Hm, do you know what is the difference between these Mullard tubes and the other ones (in blue box) available from the same seller:   http://www.ebay.com/itm/6080-MULLARD-NOS-BOXED-VALVE-TUBE/311478749131?_trksid=p2047675.c100005.m1851   I found report by someone from head-fi that they...

Hello,   I've read in original Elise thread that this amplifier is  SE OTL type.  Is this really the case? I ask, because there is no mention of word OTL in Felix Audio  Elise  page.

Transcendent Sound is well known for OTL amps for speakers. This is the first headphone amp offered by Transcendent Sound (Bruce Rozenblit). Anyone tried this?   http://www.transcendentsound.com/Masterpiece.html

There is very little info about Creative Aurvana DJ cans, but I think they are differnt from CAL.   Creative Aurvana Live! uses Foster 399317 driver.   CAL technical blurp reads like this: Driver Units: 40mm Neodymium magnet with composite bio-cellulose diaphragm Frequency Response...

It seem that CAL 2 uses the same Foster 33917 driver (http://www.head-fi.org/t/694472/lightbox/post/10052487/id/991973) as used in original CAL.   So I don't see a point of paying almost double the price for CAL2.

I can get both them locally for the same price. Which one should I get?

Maybe someone who has s400 heared  JVC S600 or Creative Aurvana Live and can give some insights?

Hello,   Maybe somoene heared both theese cans and can compare sound quality/signature of theese two headphones?
