/FETISHIZATOR/fetishizator.html and direct to the output.
I like this solution because it's very simple.
Or must i use some different kind of I/V conversion?
I think a discrete output will be better than opamps.
Reading DiyAudio is lots of different possibilities, but wich is best for me?
Regards
Ronald

Boky,
i did search and found your topic about the 94mkII.
But.. there is nothing about a discrete analogue output. You use opamps, i will not.
There is nothing about making the DAC parallel and NOS.
I also found http://www.diyaudio.com/forums/showthread.php?postid=1719109#post1719109
wich does parallel dac's and NOS and use analogue output. But in some different situations.
I believe the changes to NOS, parallel and analogue output wil have more input on the sound than the changes you made. (at least i hope it will...)

Ronrhe,
You have many choices :
HDAM - designed by philips and used by marantz in their top players = they do it in china - replication 90 $ us
= you just buy the module and plug it to the TDA output : it amplifies and buffer the signal and filter high frequency.
Build your own output/filter stage
Build the one of monica2 ( cant remember the name)
Build a tube output
Use any preamp with modification / aikido / etc
