ASIO (Audio Stream Input/Output) is another method of audio transport which is superior to WASAPI as it bypasses the Windows Kernel Mixer (and the distortion this adds). Just like WASAPI, to use ASIO the media player will normally require some kind of output plug in, but it is only possible to use ASIO in Class 2 USB Audio mode (which allows transmission of higher data rates) using a dedicated driver (such as the free Cambridge Audio USB 2.0 driver). [Aune T1 can only support up to 24/96kHz so maybe doesn't require Class 2 USB Audio mode. Note: Class 2 USB Audio mode is NOT USB2.0.] 

ASIO is preferable to all Kernel streaming audio transport methods (eg. WASAPI or DirectSound) as it delivers lower latency, better jitter and no mixing of audio streams.

Can anyone verify this?

+1 I've read ASIO will have less jitter than anything else, if implemented/supported properly. The problem that I read (and reason why I think a lot of people stick with WASAPI) is with the driver implementation with Windows, which ends up creating more jitter than exclusive mode WASAPI.

I just find ASIO more buggy than WASAPI. I've played around with both and don't notice any differences in sound. It's mostly just a hassle to get it working consistently.

The miniwatt dario ecc189 that coil had described is really nice.
post #5164 of 5628

Why you have to say that isendono lol. I won a damn auction for a miniwatt dario on ebay and then the guy tells me , he can't find it refunded my money. Won it for $21 too.

 

Yea I read constantly ASIO getting it to work right can be a major pain on some setups. And I always used WASAPI because of the high res audio flac I have before I even got the Aune so I just kept using it.

 

Also agree it will depend on headphones and speakers used in how a tube will sound in your setup. I also felt my HD 650's were more bass than I wanted, or at least more than I was used to, and the Aune brought it in line and really opened the highs to perfection and sweet sweet mid's when I used the orange globe.

I didn't mean all fiio products. I just said about x5. The same with smsl sd 793 or smsl sanskrit :)

Bass is more controlled, is better overall... And i'm asking if there is tube that can make better bass to aune?

 

Change gain is not good option because i have 250 ohm and 600 ohm headphones :) But i can try...

 

I'm still waiting for my aune t1 :) But this one which i have to test is very nice. Just the bass and soundstage could be better. With dt 880 it is not so bad, but with my stereo...

Start with FAQ and info post. Those will get you started.

I got my Aune T1 a few weeks ago, and I wasn't overwhelmed with the new sound, because the stock EH6922 tubes didn't sound too different to my Fiio E17. If anything I felt the E17 had a little more bass. But I don't have golden ears, so I probably can't pick up to many subtleties in sound, so take my words below with a grain of salt.

 

Then my 'new' Amperex Orange Globe ECC88 (Dimple getter A frame) and GE Mullard ECC85 Blackburn (Made in Great Britain) arrived this week. Now I'm happier.

 

The Mullard needed some burn in for the sound to settle, it was horribly distorted without having a couple of hours put on it. Now it's fine straight after it turns on. Sound wise It's smoother, and more well rounded than the E17/EH6922. Overall it's a good sound.

 

Now I'm listening to some Jimi Hendrix Vinyl 96KHz rips on the Amperex, and man it sounds like the man is playing and speaking right next to me. I suspect both the recording and the tube signature came together. It's great! The airiness of the sound really provides a nice stage for Jimi and his band and the funky tunes their instruments are making.

 

I'm happy with my purchases, and won't be doing any more tube rolling, I think I have the best amp/tube combo $AU 200 can get me :)

"I wasn't overwhelmed with the new sound, because the stock EH6922 tubes didn't sound too different"

Yea totally agree with both those statements. And I have orange globe o ring getter now and I at first impression feel I like the dimple disk getter better, but I have to listen bit more with new ring getter version to be sure. I honestly don't think it's worth it at all unless you tube roll. I didn't feel it sounds better than my built in ASRock Purity Sound built into my motherboard, although granted that's supposed to be a high end sound chip and amp capable of running 600ohm headphones. But still I totally could live with nothing but a entire crate of Orange Globe tubes and be happy with only it.

 

I'll keep searching ebay and trying to find steals on other tubes though just cause. I have 2 dimple disk and 3 o ring now, bugle boy and stock tubes. Where to go to next...

Radiotechnique.... I haven't Orange Globes but I have a Buggle boys. Radiotechnique may be a good option for you. Good luck!

Does anyone knows whether Aune T1 USB is asynchronous or synchronous mode? What's the differences between sync and async mode?

On page 204, do a little light reading next time :)

Just did some brief comparisons of my Amperex 7308 White Label JAN, Voskhod 1978 Rocket Logo, and Russian 6H23N-EB on my new HE-560. The Amperex is definitely my favourite tube overall--best soundstage, clear extended highs, smooth mids and deep, impactful bass. The Rocket Logo had more bass impact and forward mids, but sacrificed too much soundstage for my liking. The 6H23N-EB was my least favorite tube out of these three as it sounded somewhat flat and only beat out the other two tubes in bass extension.

 

I'm tempted to try the Orange Globe with all this hype about it. However, the comment that SpiderNhan made about it lacking some bass concerns me, since I like having enough bass impact for some electronic music I listen to. Anyone have experience with both the Amperex 7308 and the Orange Globes?

Nice impressions; I felt the same way about the Russian tubes compared with the Amperex tubes I've heard. The Amperex 7308 PQ Holland date code delta 3E2 I'm rolling right now definitely has enough bass for my liking.

 

The orange globe I tried out was NOS from the '70s, a-frame, dimpled getter and date code delta 0J4. I also found the bass to be lacking compared with other tubes. CoiL recommended trying out some OG's with dimpled getters, so I bought these:

 

http://www.ebay.ca/itm/171308607029?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

 

Waiting on them and I'll let you know how the bass compares with the other OG's and the 7308's I've tried. I presume with those readings they may not be 100% NOS, but we shall see.

post #5175 of 5628

Anyone willing to explain to me how tube readings compare with each other... I have tried googling around and cannot for the life of me understand the differences between readings.

 

Here is what I'm wondering:

 

Hickok 800-A testers show their results in Gm

eg. 5500/5500

 

Jackson 648s, TV-7, B&K 707 testers show their results in I think percentage?

eg. 116/116

 

Tubeworld lists their tests in Gm, which compares with the Hickok 800-A results, but then it also lists some tubes with ma

eg. 20/20.3ma

 

 

My question is, how do you equate Gm to percentage to ma.

 

Also, as I understand...

Gm = mutual conductance = 1/ohms = "mho's" (aka "seimens")

percentage = tester reads the Gm and converts it into a percent, based on nominal rating from tube specs

ma = milliamps? This one I don't understand... the correct abbreviation would be mA, not ma. Also, how do you convert "ma" to mho's, or Gm.

 

Thanks guys.
