R10:
This headphone has the best midrange, ever. No other headphone that was here could match it. It's also the most detailed, resolving heaphone. With good recordings (any of the Patricia Barber Mobile Fildelity SACD's, for instance) the bass was all there and it was tighter, deeper, articulated, and more textured than any other headphone. HOWEVER - with average recordings it lacks as much bass as I'd like. Actually the upper range can get a bit aggressive too. It doesn't help how resolving these cans are. Jethro Tull's Songs From the Wood (using the old-chassis SDS) wasn't very listenable, honestly. Same with a old J-pop anime soundtrack I tried. Both these albums are very enjoyable out of the L3000. Later, listened to Jethro Tull's Broadsword and the Beast and Joe Satriani's Surfing With the Alien out of the SDS-XLR with balanced R10's. It was much better than before - very enjoyable, parts were just awesome. IMO though, that was just the amp's doing (amp is not burned in, BTW) - again, I think the L3000 is just voiced better for that type of stuff. Tom's Thiel CS7.2 speaker setup is even better still, of course - the resolution of the R10 with the enjoyability of the L3000
Also, the R10 are awesome for classical. Tonailty is just spot on. The Telarc Absolute Sound SACD was just incredible.
Omega II:
I have yet to find my happy place with these. They still can't do rock at all IMO. Even on vocals, classical, acoustic etc, which is more its game - they're not good enough to outdo or even match the top dynamics. Not enough guts or slams or muscle for rock. Drum hits sound spitty when they should either *thwack* or *thump* or *thud*.
L3000:
Everyone on earth should know my thoughts on these by now
Qualia:
I really like these, which is quite a surprise to me. I don't think the other guys share my sentiments
Honestly I'm still not sure what I like so much about them. I actually found the R10 midrange to be more detailed. Tonality also seems a bit "off" and can take some getting used to. However, once I got the fit right (can be a bit tricky - see pics) and gave my ears some serious adjustment time to get acclimated to them - they render a very pleasing, musical image. They're not something I'd listen to acoustic instrument solos on; vocal solos no way. Really like them for music where there's a lot of stuff going on though
The Absolute Sound CD was also very enjoyable on these - some tracks I found myself liking them as much as the R10 :eek They kind of started to dissapear and just serve the music, in a few instances. I have my own set on the way, actually.
