I am really interested in the amp, but am unsure as to how I would hook it up to my tt. Could I use it as a pre amp, ie have the output going to my pioneer reciever and then listen through that?

I wondered the same thing. I'm pretty sure the point of the T1 is that it's a DAC that uses a tube.

 

Since the TT is analog, the T1 wont do you much good as a digital audio converter. You'll need a pre-amp that uses a tube for a TT.

 

I think you could route the TT through a laptop - but then...what is the point. blink.gif

 

 

...I'm actually probably ordering a TT and pre-amp today. I'm going with the Cambridge Audio Azur 551P for a pre-amp.

About cleaning pins that have oxidation due time (NOS tubes), use 30% vinegar (not apple vinegar) + baking soda and leave it for about 30min. Clean under running water. If pins have some kind of sticky stuff, I would use Nitra-A solvent. The thing I would certainly not do is use sandpaper or some scraping method.

 

e: I`m waiting for my Philips PCC189/7ES8 (Heerlen Holland) and Mazda (Mullard) PCC189. Got them very cheap. There are 2 more tubes I would like to get but maybe next month. Damn that money-sucking-little-black-box! -.-

 

e2: I think I have to buy socket saver like this: http://www.ebay.com/itm/8pc-9pin-Gold-Vintage-Tube-Socket-Saver-6DJ8-12AX7-ECC83-12AU7-ECC82-6922-AMP-/140892378813?pt=Vintage_Electronics_R2&hash=item20cdd716bd

Also, it would "kill" the LED under tube for those who don`t like it glowing.

 

So, would this allow me to use a 12AX7 with the Aune T1?  I have a couple of 12AX7 laying around, but I thought they were not compatible with the T1.

Would it be possible to desolder/cut off the led without damadging the aune itself? Or should I put some black tape over it?

NO! It`s only a socket saver! 12AX7 and 6922/6DJ8 etc. share the same noval 9-pin socket but pin layout should be different!

If you redirect pins physically somehow (mod the socket saver), then it might be possible but some specifications may differ too much (not sure). 12AX7 specifications (type 12ax7 in search box): http://www.mif.pg.gda.pl/homepages/frank/vs.html

 

Also, got 2 of my PCC189 tubes. I don`t know if Mullard PCC189 was already damaged or it got damaged when I dropped it on the glass table, it has crackly leaky weak sound -.- It`s propably leaking because when I turn T1 on, the bottom tube grid goes on high glow fast for about 3sec and then the rest of grid starts to warm up - it`s not normal. 

 

Anyway, the other one is with Mazda logo, made in England, BVA, B(might be 8)9i5 code. This tube: http://www.r-type.org/exhib/aaa0882.htm Don`t have time atm to compare but briefly - very pleasant soundstage and compared to my amperex it`s pulled back towards me so there`s more room and air in the back my head. Vocals are very clear, smooth and intimate. Like this tube very much but can`t tell atm if it`s better than amperex or not. Seems that tube is better for rock/metal/jazz but sounds very well with electronic atmospheric music (better than amperex). It might get the 1st place for my overall different music genres performer but have to dig more into it. Also one little note, since it has thin glass it has very tiny hum when music isn`t played and vol knob is turned to the max. On normal listening levels it`s inaudible. 

Will make more detailed comparsion when I get my Philips and Lorenz PCC189`s.

I will be getting the T1 soon. Is it worth it to go for the upgrade tube version for an added 20 euro? It's the:

Electro Harmonix出产的EH 6922

 

Or should I buy the standard version and buy a tube myself?

post #848 of 6431

Where are you going to buy from? Most resellers already ship them with upgrade 6922EH tube. What`s the price with stock tube 6n11?

Maybe we can recommend some better place to order from? Give us link of your purchase place.

 

For 20€ I personally would not buy it. Instead I would take stock version and buy Tungsram PCC88 tube from ebay (they are cheap, with same soundstage and littlebit more tight/punchy bass at lower volumes).

FYI, I haven't had much time to spend yet with this combo, but first impressions are that the T1 is a very good pairing with the HD 700s if you're on a budget as far as amplification is concerned. I am sure there are better pairings (Lyr, Valhalla, DNA, WA6) but the T1 gets the job done.

More to come as time permits.
post #850 of 6431
BTW, I will be listing my T1 on Wednesday most likely. I'll be including some single tubes since I can't use them in my new amp - 1x each of 6922EH, 6N23P and 6N23P-EB. Just a heads up to anyone considering pulling the trigger on one of these in the next few days.

Thanks for the clarification, CoiL.

Some people like 6922EH and I consider it a nice backup tube, but my suggestion is to go for something better. If you don't have too much experience with tubes then it's kind of hard to know what to get. EH is wide and clear sounding tube, but for my taste the imaging is not the best. Somehow I don't find the vocals to fit nicely in the mix. Therefore I would only use it for electronic and ambient music. The sound stage is kind of bumerang shaped... goes very wide but doesn't feel as balanced forward wise. There are lots of people, however, who think otherwise and consider this as a great tube. 6N23p rocket is more intimate, lusher and has more bass, but the soundstage is somewhat cramped. I find rocket to go especially well with gritty blues and blues rock. You get this sweet house of blues kind of presentation. Imaging is good and you get nice instrumental balance and separation, but like I said the sound stage is more narrow and forward centered. The rocket is not for everybody and therefore I can't unconditionally recommend it for being used as the main tube. You should get it just because of the cheap price and good bang-for-the-buck value. I have ordered Genalex gold lion and Mullard shield logo and will post more impressions/comparisons after I get those tubes. You need to start the tube rolling from somewhere and after that it's kind of hit and miss until you find the best tube for your system and your tastes. I know I'm still looking for the right tube. I wouldn't mind finding a tube that has rocket logo signature with extended soundstage.

 

Maybe you should buy that T1 of toschek's. You get nice starter collection of tubes on top of the amp. I bet the price is also good.

 

Any new purchases or comparisons.... anyone?

So is it possible to briefly compare your 65s against 700s in T1? Or did you already let the 65s go?

post #854 of 6431

Just listed my T1 in the amp section, I'm not sure what the rules governing flogging ones own classifieds in regular threads are, but I'm offering a good deal w/ extra tubes thrown in.   PM if interested or have questions, you know where to look.

 

Cheers :)

I compared them in the 700 appreciation thread, here you go:

700s are definitely a keeper IMO, and they pair really nicely with the T1.
