Yes, but then you are also comparing 200ps jitter with 15ps . Also , the oversampling won't be the same either. You should compare with 88.2 / or 96khz source format. So , oversampling differences are rendered insignificant.

15 loops means theres no noticable degradation caused by the ASRC chip, as some journalists predict that the jitter / amplitude tradeoff is inevitably wrong.

That trade-off is already swamped by the noise shaper in the sigma delta chip , I beleive.

1: Quite true, of course. But just how "bad" is it? Perfect it is not, but nothing is.
2: For normal I2S, OK. But I was wondering if the "TG-Link" is buffered or level shifted or impedance matched or something for longer lines. I remember reading that somewhere, but could be wrong. There isn't a lot of info on it.

Don't get me wrong, I think async is great, just wondering about other ways of getting the clock there. I've spent 25 years running computer graphic signals over long lines. Clock (sync) issues become very obvious there.
There are many ways to deal with that, some good, some bad.

Well, this is old now, these USB thingies are here to stay. Now if you need 100meter and 50channels worth of 96/24 thats another story, its called IEEE 1394 ( FW) . If latency was no concern i'd prefer wireless.

[Pano]

Is latency a problem - in a home hi-fi system?

If video is to be synced, possibly.

OK, cool. Wasn't thinking HT, just music.

Yes, but then you are also comparing 200ps jitter with 15ps .

correctly do experiments I can, so if I say that this is so then it is so, jitter in both cases was the same as the rest.

You should compare with 88.2 / or 96khz source format

not intresting, nowadays intresting is only 16/44.1, with 96/192 deterioration in the sound will be less but will still be large enough (bad DF`s :-()

PC->DAC was the Missing Link for my DAC project for over a year. I couldn’t find it so I joined forces with a couple of friends to build it. My USB to I2S design is about to be released. It is an 8-channel Asynchronous USB to I2S interface. It works with ES9018. Please have a look: http://www.diyaudio.com/forums/digit...interface.html

Any feedback is highly appreciated.
