Agree with the Mullard part, it`s great tube, but don`t agree with the EH being flat and dull part. Maybe it`s from your headphones (flat sounding cans?) that can`t represent such spacious soundstage? 

 
You may be right, I have compared them with the HD650s on V200 and Aune T1 as DAC. I may compare them with the Beyer T1s which have better soundstage. Also I should mention I didn't really test or comment on the soundstaging abilities in particular, I meant flat as in less dynamic than otherwise.
 
Later edit:
I was listening to rock/metal earlier with my HD650s, and that's where the EH wasn't doing anything for me. 
 
Beyer T1 + EH + electronic music: Appreciate the soundstage, not so bothered about the negatives compared to Mullard
HD650s + Mullard + rock/metal: No contest here
 
I hope this is a more fair assessment and thanks for the suggestions.

Has anyone tried the HD 700s with the T1? Considering a headphone upgraydd. I love the Annies but I heard the 700s today and they really opened my eyes, just wondering how they'd perform. Doesn't seem like they'd deliver the max input power (400mW) at 150 ohm if what I've read of the Aune's ohm/watt relationship on the internet, and we all know everything on the internet is true.

ohhhhh, that sounds like something I would be interested in too. I like the 702 and 650s but those 700s look spectacular. MAybe I can get a hold of one soon

 Also this seller seems legit: http://www.ebay.com/itm/2x-6N23P-E88CC-6DJ8-TUBES-NOS-NEW-USSR-MILITARY-FOR-AUDIO-AMP-PREAMP-VINTAGE-/170978975997?pt=Vintage_Electronics_R2&hash=item27cf2420fd $8 + $10 is not bad for 2 perfectly working rocket logo tubes.

Might grab a pair from that seller while I wait for my Amperex 7308.

OK, These look like what I misidentified as Shuguang

This JAN Phillips is prolly worth a get too

If I were most guys here I would pick up those two and the rocket to really give a go before dropping some real money on the various amperex, mullard and teles. Seriously, Im having more luck right now with those than some really expensive Amperex

Well, I cleaned the contacts on the 6922EH

 
What's the best way to clean those pins?

 

[Salvatore]

sorry double...
 
Edit: @toschek Dude! Not a bad idea to go for the high end senns, but please PLEASE consider of going straight for the HD800s. You can get used for decent price and they should be far superior as compared to 700s. I think 700s are overpriced and you should at least try the 800s first.

Plugged in my Aune T1 and HD650's today and using the tube that came with it (electro harmonix 6922EH) getting some hiss when I increase volume like 70%+ is this tube related? only using the 6922EH until my other tubes arrive got no other option atm. 

 

[dcfis]

Tube is microphonic or your pc or unit gain is too high. Thinking about it, prolly not pc related

Another bad-going EH tube? ;S My EH is dead quiet.
 
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.

I really like EH with certain songs / music styles, but the more I do A/Bing between EH and rocket the more I think there is something slightly off with the EH.

Nice idea. Especially for you major rollers. I might consider this myself if I end up getting lots of tubes.

Ok guys, I've just received the Aune T1 + 2 Tubes (Electro Harmonix 6922EH & Genalex Gold Lion E88CC/6922). I'm breaking in with a Sennheiser HD598. Totally satisfied with my purchase!!!  Will come back in a few days with my impressions of Electro Harmonix Vs Genalex.

 

[dcfis]

I don't think anyone will ever wear out that socket is a high quality ceramic. You can also pull the tube when is powered on to roll tubes without losing sync. Just turn the volume all the way down and let the new tube power up for thirty or so seconds before turning out up

Lookin' forward to it. Was considering the Genalex as well.

Ceramic isn`t the part(s) that wear out and high quality doesn`t prevent wearing. Metal to metal friction will wear both pins and socket, it`s a fact. Better pay that tiny sum for socket saver than start to take apart T1 and change socket.
