Could anyone suggest me a compatible tube suitable for the DT880 Pro?
 
I'm looking for a forward midrange, and a larger soundstage presentation.  The Amperex 7308 is a little too pricey imo
 
I saw an ebay listing for $45 but the triode balance was 2%
 
 
EDIT:
I've think a sturdy pair of 3D glasses lenses can make a great color filter.  There are also science kits that come with sturdy materials that won't melt under heat.

Forward mids=Voskhod or Gold Lion

Ok, I've had about two weeks of daily use out of my Aune T1 with the stock tube, and figured it was time for my review on this badboy with my WS99.

 
Is it ok if I add your review to the T1 information post (http://www.head-fi.org/t/633006/aune-t1-usb-tube-dac-amp-discussion-thread-see-first-post-for-faq/2010#post_9502294)?

+1. I would also add Siemens 7DJ8.

Sure thing! I hope it helps others!

Amperex OG (GAC, Heerlen), Siemens PCC189 or JAN Sylvania 6922 maybe. Although I don`t really understand what do you mean with foward mids? All those tubes I suggested have very "liquid & dynamic" mids section and it certainly isn`t recessed, Amperex OG (GAC) and Ultron SQ PCC189 have best mids section out of my tubes. Siemens PCC189 is also very good. Sylvania is with largest soundstage out of them and other two have "same" & "middle, sweetspot" sized soundstage.
 
Another mod I`m probably going to do is wooden (oak or cherry) ring with better scale around vol knob because I tend to listen on certain levels and those dots suck for setting proper volume. Also maybe doing tube guard. But first I have to finish my HD-662F wood cans (elements are only thing left from original HD-662F) ;P

dt880 has recessed mids, and the extra clamping of the pro does not help bring the midrange out lol.

This looks relatively cheaper:

Yes. Why not? Afraid of flames? Lol, wood is used even on table under really hot pans etc. That tube will never ever get that hot to even "burn" any dark spots to wood. My speciality is design/woodwork

I was just curious. That sounds great!
I just finished a prototype ring guard adapter using acrylic. It looks great with the LED on.
This is a very unprofessional mobile phone pic but you get the idea.

Nice! For me it`s too "futuristic" but it`s great work!

Yep rocket logo. I would rank these three tubes in question as follows:
 
Performance: Siemens > Genalex > Voshkod
Price: Genalex > Siemens > Voshkod (I paid $10 for a set of two rockets)
Overall: Siemens > Voshkod > Genalex
 
Many people seem to really like the gold lion and it's indeed probably the best new production tube. It's nice smooth forward sounding tube, but the $35 + shipping is just too high price for a tube that is essentially a upgraded rocket logo. More refined and extended rocket. I'm willing to sell my mint condition gold lion to anyone interested (living in Europe) just PM me and lets work you a deal you can't pass.
 
Siemens, in my opinion, is a very nice tube and you can get them relatively cheap from German sellers if lucky. http://www.ebay.com/itm/4-x-Tube-PCC88-SIEMENS-7DJ8-Suit-ECC88-6DJ8-6922-Akin-Cca-7308-E88cc-etc-/321185693288?pt=Vintage_Electronics_R2&hash=item4ac828be68

I don`t have Voskhod or gold lion but I can also recommend Siemens PCC88/7DJ8. It is warm sounding tube and mids are certainly great but I recommended Siemens PCC189/7ES8 before because it has larger soundstage, more air and clearer more transparent sound.

I'll try to get the Siemens, though most listings I've seen cost more than what I spent on the Aune lol.  Thanks
 
I've read that the Musiland 02 uses the same DAC as the Aune T1, though I've noticed the signature is quite different.  I might have to keep the Musiland if my replacement Aune sounds cold and bright.  In this case I would not even need to buy more tubes haha

Of course - they may have same DAC chip but tube is the point of Aune T1
 
Siemens PCC88/7DJ8 should definitely save you from "cold & bright". You just have to keep eye regularly on eBay offers. I got my Siemens PCC88 dirt cheap

Yeah there are some ridiculous asking prices out there. Just keep your cool and wait for the fairly priced one. If the prices are constantly very high then go for either voshkod or genalex. Genalex is ultimately better but also more expensive (better for general use also). If you are interested of the voshkod try to get one with rocket logo only. There are all kinds of reflector and cccp labels, but I can only vouch for the one with rocket logo only (http://www.ebay.com/itm/2-x-6N23P-E88CC-6DJ8-6922-DUAL-TRIODE-LOT-OF-2-NEW-TUBES-NOS-/390531162860?pt=US_Radio_Comm_Tubes&hash=item5aed78a2ec).
 
And try to keep those wise man Coil's words in mind and don't forget to include that Siemens 7ES8 to your searches. This being said I'm curious about the wider soundstage thing though. For me one of the main reasons I like the Siemens 7DJ8 is that it has this focused soundstage and awesome mids. It creates engaging and intimate feel which goes especially well with vocal centered minimalistic songs.
 
Happy hunting!

Couldn`t said it better! Spot-on description. But I want to point out that this "focused" doesn`t mean small or narrow, quite hard to explain for me.

I'm from China and Aune is a great HIFI company which can be dealed with.
