i listened to them in a store , i listened to them on my xperia mobile , they had a very OK bass
would they sound much better with my choice DAC/Amp (Creative Zx)
would they be uncomfortable like portable closed phone (making me sweet and burning my ears)
1- Yes. This are really bright headphones. DT880 sound smooth and neutral in comparison (And DT880s are also quite bright headphones)
2- File quality has nothing to do with recording quality. File quality is not that important as far as you use (Good transcodes) at least 16bits/44Khz lossy files.
Recording quality is maybe as important as headphones/speakers quality. Most audiophile recordings shine with this headphones. As a reference:
Vivaldi - The Four Seasons - Seiji Ozawa - Boston Symphony Orchestra (TELARC)
Tsuyoshi Yamamoto - Autumn In Seattle (XRCD)
Anne Akiko Meyers - AIR - The Bach Album - English Chamber Orchestra
Zhao Cong - Dance in the Moon
Diana Krall - When I Look in Your Eyes (Verve)
Mstislav Rostropovich - Bach Cello Suites
Most recordings by Chesky Records and Harmonia Mundi
Dynamic Range is often an interesting parameter. Here you have a good database:
Most modern recordings are compressed and don't have good dynamic range. Some headphones are tuned to give their best with modern (non audiophile) genres/music. Definitely not the case of DT990.
They will sound better with good quality DAC and Amp, but differences in my experience are not that big in terms of frequency response. Purity, soundstage and detail are often the most clear improvements.
Confort and fit is a pretty personal thing, being fully open cans with velour-like earpads they don't feel like most closed back on ears which are designed to provide good isolation. Despite this are not as confortable as HD598 and DT990 they aren't incomfortable to me, but again this is a pretty personal thing, maybe someone with big head and sensible ears could hate this kind of headphones.
