There's a review of those USB couplers at the bottom of this page: http://www.enjoythemusic.com/magazine/equipment/0412/usb_dac_shootout.htm

 

As expected, they sound great! But using USB and RCA couplers together seems unachievable and I'd rather have an async data flow through a USB cable than a passive S/PDIF coax cable.

It´s only a question of time something similar is available at sub-10 euro prices (like the Tenor chips used in many cheaper converters). The early adapters always have to pay extra, just the way it goes.

 

Having owned the DI and HiFace, I can recommend the DI. It´s clearly superior, and more versatile as well. My friend who has the stock HiFace EVO feels the DI is at least as good as it is. 



I agree, they are expensive... have you or anybody else had the chance to compare the U3 to the DI, or to the Mhdt Lab, or even to the XMOS board (http://www.xmos.com/products/development-kits/usbaudio2)? 

Maybe I can put the XMOS board in a box and save $300.

The eval board is most likely using high ppm clocks. Good clocks, a nice enclosure, RMA and resellers markups double/triple the price. DIY is always cheaper.

Hello guys,

 

I have just finished to review the Stello box, pretty amazing stuff in the overall even if components are not killer ones ...

 

if you wish to read: http://musiq-audiophile.blogspot.fr/2012/04/stello-u3-english-version.html

 

My personal feeling regarding cables is that, depending on the USB cable, the result is different. It is true that when power supply runs close to data the result is not very good and that those who separate data from power give better result, but as a matter of fact, I also experience that depending on the cable builiding on the data side, the result can be improved. This is a bit disappointing that new generation of USB processors does not handle this problem a better way than before... :(

Hi,

I review ART Legato, U3 and Halide Bridge (sorry, in Russian)

http://soundex.ru/index.php?showtopic=34164

 

ART Legato is the best, but U3 is so close and convenient that I choose it over rest two.

That's the one, yes. I also like this one but you'll need a DAC w/ a BNC input obviously: http://www.ebay.com/itm/220676728464

Still undecide between U3 and AP2, though.

Is it possible to get a rca male-male adapter with 90 degree angle? That way I could point my Hiface Two in the direction of my PC.

I received U3 for testing yesterday. Initial impressions are very positive. Very revealing and transparent sound. What I wish is maybe slightly more forgiving top end. It's very revealing at the moment, I'm not sure if it gets smoother while burn in. I guess the unit which I got is brand new. 

 

I have one question. I use the device with Naim DAC and I have Naim DC1 digital cable (BNC-BNC). So naturally I want to use BNC input on Naim DAC. Now I have a simple BNC female to RCA male adapter which I use with U3 RCA output. Is this solution better than to buy AES to BNC adapter? They're quite expensive, for example a Neutrik one costs almost $50.

I also have Audio GD DI-DSP at the moment but it's suffering of driver issues on win7 64bit. I hope they get it fixed soon.
