ADUM4160 can work with the CM6631 (plug device into iso, switch on iso, plug iso into PC) but it switches the driver into a slower speed so the device becomes limited to 96/24. I haven't managed to get it to work with CM6631A. (31A supports 176.4 but non_A doesn't)

Default Volume issues

Did anyone have volume problem with the USB variant.

Plug n play on Linux (alsa+mpd) works well but plays a lot less loud than my wm8741 dac

Maybe you can try an op amp on the output for small gain. AD8397 can drive headphones directly.

My mistake, forgot the alsamixer part where you set the volume for the device.
All is well now

Hi All,

Just a novice to DACs and had been looking at the various ebay cheapies and some lower end Fiio ones, though most of their models need an extra RCA/line adaptor.

Now found a link to this thread and the UAE23, which description was a bit confusing as it says Usb to Optical, though its seems the output connector is a jack that can be used as a line output at 2v - correct ?

Having read though all 28 pages of this thread it seems the UAE23+ model is perhaps the better model ?
Seems the advantages of the + are the volume control, RCA output sockets, isolation and external psu.
Wondered if you all agree the 23+ is the better option for a desktop system ?

Although not mentioned expect many of you are also now on W8 so wondered if there were and driver problems there ?

I'm looking to connect to an Arcam amplifier but it needs a 5 meter cable, so wondered what is the best way to do that, a long USB cable, long interconnect or 50/50 ?

Finally one for the EU guys, notice the HifimeDIY says they can post out from Belgium, but could not see any option to select in the checkout area, do they automatically send small orders out via the Belgium route ?

thanks

If only for desktop use, I would choose the UA23+. It is better for future tweaking if so desired.

The output is at a low impedance, so a long interconnect for the audio will not make any noticable difference. But then, this is DIY. Try either way and let us know your results.

For portable laptop use, the UA23 is so convenient. In fact, I would have both, as the price is so small.

I have ordered a second UA23 to the UK a couple of months ago directly from Hfimediy. It was first shipped to Switzerland, then to the UK. Hfimediy choose this route.

Hi,

Thanks for the reply, looks like its the 23+ for me then.

Interested to know if you had any import duty/vat to pay and how much the Royal Mail added on, partic as Switzerland is not in the EU so think like from the Far East anything over 18 is liable for duty ? or were you lucky and it came though ok ..

The UK customs people have never charged me import duty for anything I have ordered from out of the UK. I have not made any purchases for more than 50. For low value items, they do not seem to bother. I have done over a dozen out of UK purchases-- never had a problem.

Default Getting rid of the pot in UAE23+

If I desolder the pot, does anyone know which sets of points I should short to provide a set of bypass for the L/R signals?

Use an ohmmeter to see which of the three wires connected to each channel of the pot is connected directly to signal ground. Ignore that one and join the other two :-)
