CD-PRO2 Transport

Monday, May 12th, 2008

This is a transport using CD-PRO2 module with a China controller kit.  The digital out from the module is further re-data using a flip-flop with a XO about 100MHz. Then the digital signal will pass through 74HCU04 buffer and output to Optical, SPDIF and AES format.

Denon DVD-3800 modification

Friday, June 7th, 2002

I once owned a Denon DVD-3800 and I had modified the output with a transformer Lundahl 1527 to couple the analogy signal.  This proven that transformer only change the sonic a bit but cannot improve the overall performance!  This is something like changing a signal cable or a socket.

This was my first CD Player back in 198X period.  This is a 20bit machine using PCM64P, NE5532 and NE5534.  I have done a lot of tweaking on this CD player until the laser head is too old to play CD.  See the record of my tweak in the photos.
