One of my projects
Hi All,
I thought somebody might be interested in one of my projects. It’s a Playstation PS1 modded to be a kick ass CD player. A friend exhibited one in an audio show and in blind tests, it beat a £10k machine. I couldn’t resist building one. The theory is that the PS1 has a simple yet great DAC with low jitter. All that was needed was to build a twin linear power supply and to bypass everything after the DAC and add a pair of high quality coupling caps. It’s a voltage out DAC so just needs a bit of oomph to make it work. The opamps were replaced by a buffer stage giving roughly 1.5 gain using either a 6080 valve or a Russian 6H5C (My favourite for rock music). I’ve found that the Tube buffer really improves the sound from my Raspberry Pi/ Dac streamer too. I’ve done quite a few other mods now but I’ll bore you another time with those
