Cool. My Aune is connected to a Mac mini, but I do have 2 PCs.

Is there a fix to Bresh's question at the bottom of that blog entry? I remember once having a "USB not recognized", and a fresh OS install fixed it.
I was upgrading to W8 anyway, but is there a simpler less drastic solution?

If it's a laptop, try shutting down, pull battery, and reboot. That tends to fix a lot of usb problems. For a desktop, instead of pulling battery, unplug it and press the power button a few times to discharge the power supply. If that doesn't fix it, try checking the Device Manager and see if the device pops up with a yellow exclamation mark, that's usually a sign of bad/corrupt drivers. Updating or uninstalling/reinstalling drivers should do the trick. Fresh OS install is the extreme version of reinstalling drivers.

Nice. I would have tried all those except discharging the power supply. I never knew about that one (desktop).
Thanks!
 
I also learned about "Eject for Windows" on OSX from the X5 thread, love this site
 
btw, those in EST, WWDC in 1/2h.

there's a FS for aune t1 but it's 110V, while i live in 220V city... ughhh decision decision >___<
 
i can't find it locally, darn~...

Listening to my newly arrived Amperex Ecc88 Bugle Boy logo right now. 
 
WOW.

Last night I bought a US made NOS GE 6DJ8 for $22+ship (seller only had one, otherwise I would post).
 
I was intrigued by arcorob's impression that it is supposed to be like the GE German 6AQ8 but with a tiny bit more bass and slight less soundstage, considering soundstage and detail are already 5* in the German made.
 
I would also like to thank rwpritchett for his help.
 
Cheers

Whelp, the Mullard ECC85 I ordered off ebay has the same issue as my GE ECC85, with really annoying distortion on mid-low frequencies, and they both get really hot, like barely able to touch the tube hot, both of my other tubes don't get that hot.
Interesting thing though, is that the GE only has distortion on the right.
 
I tried cleaning the pins using a H202 and white vinegar, they seem to be a little cleaner now but it didn't really seem to help.
 
From what I can hear besides the distortion, the mullard sounds great.

try lowering the audio output level at bottom right of window from 100% to around 50% , and turn up the volume knob.

I would be trying different gain settings unless those are high ohm headphones.

hi guys.. i just checked aune website.. and they have the aune t1 mark II, which offers 24 / 192 playback and nonsynchronous clock technology...
 
what does nonsynchronous clock technology do and how will it affect sound...? i finally... found a distributor from neighboring country, but they only hv aune t1 in black (i want silver ) and aune t1 mark II in silver and black in a week and $30 more than the normal aune t1.
 
so.. here i am posting and asking...
 
cheers

I'm using 250ohm DT990s and I don't get that distortion with my 2 other tubes. The GE ECC85 only developed this distortion in the last couple of months, whereas before it was working perfectly, while the Mallard ECC85 has had distortion out of the box.
Once again for reference I'm currently using a 6N23P Vokshod rocket logo mostly(since the distortion is pretty unbearable in comparison), sometimes rolling to the EH tube that came with my T1.

Something to note is that lowering the volume output on my laptop and raising the volume on the T1 seems to help but only slightly on the GE tube, whereas on the Mallard it does nothing.
 
Could it be possible that one of my caps went bad since the ECC85, as far as I know, requires a higher power draw?

It sounds like you are getting pre-amp distortion before it hits the Aune T1, or the Aune T1 can't handle a signal as hot as your using.  If it is plugged in USB though, none of this makes any sense.  Do you know the difference between the distortion of a tube vs. solid state?  Now yes, the tube is the EQ, but it should put off a much different sound if it is distorting by itself vs. the SS amp board in the Aune T1.

Thing is, if I use the Vokshod rocket logo tube or the EH tube that came with my T1, I get no distortion even with both the T1 and my laptop at 100% with all gain dips set high.
I feel like the issue isn't that the signal being is overloaded as this isn't an issue across all tubes, and the Line In signal is clean too, so far this issue is localized to 2 of my 4 tubes.

some ecc85/pcc85 doesn't work well with aune apparently

According to Coil and his post it should work.

Tubes marked in green are tube types that I personally (and some other users) have tried with Aune T1 and seem to work with no problems.
Tubes marked in blue are tube types that other users have tried with Aune T1 and seem to work with no problems (not tested by me).
Tubes marked in orange are tube types that have been tested by some users but some of them did not work, probably due to "too high" mA current
draw or may sound distorted due to underpowered 9V heater.
Tubes marked in red are tube types that require custom socket adapter to work. * means that it has too high gain and
volume output level should be reduced from PC control panel.
Tubes marked in pink are tube types that do not require socket adapter but these tubes use higher current draw and might not be safe to Aune T1 internal components but according to user lwrs10 can be used safely. I`m not responsible for damage that may occur. Use with your own responsibility!

welp
 
now my second unit start to make problems
in the past week when switching song\moving on seekbar i got random "Thick" noises, and yesterday i had full white noise from moving the volume knob.
 
is that the tube?
