RE: Juli@ Follies...




2nd update... first, the breakin continues, but I have a tale to tell about it.

After the upgraded Juli@ had been running about a week, I was not happy with the sound. It was muffled and confused sounding. Not what I'd expect from a sprinkling of Black Gates. So I swapped out the modified Juli@ for my un-modified control... no joy, still sounding muffled and confused.

Oh, I remember, a few days after tweaking the Juli@, I decided it was time to finally replace the Holco series Rs in my stepped shunt attenuater with those nude Vishay's I'd had around since last summer. Could the Vishay's be bad? No, they weren't, but when I looked at it, I saw solder joints that weren't pretty. I guess I was tired when I made those joints. So I cleaned the solder off and resoldered... and the magic was back.

The sound of the modified Juli@ after two weeks of burn-in builds on the early strength of a competently & confidently served wealth of details (adding a lot of texture and 'dense-ness' to the sound) and adds an even quieter background, stronger dynamics, stronger deep bass, very well-defined and natural trebles, and a much-improved ability to handle complexity with aplomb.

IF you were building a cMP setup and didn't have a separate DAC, the stock Juli@'s analog outputs by themselves are not bad after being fully burned in... and this modification takes it to a whole new level.

Next there's powering the Juli@ from power separate from the motherboard. Danged, Alfred beat me to it for the 3.3v on the digital card, but I did get a full-house power supply built for just this purpose today (see attached picture).

It's a tweak-ish supply... no magnetic hardware, MSR860 diodes, Jensen 4-pole caps, Dexa regulators for the +-12v, 5v, & 3.3v, and minimal wiring. With a little time-management tomorrow, I may be able to cut the PCI power fingers and wire it in.

I'll keep you posted.
