Aune T1 USB Tube DAC+ SS Amp Discussion Thread ***See first post for FAQ--Updated on 02/14/15*** - Page 537

The tube is only for buffering and not actual amplification stage. It's not under a lot of stress and doesn't heat up as much as pure tube amps.
Even then, tubes are rated for several thousand hours. Basically means we're all good to go for a long time.

Joel,

I've had the Aune T1 for 3 years now. I still use the Amperex 7308 (1968 vintage) which I got after a short period of tube rolling. I now use the T1 as a DAC only and use a Schiit Vali2 (with a Siemens tube that you traded with me). Seeing that the tube is a buffer only on the DAC of the T1, I doubt that there is any change in stress because I am no longer using the T1 amp. I use this unit almost every day for the past 3 days for several hours each but the tube shows no signs of failure.
