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.
Back in over 20 years, I own a pair of Celestion SL6 speaker. It was a very difficult load speaker and not many power amplifier can drive it well. I have Quad 405 at that time but this speaker is still hungry for power! In the last few years, I use this speaker as my test speaker when I build my amplifiers. This is the only picture that I have left for this speaker.
Even my pair of Celestion SL6 is gone, my brother still keep a pair of SL6si.
