I have the Aune T1 and the Bravo V2 (unmodified) which I drive with a Stoner Acoustics UD110 DAC. Hard to say which one I like best, if pressed I would pick the T1. total cost of both is within $10. The T1 is a trimmer package, the separate UD110 DAC and Bravo V2 amp are a bit more versatile. I have Amperex Orange Globe  tubes for both (they use different tubes), I would say they are my preferred tube so far.
 
They both sound awesome to my mostly untutored ears. I usually listen with my Beyer DT770.


Dana....give these a try
 
For the AUNE - GE 6DJ8 USA or SEIMENS 6AQ8

thanks for the advice, I'll keep looking for those for my Bravo. For the T1, I bought a nice stash from mhamel and have picked up a few more since.
 
I am enjoying this immensely.
 
I'm not sure about your taste in music, but for test tracks I highly recommend the Steve Hoffman 1985 remaster of Who's Next. You can get it from ebay Canada. I listened to that with my T1/Amperex OG/DT770 the other night, wow. It showed me how critical the remastering is. Tube-rolling and remaster-rolling. This hobby can be fun.

dana789, what Amperex OG did you get from mhamel exactly? 69` 6DJ8 single support leg dimpled disc GAC coded? He had few of those for selling. Still one of my best tubes for rock/metal/progressive/jazz and they are really appreciated in Lyr thread also.

He sold me a 1969 Amperex OG 6DJ8, from Phillips/Amperex Herleen, Holland, Sept 1969 from the etch date. I'll check the other details tonight.

What would be a good cheap tube amp ($130) to go with the Aune T1 Tube DAC? I'm primarily looking into the Little Dot I+ for the tube rolling feature and better build quality compared to the Bravo Tube Amp.

I primarily have low impedance headphones under 70ohms and don't plan on getting anything over that. I have/plan to get: Q701, Pro DJ100, Momentums, SR225i, HE400. 


So yeah or nay for the little dot I+ with the aune t1? Only going to be using them with low impedance headphones 70ohm or lower and the I+ drives low impedance headphones great like the grados which I listen to the most.

1969 Amperex 6DJ8 / GAC, dimple disc getter, single post support... Herleen, 4th week of September, 1969 mfg.
 
Section matched < 2.3% difference in Gm, < 1% difference in Mu (Gain).
 
 
I have 2-3 matched pairs left of the GAC coded 1969s, I don't think I have any singles left, I'd have to check.

and it sounds great! As Mike advised, this was a very good starting point for me. It was reasonably priced and made the merits of a good tube obvious to someone new to tube rolling.

  ^^^ two tubes out of this are questionable 
Sylvania 6AQ8 ECC85 Black Plates and RCA 6AQ8 Gray Plates have some base/bass distortion (looks like copper rods are on fire)


That sucks..and those are two good sounding tubes...defective ?
 
I received my black plate today..DEFECTIVE..uggg...Right channel about 1/2 of the left..never had that happen...sucks
