I assume that U3 will work with the isolator, just that it will lose the async feature???


Did you ever try BTW? The Musiland supports up to 24/96 through ADuM4160 AFAIK, OTOH the Hiface wouldn't work at all.

I have tried the Olimex on U3. The max output falls back to somewhere between 16-24bits and 44.1khz to 48khz. Can't remember the exact value.

 

It will still work though.

On a side note, I have been on a lookout for the LaCie USB cable for a long time. The cost of the cable (after factoring into shipment), costs USD40 which is quite ridiculous.

So it works after all, interesting =)

 

You can always bribe a US head-fi member to ship you one: http://www.google.com/products/catalog?q=lacie+usb+flat+cable&hl=en&um=1&ie=UTF-8&tbm=shop&cid=5550716588549145362#scoring=p

As much as the Lacie USB Flat Cable sounds great, we can easily guess that they didn't go overboard w/ shielding for this kind of price....I'm eagerly awaiting my copper EMI shielding tape, the goal being this kind of shielding: http://www.audioadvisor.com/prodinfo.asp?number=PGUSBPC

They seem to have shielded the power wires together, but I think I will shield the 4 wires individually, then keep them flat w/ several mm between them for insulation purposes evil_smiley.gif

BTW, seen on a local forum:

That's what I've been doing since day one, but he's also doing it w/ XLR:

That is a common thing to do with such devices.  Why use a cable if you can get away with a short adapter?

Male RCA to RCA, Male XLR to XLR...very common adapters.

Ever managed to try the Lacie Flat Cable then?

 

One thing that would be really sweet would be someone finding a way to hack I2S out of the U3, much like all the Musiland hacking that's been taking place on this blog for years: http://hifiduino.wordpress.com/2011/09/02/hifiduino-bii-musiland-in-japan/

 

And apparently the XMOS chipset is compatible w/ ADuM4160 at low sample rates, so that would become a pretty sweet solution for isolated I2S evil_smiley.gif

 

AES/EBU is just balanced S/PDIF, using one of those short adapters they should more or less sound identical. I2S is another ball park altogether.

BTW, NAD have the 1.55 Thesycon drivers available for download: http://nadelectronics.com/download-agree/120302080920-NAD-USB-Audio-Driver.zip|NAD%20USB%20Driver

 

The .inf editing explained in the previous pages works perfectly cool.gif

I recently received STELLO U3 connected with Wireworld Ultraviolet USB and MIT RCA Digital Reference to the Bryston DAC BDA1

trasfer data: Netbook i3 380M Win 7 64bit Fidelizer WASAPI Sox 4x, Sonnox VST for "micro" audio balance to my room (-3dB max adjustment).

 

Increeedible sound, very very realistic !

 

Step II

I'm waiting for USB 2.0 adaptor A male, B male and Apogee Wide Eye AES/EBU for setup comparison.

 

Step III

I want to try O.S. Voyager MPD.

but... I do not know how to get started without problems...

 

 

Advice, are welcome !

 

Joy!

you plan on daisy chaining the U3 to a netbook? that's gonna be very inconvenient, don't you think?

 

anyway, the 1.55 drivers from NAD are nice and all but they don't provide any control panel so you can't change the latency of the ASIO driver...and it seems to have been set very low.

Thank you Leoperry, for advice !
I try to plug directly the Stello to the DAC with XLR adapter into AES / EBU.
The Netbook is plugged with 1m USB Wireworld Ultraviolet to the STELLO.

I find a little more sweet and balanced sound with this solution.

I don't know about Nad driver 1.55 alternatives.
Where I can find them ?

Ps.: I don't like ASIO original Stello driver. WASAPI is better.
What do you think about ?

I've explained in the previous pages the modifications to make to get any newer driver made for another transport to work on the U3. I posted the link to the NAD drivers a few posts earlier in this page.

 

I've done more tests, the latency was set too low on the NAD 1.55 and there's no way to change it easily(maybe it could be done via the registry)...so back to the 1.43.3 from the DacMagic+, they work great on the U3 normal_smile%20.gif

 

Personally I prefer the SQ of the native ASIO drivers, but it's good that we can choose between WASAPI exclusive, KS, native ASIO and A4A(the worst sounding by far to my ears).

 

Yep, use a male/male XLR or RCA coupler together w/ a good USB cable(such as the 4ft Lacie) and you'll be good to go happy_face1.gif
