 Which Tung Sol? pic or link?
 New tube sockets are Teflon which is a more porous material so the light shines through more. 
 Not today's tube amps. In the past tube amps were OTL (output transformerless), WA8 is transformer-coupled which has a wider range of hp impedance compatibility (8–600 Ohms). We still make WA2 and WA3 which are OTL.
Is the battery life truly too short or we're simply enjoying music on WA8 longer? My iPhone 6S' battery lasts about 7 hrs while my mom's flip phone can go for days without charging, but it doesn't have the same capabilities & usage enjoyment of my iPhone 6S. I'll keep using my iPhone and charge it when I can to make it through the day.  
 Congratulations! We recommend 100–150 hrs. of normal use with music playback to "break-in" the amp/tubes. The sound should improve with every use. :) We intentionally made the switches slightly recessed so they can not be accidentally switched ON/OFF in transport. Please keep in mind to power OFF the unit before changing the tubes output, this resets the circuit. We look forward to your extended listening impressions and pics. 
I wish there are more info on "USB DAC". What does that mean?   https://esupport.sony.com/US/p/swu-download.pl?mdl=HAPZ1ES&upd_id=10956&os_group_id=18   On my Z1es is shows this.   I updated the FW. Looks to be using an external DAC with Z1es. I wish I could tap into the internal DAC instead.    info from Sony: http://tinyurl.com/zhuyndl  
 Very nice setup and collection of headphones. 
We'll be at TAVES show with a BIG showing. Be sure to stop by our auditioning room.   
Look for us at the Eng Siang (AVone) booth.  
Look for us and Focal in our private listening room.
