Open it in photo editing software like Paint Shop Pro or Photoshop (or similar) and save it as a JPEG; increase the compression until the filesize is under 100Kb.

I'm useless at describing sound perceptions!

Generally just an overall increase in the detail. With Lambchop ("is a woman" cd) there's a greater sense of separation between the different instruments (especially in quiet passages).
I'll leave the descriptive part there, before I sound even more of an audio luvvy.

In fact, I've only connected the clock to the psu at present. When I added the second set of diodes etc. to seperate the secondaries, to also feed the dac, I found that one of the secondaries was faulty (I think I drilled into the tx when drilling the fixing mounts in the pcb!). So maybe some more improvement to come when I get a replacement tx.

Pete

Hi Ray,
3 days ago I fitted +12V/-12V Raygulator on small pcb with independent new PSU (1Amp 12 VAC....= 12VA ???).
The regs inject to op amp via R651/R653, ground from regs going to star gnd (output RCA) via C653/654 and ground from psu wired to C801/C802.

Before fitted, I have checked output regs and got +11.96V and -11.68V, but after sitted in the CDP I got ((+9.69 V), (-11.67V), standby mode) and ((+9.60V), (-11.67V), running mode), what happened??....(raw DC supply from new psu (+16.10VDC), (-15.96VDC)

After 10 hours 'break in' I have noted that sound more open, more smooth and more dinamic especially in the mid range area also more deep and weight bass but I don't yet satisfy with bass resolution, I need more. What can I do?, replace dioda with fast recovery ? (1N4937), release snubber circuit?,bypass caps tank in the new PSU? or replace + regs?, others?

Note: PSU with 2xBG 1000uF/35V, dioda (1N4007) and snubber.

Regards
aquar
