mr speakers ether 2 is magneplanar right? They tend to have that kind of soundstage. I don´t get that with my HD 800S. For sure my tube might go a bit deeper and since headphones always have to small soundstage who to say it´s not more realistic but I don´t sense a particular problem at all with the THX 789. I happen to like it intimate but the HD 800S still go decently wide. I have not really compared the actual width to my other solid states but it´s not much between them.
