So I'm trying some different audio equipment to decide what I want to keep.  After listening to my HD 600's for a day on the Vali my ears hurt and there was ringing.  The next day my LCD-3's came in and I listened on an Audeze Deckard.  Ears recovered and ringing went down.
 
Decided to try my LCD-3 on the Vali after a day of listening on the Deckard & immediately I noticed something that felt between pressure and sound on my ears (it's the same feeling I get with noise cancelling headphones).  I really loved the sound signature of the tubes with the HD 600 (almost as much as my LCD-3 + Deckard).  
 
Has anyone else had this issue?

how long are you letting tubes warm up for? I found with both my Vali and Valhalla, that decent amount of time is needed for tubes to warm up and produce the best results. I found listening to tubes cold can be awfully fatiguing quick. I let my Valhalla warm up about 30-60mins before a listening session and no longer get any fatigue.
