Aune T1 USB Tube DAC+Amp Discussion Thread ***See first post for FAQ*** - Page 404

I need a good tube for my HE400, something that can tame the highs and less aggressive, and probably bigger soundstage too, any recommendations?

V

HE400 already has a Panorama Soundstage. Still not wide enough? How many hours your HE400 already break-in?
I believe you can buy different Tubes to tame it out.

Oddly enough my T1 is still smelling like hell, even after staying in the basement for like one month or so. If anyone wants a smelly T1, give me a shout.

Just purchased the Aune T1 from Amazon for $220 and added on the $40 Genalex E88CC tube which I'll swap out. I'll keep the tube that comes with it around as a spare. Will report back my thoughts with my HiFiMAN HE-500s in the coming days. The DAC should arrive tomorrow.

Cool! I would recommend trying the Focus pads with the HE-500's as well... or Jergpads as they used to be called. I would really love my HE-500's if they weren't so damn heavy. Still can't adjust to them so sticking with my HD-650s mostly. I do put on the HE-500's every once in a while and feel like I can hear maybe a touch more highs, and deeper/wider soundstage also by a bit. Tough to say without getting completely adjusted to them, but my neck gets sore lol. 

 

Let us know how you find the T1 with them.

My Aune T1 makes a crackling noise if left to idle for more than a minute. So basically if I pump music through it as soon as the light comes on and never pause, the sound quality is fine. But if I leave it on for a few mins before starting the music or pause for a few minutes then start it again, there is a crackle/static almost as loud as the music. Short (<1min) pauses don't trigger the issue. The static crackle isn't constant, its like its a part of the music and gets louder and softer as the music gets louder and softer. Once the crackle has developed, I need to switch the unit off for a minute or so to clear it. If I flick it off and on again too quickly, the crackle is still there, but not as loud.

 

I tried many different tubes, issue stays the same. Does what I described sound like the kind of thing a capacitor might be responsible for? I don't have any return avenue since it was fine for the first month or so before developing this issue. Keen to fix it if I can...

 

After a lot of superstitious speculation, I believe I may have found the actual cause of this issue and can now replicate it at will. I don't expect anyone to believe me but on the offchance it helps someone else with the same peculiar circumstances, here it is: when my stumpy little logitech wireless mouse receiver is plugged directly into the machine (doesn't matter which port), I get the weird crackly static after pausing and even some random dropouts during long listening sessions. I moved the little receiver thingy to a usb port on my keyboard and boom - no more issues. Now I can get back to working out tiny differences in ancient vaccuum tubes instead of spending my days paranoid about crackles...

 

Before I moved the little wireless dongle thingy away from the machine, I was able to get rid of the crackle just by unplugging the usb and replugging it - no reboot of the aune needed. So this is definitely a USB interference issue and nothing to do with the aune t1.

Finally got my hands on an Amperex 7308 and it's definitely worth the price tag. Switched out all the caps too since mine came with 4 generics and 4 elnas.

 

Anyone know where I can get 6N1Ps cheap from the US though? Or want to sell/trade one? I've have 6 now and none of them work. Was starting to think it was my T1 but I bought a second one because I wanted to switch to black and they still don't work.

I am so anxious to get this and see how it sounds. This is my first amp!
