...and I dread to think what it might've done to the Aune if I had just plugged it in, without checking it first!

I had a question about the AUNE amp / DAC - it can't be used to power speakers can it? I was looking for an amp with an spdif input and speaker output - but it doesn't look like this fits the bill. Any advice much appreciated.

Any advice much appreciated. No, not ordinary speakers: it has no power amp so unless the speakers have volume-adjustable power amps built-in, the Aune Mini USB DAC won't work. The headphone output at the front is obviously unable to drive regular loudspeakers, and the RCA output at the rear is line-level and not adjusted by the Aune's volume control, so needs a separate amp and speakers.

Thanks JohnnyBlue, much appreciated - I guess I will have a look at the Topping TP30.

Hello all, I hope I'm not reiterating questions that have been asked before, I've had as much of a look through this thread and the rest of the forum as I can but I'm very new to the world of headphones and such like! Anyway, having read another thread on these forums I'm intending on purchasing a pair of AKG K601 headphones, and now I'm trying to find a suitable amp/DAC combo to run them. I was originally set on getting the Fiio E7/E9 combo as they were heavily recommended on headfi, but then I came across the Aune and now I'm not so sure. If I buy the Aune, will I likely have to buy another PSU in order to get the best quality? And is the Aune worth getting for someone like me who is wholly incapable of swapping out op-amps or anything complicated like that! The main advantages I can see over the Fiio combo is the SPDIF input, and the £25 price difference. So with that in mind, could anyone offer me any advice? This is all very confusing!

I recently received my Aune Mini USB/DAC headphone amp mk2 which I have hooked up a Dell Windows Vista laptop with USB.In addition I have a pair of Audioengine 2 amplified speakers and I am using Sony V6 headphones. Windows recognizes the Aune as a USB Audio DAC with a bit depth of 16 bit not 24 bit or higher. Is this the correct setup or designation? Thanks.

Dear uzmininu,
Thanks for the quick reply and info. The audio output is extremely quiet with no background hiss. I am breaking it in now.This is a fun hobby to have!

I am using Vista with my new unmodded Aune through USB but I find I cannot adjust the volume in Windows control panel[the sliders have absolutely no effect on volume or muting] going to the Aune which is causing a clipping like distortion that is driving me crazy. The only control I have is in the software player I am using at the time be it Foobar2000, Winamp or Itunes but this does not help if the sound coming from the laptop through USB is too high. Please advise.Thanks very much.
N.B. I think I found problem Foobar2000 had replaygain enabled which caused the clipping.Once disabled no more distortion!

If you are using Foobar try downlading WASPI and/or Kernel Streaming plugins...
Both bypass windows sound managers and give bit perfect digital sigal via USB to your Aune or any other DAC/Player you might want to use...
Make sure you set Foobar output to WASAPI or KS output at 16bit, on USB (Aune) Audio DAC, and keep buffer low, at the far left.
Keep volume on Foobar at maximum and use control volume from Aune...
MERRY CHRISTMAS!!!!!!!!

What should I do about the installed Sigmatel driver in Vista while using the USB Aune? I disabled it in the Control Panel Sound applet then set USB Audio DAC as default. Is this correct? I do not have to uninstall the onboard Sigmatel audio driver from Vista ?

The on board sound driver has absolutey nothing to do with the Aune or Foobar...
If you have the Aune pluged in, it is recognized as another audio device (USB Audio device) and no additional driver is nececary.
To listen through your sound card (through your laptop speakers or laptop headphone out) you must have it set as default device in your playback devices and obviosly you need to have the correct driver installed (Sigmatel for DELL).
You should not set the Aune (usb audio dac) as the default device.
Foobar should be set like i told you above. Bypassing windows manager means that windows do not interfere with the digital signal at all and it is fed bit by bit (bit perfect) to your Aune external DAC.
If you have done all this and the problem persists then it certainly is not a problem of the Aune.

Everything is working fine with the Aune as default and the Sigmatel driver set as disabled in sound properties in Control Panel. If I want to use the laptop speakers I will reenable it again as you stated to use the onboard audio again for that purpose. Thanks for the help.
What do you think about the SOX resampler in Foobar2000?
I am using WASAPI for output with 16bit depth and dither in Foobar2000.

By the way, is it possible to add the quartz clock source to the DIR9001 chip? Can it help to reduce the jitter level via the S/P DIF?

Can it help to reduce the jitter level via the S/P DIF? alexrozen It would depend on how they have configured the DIR9001 (see DIR9001 data sheet) A worthwhile improvement can usually be made by replacing the "flywheel" time constant capacitors (pins 22 and 23) with close tolerance polypropylene types. (C1: Loop filter capacitor, 0.068 mF. C2: Loop filter capacitor, 0.0047 mF.) Alex

PinkFloyd, Is the Aune still the best amp for the money that one can buy today in your opinion? What about the DAC?

Hi, Apologies for posting to a very old thread, but not usre if justifiable to start a new one. I have had the Aune Mini USB DAC MK ii SE for quite some time now and lately i started getting a 'unknown USB device' error from win 7. I suspect some kind of USB communication error which can be a result of many different things but have no way to diagnose.
Anyone seen this? tried checking voltages and resoldering some joints that looked suspect, when out of the BOX the DAC intermitently gets recognised, but there is no recognisable pattern behind .
I am almost thinking of just ordering the PCB with Parts from HIFIDIY because I really like it very much especially with Lm 4562HA in both positions. So have no reservation of cranking up a soldering Iron if that is what is needed
All help welcome
Thank you all

I don't know the answer, but I frequently get this with USB devices from both W7 and W8. I dismiss the message, and normally the device then comes up O.K. If you get enough errors like that, W8.1 (at least) marks the USB port as faulty and disables it. In fact, it disabled both my front USB ports , making it look like a hardware problem. The cure appeared to be to use System Restore to go back before the port was disabled, and then they both worked normally again.

I also get more hastle from W8.1 than others OSs on the USB side of things. I have an USB HDD (PnP) that just cannot fire up on W8.1, while all other USB HDDs in my possesion have no such problem and all of them work fine on W7. I've tried everything but no joy, I'm following a thread on the Microsoft forums of someone with exactly the same problem with no solution as yet.

Having another go at this I just found a solution to my problem. A power injector! Works perfectly

I've got the best solution............ Windows XP. Up until recently I would have agrred with you. However, I've found 7 to be a huge improvement on XP, still familiar, far more logical and much slicker. 8.1 takes some getting to know, a few freindly tweaks and some patience and it really isn't as awful as peeps say. I even find going back to 7 a little "quaint" at times!
