Unfortunately if you block the LED the tube glow is pretty small (I gather because the tube is only being used as a buffer). CoiL did some posts about using red plastic, which gives a nice tube-like glow. Note that even the Woo WA7 uses (red) LEDs to enhance the look of its tubes.

Guys, any idea of how this pairs with the he-500?

google this: "aune t1 he-500 head-fi" there are plenty of earlier entries in this thread. I realize this thread has gotten huge, but it seems Google knows all about it.

 

For general searching in head-fi, I find google works better than the head-fi search functions if I simply include head-fi in the search. YMMV. The  search options in head-fi work pretty well too. I just tried "search this thread" at the top of this page for the he-500. It works great.

I set Foobar for Wasapi event mode with a 200ms buffer or so, and it never has any issues playing off my laptop or desktop drive. Externals will occasionally pause during playback for a few seconds because Windowsneeds to read the directory or something silly like that. This only happens when I have left it idle for a while and I assume it could be solved via power settings. Haven't looked into it yet.

I think most USB issues are not actually jitter, just related to buffering.

Just some ideas and places to investigate. Hope you can eliminate the issues smily_headphones1.gif

 

Thanks for the follow up, mikoss.  I did manage to eliminate the issues.  No need to upgrate to V2... at least to me. :-)

 

So, I am running Wasspi with 3200 ms of buffer, event mode, no external drive, a single device in USB (Aune itself), HD is a spinner. 

 

More importantly, I think, I gave Properties >> Advances >> Playback >> WASAPI:

  - push mode: 500 ms

  - event mode: 100 ms

  - high worker process priority: on

 

(Note the increase of 5X in event.)

 

So, I think you are right.  Buffers appears to be the issue.  But I take there is the overall buffer and the specific one for the Wasapi type (Properties >> Advances >> Playback >> WASAPI)??

Mine will be here Wednesday.  Can't wait to try it with my HE400s

I've had a couple of weeks with the T1 and 7308 tube and must say the combo with the BH2 (from the T1 audio outs, bypassing the amp section) to the MDR-7520 is really impressive. I love the synergy.

 

I do notice that the tube needs at least 30 minutes of play time before the sound is optimal. The coffee kicks in about the same time. :L3000:

I use this at home sometimes and love it, Make sure you experiment with tubes until you find your liking.

I would highly recommend Ultron tubes, they sound magnificient and takes the pairing to the next level.

post #5260 of 8012

I have decided to let go my Aune T1 with EH6922. I also have 5 other tubes namely Amperex 7308, 6DJ8, Tesla PCC88, Tungsram E88CC (the best sounding one for me), and supposedly Siemens ECC88 (no more markings). I'm based in Shanghai, China. So anyone interested, please PM me.

Thanks, ramaka.  Where do you pick these up?  I didn't find any on Ebay.

I'm wondering the same. By the end of the day, my set-up sounds so much nicer than when I turn it on in the morning. Would the main concern be the tube not lasting long, or something else? Can someone enlighten me on tube etiquette?  :smile:

post #5264 of 8012

Tubes has their own life times. Some have 20,000 hours, some 50k, some more, some less. So when you leave the tubes on, it would decrease the life time. But at the same time, tubes sound better when they're hot, and being hot reduces the life time.

It's really up to you. You can just get new tubes if your current ones burn out. I personally don't mind them burning out, wrap them in small cloths to keep the heat in, makes them sound really smooth and liquid ish

post #5265 of 8012

This guy says heat is fine for tubes - they die just as fast regardless of heat. So basically just having them on vs making them do something uses it up just as fast. He also says low heat is more of a problem (!?) and that you should definitely let a tube warm up before running current through it...

 

It's not specifically about the tubes the Aune T1 uses though, maybe it doesn't apply?
