Aune T1 USB Tube DAC+Amp Discussion Thread ***See first post for FAQ*** - Page 58

Thanks for the links. Glad you like those 700s.

Hey T can you on me your price on the anniversaries? Thank you

 

My brief impressions @ rockgrotto:

Edited by CoiL - 2/19/13 at 1:31am

 

Thank you for this. It sounds like the 6N23p is a very good tube to compliment my fidelio x1. The 6922EH would make the X1 too much, waaay to much. It already sounds like how you describe that tube. I think i'd get the standard version and get a tube off ebay somewhere. 

This is where I will buy the standard version: http://www.smalltao.com/product/17094328358/The%20AUNE%20Standard%20T1%2024BIT%20TUBE%20the%20DAC%20tubes%20fever%20-%20sound%20card%20-%20decoder%20-%20tube%20amp%20-%20amp

It's 115 euro's shipped, seems like a nice price!

 

I'm not interested in toschek's amp since it's the silver version. Not really my taste :)

 

I'm a bit of a nub and can't seem to find the tube you mention here. I don't know what the rocket logo should look like anyway and in what price class I should look.

Could you have a look for me? http://www.ebay.nl/sch/i.html?LH_PrefLoc=2&_nkw=6N23p&_sc=1&_sop=15

Yeah, but what about custom taxes in NL? It comes from Suzhou (Jiangsu).

 

I ordered mine from UK and paid 169€ for upgrade version (free post) but didn`t have to mess with custom tax ;) Fast door to door shipping also.

This is the UK eBay seller i got it from: http://www.ebay.co.uk/itm/AUNE-T1-24bit-96kHz-Tube-Amplifier-USB-DAC-6922-Upgraded-Headphone-Amp-/251164443176?pt=UK_AudioTVElectronics_HomeAudioHiFi_Amplifiers&hash=item3a7a914228&_uhb=1

I got 2x rockets for $8 (+ $10 for shipping). The seller I got them from is, however, out of rockets atm (http://myworld.ebay.com/polivoks-shop?_trksid=p2047675.l2559). The tube looks like this (has rocket logo with text 6H23P):

 

 

 

 

 

This seems pretty similar: http://www.ebay.nl/itm/2x-6N23P-E88CC-6DJ8-Tubes-NOS-198x-VOSKHOD-/321070434800?pt=Vintage_Electronics_R2&hash=item4ac14a09f0

 

If you aren't in a hurry you could try lurking in ebay and wait for the best deals. I have to empasize that, even though rocket sounds very nice, its an entry level tube. If you want to go straight for the high level and more expensive tubes you should ask advice from somebody like toschek or coil who has been doing more rolling. I don't know how rocket will go with X1, but with K702 65th anniversary it goes nicely. Rocket has warm intimate signature, but the soundstage is not the widest and the bass is not the best I've heard. It's not perfect tube but for $10 a must buy and good starting point for every roller. If you are interested for the 6922EH I can sell you mine for affordable price :D

 

E: I have to second Coil. You should avoid taxes. I bought my T1 from that same seller (kidult510). Nice seller and very fast delivery.

Hmm okay, I'll look around, so far I never got troubles with customs when ordering from China.

But if they do tax me they probably add 40 euro plus handling fee.

Thank you guys for your help!

Did more comparing with 6922EH and what I can say is that Mazda PCC189 has definitely better bass - tighter, more depth, more kick, more controlled and goes very deep. Highs are more sparkly, accurate and more in focus . Vertical soundstage feels same. Now, the bad part of this tube is tiny lack of mids. Acoustic guitar and female vocals suffer from it. Because of that I think Mullard ECC88 is littlebit better for rock/metal/jazz. But because of Mazda PCC189 larger soundstage and better bass - it`s better allarounder with different genres. With some alternative rock I still prefer Mazda PCC189 to Mullard ECC88.

Anyone willing to try these? -> http://www.ebay.co.uk/itm/120939077278?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649

Should be russian made and look like 6N23P.

I've been browsing through Lyr tube rolling thread as toschek suggested and stumbled across this link: http://www.audioasylum.com/scripts/d.pl?audio/faq/joes-tubes.html#6DJ8

 

old post but seems like a good read for all of us T1 rollers.

Forgive the complete ignorance, but given so many manufacturing countries for these valves/tubes how come I've not heard of anything coming out of Japan? Or is it just something not worth mentioning? 

Yeah, I know what you mean. I also searched for some Japan/China made tubes and found these:

Matsus h i t a, Raytheon, National are the keywords for Japan tubes. Some Mazda labeled tubes might also be Japan made.

We kinda destroyed the Japanese tube industry and by the time they were recovered they focused on the transistor

Hey guys I just figured out something,
I was experiencing some hum or noise when nothing playing, but it wasn't all the time, so I swapped my tubes to be sure it isn't their fault, and actually, it isn't !
No matter wich tubes I ve put in, the noise was still there, so it must have been my environment, or the amp section.
I tried several things such such as turning off all the electrical devices near to it, and it happens that my aune is sitting very close to my old 20 LCD screen, which was on all day long. It isn't a led one so it draws some current lol, and emits quite a bit of electromagnetic field, so I just discharged it by touching it bare hands and miracle all the hum/noise is gone :-)
All my tubes are dead silent now, so just to say,these little valves are sensitive to such things, that we could easily forget...
BTW just loving my rtc e188cc, even if it is used, it is a really great tube, listening to apocalyptica right now, and it feels like I m just in the middle rocking with them :-)

Hmmm... got to test this with my Mazda PCC189 (only tube that has audible tiny hum when nothing isn`t playing and knob is at max), my Aune T1 sits just under LCD.

BTW, folks, how to I remove the acrilic protection without breaking it?  I'm about to receive the first tube to roll. :-)
