    Hi Wijnand

    Well there was two power supplies. The LPS for the Oppo mainboard itself was a custom one built by a guy called Coris on the DIY audio forums. I had 3 different variants of his supplies and they got better and better. Before that I used various LPS’s by oppomod.com which were also very good but not as good as Coris.

    But for the SAW clock itself I ended up with a Terra Firma power supply by JLTi Custom Analogue, it uses Schumann resonance or some kind of audio black magic. Anyway its unique.

    I used to do clock mods to my Oppo, used as a pure digital transport. I had tried about 6 different clocks, TCXO and OCXO clocks. Interestingly the best clock of them all was a SAW clock (surface acoustic wave). I have never seen anyone in all of audio talk about this clock or consider its use for audio, except for a crazy Danish guy living in Australia, Joe Rasmussen. But it was better than the -130db OCXO I had custom manufactured from RFX.

    In all my experiments with clock upgrades, and network tweaking, I have found the same thing as Wijnand, that the system can go ‘dead’ after a period of time, days, if not hours, depending on the configuration.

    I always put this down to electrostatic build up. But maybe it was clock syncro issue? And when I think about it, there is like 5 clocks all within 2 feet of each other on the rack, and all these clocks are not mu-metal shielded like some high end components have, just exposed to one another.

    Maybe this is an issue to be looked at?
