My first major headphones was a Beyer 880 and its airy and detailed presentation matched perfectly with classical music. How's the soundstage of the T50P's? This would be like the ATHESW10Jpn portable version of Audio Technica's big cans. Congrats.
yeah I would agree, more of a crystal glass than a builders mug - it does feel high end, coloring it right now out of my s9 with BBE2 Viva and pushing good bass out it now.
I am actually thinking it prefers my s9 to my laptop setup - again the uDAC might be making it a mess out of the tonal qualities my cans when connected to the macbook on windows 7.
maybe switch to osx for more testing as it behaves in OSX

Sound stage I would say is bigger then most if not all cans in this portability class, probably more so than HD25 from memory which is what tipped me on this over the HD25 - though still after a HD25 as a bed buddy with the T50P.
driving well now on my s9 now at 32ohms

must mention the mids may... and this is subject to debate as we go on - be slightly recessed on the s9.
