Yes I found the k612 very bright and harsh at first and I regretted buying them. They hurt my ears and I couldn't listen to music. They were fine for gaming though so after 3 months of gaming and occasional music they seem much nicer. Highs no longer kill my ears and now I'm listening to music...

Why do people say the amp for Aune T1 isn't so good? Because of how it sounds? Or because it isn't very powerful?   The specs I've seen on the amp looked pretty powerful. 400mw at 120ohms which in my head is rather decent power

  Got my refund.   How about this one? This what I'm looking for? http://www.ebay.com.au/itm/ECC88-6DJ8-Made-In-Holland-/121714725638?

You guys have some serious knowledge stored away in your heads. Thanks, will ask for refund :)

Pics came through from seller:          

  Finally got a reply back from seller about other options.   ----------------------------------------------- One 6DJ8 I have on hand was Holland-made, probably same factory as Amperex, but it also has a Mullard code near the base. What's more, it's branded by RCA in orange print. I believe...

I bought this tube http://www.ebay.com.au/itm/Vintage-Amperex-Holland-Bugle-Boy-white-text-ECC88-6DJ8-preamp-tube-tested-65-/351293745274?pt=LH_DefaultDomain_0&hash=item51cabd287a&rmvSB=true   But the guy said he's lost the tube.   ----------------------------------------------- Hello...

While I wait for my new tube can I bypass Aune T1 dac and use Fiio E07k for the dac?   I just want to experiment what it sounds like using Aune amp and Fiio dac.   Since this is my first venture into the amp/dac/headphone world I might as well mix and match everything to try out different...

Bought the tube :D   Said it'd take about 2 weeks to arrive. The anticipation

I see eBay link for Amperex 1965 Holland says it's a used tube. Is that a good idea to buy used? How long are their lifespan?

I have AKG k612 headphones. I bought the Aune T1 for about $100 US and some tubes seem to be about that much which I can't afford. At the moment I'm browsing different sites trying to find a good tube for below $40 US that also ships to NZ. Seems a wee bit tricky to find

Sounds like a tube that'd solve my issue with highs :D

New Zealand haha, probably can't get anything here

Wow those tubes cost nearly as much as I paid for Aune T1

I have Aune T1 mk2 with 6922 tube from massdrop paired with AKG k612 pro. I'm finding the highs very fatiguing. I want a much more warm sounding signature with less bright highs. Is there a downside to just applying software eq? I'm using Spotify (Premium quality), and thinking of buying a...
