    Musiland 01USD, Teralink X, Teralink X2, all have optical out...and probably many more do too....so do some reading at this site to find what you want.

    Teradak Teralink-X2 released 19.1.10

    Have you got any noise specs ? This is my main concern (considering the reg is after a battery and the X2 presents a constant load). EDIT : Flea looks great for noise but it'll only do the xo, not the whole X2 as it is 30mA. http://www.pinkfishmedia.net/forum/s...ad.php?t=21940 Tentlabs...

    Teradak Teralink-X2 released 19.1.10

    Hi guys, I've got the day off so I've been playing with the X2. Resampling works, (although the effect isn't as strong as with the pcm2706), so thanks again to all who pointed me this way ! It helps my dac too (Modified Musiland MD-10) cos that loves 96Khz. Resampling also seems to create...

    Onkyo SE200PCI-LTD or Asus Xonar Essence ST?

    VLSC is a feedback circuit, and requires 10 op amp channels in use instead of the normal 6. I don't think it degrades the sound unless the op amps are junk or the caps and res in the circuit are nasty. All op amp circuits use feedback. I've done something similar to this and I wouldn't say it...

    Onkyo SE200PCI-LTD or Asus Xonar Essence ST?

    Yeah, almost too many right ? I guess the market for high quality sound cards must be pretty huge these days. Maybe one day soon we'll get something truly no compromise audiophile....a completely enclosed, independently powered, ASRC, fully balanced dual mono DAC with class-a head amp....

    Onkyo SE200PCI-LTD or Asus Xonar Essence ST?

    I have only listened to the Onkyo and Asus. It looks like you've gone all out on your rig so it seems to me you'll want to toy with the sound card a little ? If you're happy just to swap op amps then get the ST. If you don't like it, maybe you can return it ? If you don't care about warranty and...

    Teradak Teralink-X2 released 19.1.10

    I'm gonna give the software resampling a go. I have a couple of usb devices that have pcm2706/7 chips and cheap 12.000Mhz crystals, so it'll be interesting to see if they can be improved and, of course, this X2. I'm using the latest Foobar and there seems to be a consensus that the best...

    Gamma-2 (γ2) DAC Thread

    Hi Ti, Can I ask you about the y1 ? The CS8416 datasheet suggests this RFLT CFLT CRIP 23kΩ 22nF 1nF On the y1 the components are C18D, C19D and R4; 3kΩ 33nF 1nF So I'm curious about the filter change from the one given in the datasheet....and what would be the effect on jitter of...

    Awesome xo - is it running off a regulated battery ? Or is the blue thing a trans and rectifier ? Current consumption of my X2 with external psu was under 100mA.

    Asus Essence ST - fully modified ?

    Hi, I'm quite willing to believe that removing the original Nichicon would have a more noticeable effect than the smaller steps I took to get there, so I've probably placed it too low, but nevermind...... But for me, definitely that Vanguard tcxo had the most effect. I don't there is...

    Teradak Teralink-X2 released 19.1.10

    Two weeks is about right - you should get it any day now.... I think I've found an upgrade for the 3.3V reg. It has similar specs but much lower noise; just 40uV noise as opposed to 100uV. Of course, they could have been measured differently..... The DCY package is sot-223 4-pin but they...

    Asus Essence ST - fully modified ?

    Hi, It's exactly why I started this thread - because there are too many posts to find anything; I can't. So I dunno how anyone is going to find out what and how to do it. Just IMO here is my preference for mods in order of sq improvement : 1) Replace xo - reasonably easy; hardest thing...

    Asus Essence ST - fully modified ?

    Come on, $20 is not that much for a great op amp. It's the price of Bursons etc that I find outrageous. Besides, LT agreed to send me samples and simply haven't, and the samples I wanted were US$2, not $20. So I'm not keen on buying their products now. However, the LT1028acn8 are about US$14...
