Sorry if this is OT from the original post, but there are some great DAC related discussions going on in here. Still in planning stages of DAC purchase with sights set on Yggy but in case that option takes too long, I'm thinking about the Vega as an alternative.
Started thinking about this arrangement based on information released re the PS Audio Directstream and DSD - I guess I'm trying to 'emulate'/achieve some of the features in more expensive DACs with the following:
- Increasing sampling rate to push noise further into the ultrasonic band and with the use of the Mode 5 filter in the Vega (-3 dB @ 70 kHz) I should be able to preserve more original high frequency content. As an example, EMMDAC2X up samples all music to DSD128 in hardware prior to conversion. Also the Directstream LPF is apparently -3 dB @ 80 kHz (link).
- Bypass the PCM-to-DSD decoder in the ES9018 chip by transcoding in the PC. There are some thoughts that the integrated PCM decoder may be detrimental to sound quality.
- Hopefully run the Vega in EXACT clock mode to minimise jitter.
That's what I would do if I owned the Vega. Though I didn't think there was a difference between 2x DSD and regular DSD. When I had the Vega in my possession, I ran it via JRMC19 and upsampled all Red Book to DSD to feed the Vega over DoP. As indicated, I got excellent results with EXACT mode, although a good USB connection will be necessary for that. My PC worked fine in EXACT mode. My two laptops did not.
Make sure you'll like the sound of the Vega. (I expect the Yggy to have a very different type of sound.) It does tend toward the brighter analytical side. The other two ninjas weren't fond of it. One ninja used an Anax modded HD800. He initially liked the Vega quite a bit, but felt that the brightness eventually wore on him. The other who uses the Paradox or other variants felt it was "tolerable" in terms of the treble, but didn't say much else. I probably liked it the most, but I also happen to run speakers two-thirds of the time.

Just an assumption, and if it's not, it would probably have that kind of sound. I've spoke to Mike Moffatt a few times to try to wring information from him, but he only give hints like "they don't use delta-sigma chips for medical or military".
For all we know, they could be doing something crazy by making discrete resistor ladders.
