Burson has not publically stated the USB transfer mode on the 160D in their specs page.
They made no attempt to correct the description posted and used in multiple ads by 6moons.
http://www.6moons.com/audioreviews/burson5/5.html (still in the conclusion even after numerous emails, and them removing the ad...f-g appalling)
http://www.6moons.com/showcase/burson/burson.html (used to have async usb in read, was a showcase ad, now removed by 6moons after this thread has been started)
Everywhere it says it's asynch. It's not, it's a TE7022L and adaptive. And burson definitely know it/read the review/etc. Moreover, Burson link to their review on their product page. http://www.bursonaudio.com/HA_160D.html (juuust below the menu)
Burson have also potentially being less than honest with this:
I e-mailed Burson directly before hand and confirmed it is supposed to be 24/96 asynchronous. I have been attempting to trouble shoot whether or not it is my system or not. I really wish another person with the 160D and a Mac was present.
As I said I contacted Burson about this issue and they have been extremely responsive. Apparently I am the first person reporting this experience (though I may be the first person who has OS X, a 160D, and tinkers with USB Prober .
I am working on it with them and will let you all know how it resolves itself, thus far I am quite satisfied with the responsiveness and friendliness of the Burson guys. Too bad they are in Australia .
I checked with Burson.The 160d uses adaptive transfer which is kind of a hybrid between synchronous and asynchronous.
At the end of the day, what matters most is how it sounds. It sounds great. My only complaint with usb was lack of 88.2 support, and i have a moderate amount of 88.2 source.
For this reason I use coax instead of because it gives me more sample rate options, but I didn't particularly notice a change in sound making that switch. The coax interfacenhas a 10pps clock.
Couldn't resist. Either Burson and 6moons mislead us, or myinitialsaredac told us it was async without checking.
PMed myinitialsaredac, he says:
I was mislead, in the earlier literature (when I bought mine) the selling companies and Burson informed me that it was indeed asynchronous.
I have checked with usb logger and it is an adaptive endpoint.
and I believe him.
The adaptive transfer mode spec is confirmed by Moon Audio. http://www.head-fi.org/forum/thread/523568/burson-audio-ha-160d-headphone-amp-dac-preamp-new-product-alert#post_7364430 as well
See, I would've left this alone, but I feel burson and 6moons have behaved very poorly. Moreover, 6moons keeps saying 160D is async in its recent reviews and make pretty ads with async in red.
The original debate about this has been buried by fanboys in the 160D thread, so I thought I'd make it a separate thread, after I double checked with the parties involved.
6moons and burson have declined to comment for weeks now (aww, ignored) and new reviews and ads with incorrect facts continuing to crop up on 6moons.
Hopefully this makes them cease bsing and issue a correction.
