Hehe imo it does not look promising it looks like a 5$ wall adapter (sorry) and it cost OMG 98€...

Yes the price is horrible but IMO it's quite an interesting design. You can add it to pretty much any device.

I might eventually have to get one to try with the V-Link 192 I have on order (uses the XMOS chip, too). It looks incredibly cheap, but its ripple spec beats what Kingwa claims his PSU will do and that's really what matters.

Thanks for 1.43 upgrade suggestion, lee. I'm not sure if I imagined it, but this updated driver seemed maybe a full db louder on the output. Is that even possible?

 

I'm also using the Lacie flat cable recommendation. I think I'm going to experience more with usb cables in the future but right now it's a keeper. Thanks again.

Anybody know if  usb_audio_110907 is still latest firmware update?

You're most welcome, I also agree that the 1.43 drivers sound better IME. At least they support bit-transparent 32bit ASIO, that was introduced in 1.33: http://pastebin.com/jatqjVP6

 

Any driver >1.44 requires a firmware upgrade, but I see that many/most companies selling XMOS based gear can't be bothered to release firmware updates either. The Anedio U2 is much newer than the Stello U3 and yet ships with 1.22, and so did the new Micromega DAC a few weeks ago....luckily we can use the 1.43 of the DacMagic+ so no big deal happy_face1.gif

I hadn't thought about firmware updates for the D2. Do those xmos updates work on the U2/D2?

The latest from their site is all we have.

You will brick your XMOS receiver if you flash an incompatible firmware. Using the 1.43 DacMagic+ drivers on the U2 if it comes with the 1.22 is your only option, I posted instructions on how to do this in the previous pages wink_face.gif

Hey guys,

 

I have a Viablue coupler for sale (Lacie cable too). I thought somebody reading this thread might be interested.

 

It won't work with my Burson DAC. Never even got to hear it.

maybe you could install the U3 vertically or diagonally, et voilà happy_face1.gif

post #161 of 279

Nah, it's just not going to work. Gotta go with a coax cable.

That's totally ok though. I'd rather make somebody else happy.

 

I'm in awe of the sound right now (and that's with the $6 Lacie.)

Currently listening to the Stones - Let it Bleed. 

WOW.

Just to let you know, I've contacted April Music about the driver update, twice actually. They said they're working on a new driver but it takes time. It's been months since I contacted them so I have no idea when they'll release the new drivers and how will they inform us about them. Do we just have to download the driver package from U3 website and try out or what.

Good news! It will require a firmware upgrade, which is most likely the reason why it's taking them time to work out.

I've just gone back to 1.43 after an extensive period of using 1.22 and I agree it sounds better!  (It's like a breath of fresh air using JPLAY and Ulilith 32 bit int).  

 

Mr Perry, are you ever going to divulge how to do the mod of connecting a linear P/S to a usb cable for the Eximus DP-1? smile.gif
