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. 

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

Quote:   Nope it says awaiting shipment so they haven't even shipped it, on the 29th Jan they said 1-2 days will be shipped but yeah nothing since then order status hasn't changed and no reply to my email I sent day or 2 ago, so far its been a pretty bad first experience with them...

how long does upscaleaudio generally take to ship products purchased the amperex 7308 on the 25th and still not shipped, anywhere else that stocks the amperex 7308 and actually ships items faster?

Quote: Good thing i decided to go with the Amperex 7308 might consider buying a few as backups just sucks that postage cost so much to AU almost as much as the tube itself.

Quote: That was the only option available :(

Quote: I went with a Amperex 7308 set me back $142 ($54 delivery). Knowing me though I'll be purchasing new tubes every week just to test out lol.

Quote: Accessoryjack have them for $386, DWI have them for $365 via there ebay front not sure if they ship to your location: http://www.ebay.com.au/itm/SALE-BRAND-NEW-SENNHEISER-HD650-HD-650-ON-EAR-HOME-CINEMA-HI-FI-HEADPHONE-/330852972628?pt=AU_headphone&hash=item4d085fb854

Was about to edit my post dunno how I missed it on first post.. prolly time for me to go to bed 4am here. Thanks anyway :) will be ordering a few different tubes soon as I wake up.

Hey guys I ordered my Aune T1 and should be receiving it this week, I'm just curious does anyone know a good online source for NOS 6H23's (rocket logo), Also are there any other recommended tubes wouldn't mind trying a few :)

Quote: Hey thanks for the reply, the schiit modi / magni combo cost $330 here wish I could get them for $99 each, The O2/ODAC also cost about $340, while the Aune T1 with russian military 6H23N-EB tube is $250 kind of leaning towards the Aune T1.

Hey guys new to this forum and just after some advice for an dac/amp for my HD650's that will be arriving later this week, I'm thinking of going with either O2+ODAC combo or Aune T1 + Russian Military 6H23N-EB tube, This will be my first set of decent headphones so I'm just trying to purchase...
