Ultrasone Signature pro .. and Hifiman he-400  and both pair well with this T1 but the Ultrasone is the best.

Can you make more analytical comparing with some other tubes? Just saying "smokes every other tube" won`t say much. Ppl taste is different and would be good if you gave more detailed impressions.

 

Can`t say much about different cans but with HD-681 mkII, Aune T1 makes perfect match imho. All I know is AKG K540 sucks big with it (it`s sheisse can anyway).

You know, I'm not aware if everyone is knowledgable with this tweak/setting to do when running the USB DAC, but for Mac's when you reach into the settings of "Audio MIDI Setup" the output settings should reflect like the picture below to prevent the signal from being scaled by OSX. After making that small change, it's made a giant difference for me where the sound is a whole heap cleaner.

 

 

 

On another note, is it safe to plug the tube in after having turned the DAC unit on? I'm not sure, but the past few days I've been experiencing again the issue of the usb dac not working with the mac again, but just now I decided to unplug the tube and turn the unit on. Immediately that got the dac recognized in the sound preferences, but I can't be 100% certain this is the method to go on, as previously I had a back up drive plugged into a the USB at the back and it was a suspicion of mine that the drive was hogging the USB power so the bus wasn't reading the dac. When/if the usb dac decides to not work again, I'll be sure to plug in the back up drive and then test my theory out again. Until then, I get to enjoy music again with the T1 and I've learned a little thing about the audio setup aspect :)

A typical rule of thumb for tube equipment is don't remove or insert tubes when the equipment is powered up (and sometimes even plugged in). A little more obvious with integrateds or power amps, but still a good rule to live by for other types of tube eqiupment. Less stress on the tube - not sure what it may do to the rest of the circuit.

you know that's what I was afraid of, so the next time the DAC takes a dump on me and decides not to work again, I'll just have to see if A) powering the tube is drawing too much power from the USB or B) my backup drive being plugged in at the same time as the DAC is hogging the power to the serial bus, which is what is causing the DAC to not be recognized by the system...thanks for the confirmation :)

Ok managed to find one for £11 + £3.5 shipping. Thanks for the tip.

I usually always turn off T1 and then roll the tube but I tried and you can also do "hot swap". Nothing bad happened (just signal got lost) and you have to wait for tube to warm up hearing "crackly" sound in the beginning. Still I don`t recommend to do it.

 

Salvatore, if I only had experience with Aune T1 @ mac I would have told you it before. On Windows it`s same thing with using KSP, WASAPI or ASIO. It made huge difference after using one of them to avoid windows internal processing. I use ASIO4ALL + ASIO winamp plugin. KSP is easier but it may have problems with 192/24-bit playback.

 

Also, little OT but Aune T1 + Thom Yorke new album gives absolute eargasm: http://xlrecordings.com/buy/atomsforpeace/amok/

I read the first post and pulled the trigger. Bought one from some UK-ebay seller.

joeq70 seems to be very confident about this DAC/amp.

 

Is there somewhere a FAQ about how to roll Tubes?

post #999 of 5565

Is the ecc84 compatible with the t1?

And I found this one: 

NOS NIB GE 6BQ7A 6BZ7 VACUUM TUBE =6DJ8 + 10% more gain, & replaces 6AQ8

what do you think?

Google is your friend - lots of info out there regarding the care and feeding of tube audio equipment. I found some good info on the FAQ here, about halfway down, but there is lots more info out there.

 

Edit: Actually not as much info in that one as I initially thought. Here is a page with a nice summary of the basic issues.

BTW, it is a good idea to NOT touch tubes with your bare fingers, even if cool. You hands deposit all sorts of grease and oils onto glass surfaces which are not good for tubes when they start to heat up. There are some inexpensive tools for handling tubes, but a nice lint free cloth always works well.

Thank you for the links.

This is MYTH! Read lot of articles and opinions about it. They don`t get even so hot to "burn in" deposits on the glass. I remember one old radio-guru laughing about this nonsense... he was swapping and testing tubes for 40 years and some tubes were sticky as hell over the time - made absolutely NO difference in ANY way. Maybe only things to consider taking them with "butter" fingers - deposits may dissolve markings on the tube and its just harder to pull them out due slippy surface on the glass. Also maybe aesthetic looks of light-up tube. Other than that - NONSENSE! Can say it also from my little experience with tubes.  Myth!

As far as I know - they do not fit. There is list of tubes that fit earlier somewhere in this thread. But maybe I have overlooked on these.

Coil is right

Yea I checked with that list and these weren't on there but i tought, maybe there are some more types that fit. ;)
