Thanks for the replies.
I can live with 20,000 hours for the cost of a tube. I'm gonna leave that thing on 24/7 so I can enjoy it to the fullest. I'll do some research on wrapping it, etc.
Finland, but it seems i posted this too hastily. Tried different tubes and E17 and they all had the same rattling sound. I located the problem to be my usb port not the T1. It seems that I cant have anything in the port next to amp usb port or there will be rattling distorted sound. Don't really know what causes this but at least its working now that i have removed my other usb connections.

Scroll down a bit, there are pics of the manual posted by Salvatore (sp?) on Oct 18, 2013 at 2:13 pm showing how to change the gain
Dont know how to re link/post that particular image here
Comfort loudness on 50% volume now. it enough? 0db
Manual and gain settings along with all other useful info can be found in first post faq and the useful posts link.
Is the cap upgrade within the DAC portion or amp portion of the circuit?
The USA one should be stamped 110V 50-60Hz. Your power in the EU is probably 220V 50Hz, so you would need a step-down transformer to take 220V to 110V, and also an adapter to plug the USA transformer into.
You can usually get a converter which will do both things at once... the converter will have a wattage rating, and the Aune adapter only puts out 1A at 30V, which is 30W. I would go for a 100W converter minimum myself.
To summarize, just make sure the USA Aune transformer is being fed with the right voltage (V) and the right frequency (Hz).
There are four sets of caps that I replaced...
Two sets of caps are for the power supply circuit inside the Aune, which I imagine should power both the DAC and amp. (I would need to see a schematic for the T1 to confirm this). The other two sets of capacitors are on the headphone amp board.
As for the capacitor #'s, I have them written down somewhere, but I can grab them for you if you like (If you open up your T1, you'll see the printed circuit board has C## printed beside each cap, so they are easy to reference). CoiL also has a lot of information... he did the upgrade first and recommended it to me.
