More linear meaning more sub-bass, with better bass extension, along with smoother upper mids/treble with even more top end sparkle/sizzle. Imaging is also much better on my T50rp, which is due in part to the narrower, but deeper soundstage. The isolation is also very nice right now since it's summer and my window A/C unit is kind of loud in the room where I do most of my listening. I don't plan on selling my Q701 though as it still has it's place in my small and limited collection.
I don't know why but closed headphones always seem to have better imaging. The Q701's angled pads also seem to hurt imaging compared to flat pads. I think this is why the K601 seems to have better imaging.
Whenever I want slightly better low bass I just use my HD-650 or DJ100. The Anniversary pads don't really do anything in that area for me.
I was unfortunate to have the only un-moddable T50rp. Perhaps it was a lemon but I wasted hours and hours on it and never got anywhere. I don't even want to know how much money I spent on ridiculous modding materials. I worked on it so much that I even stripped 3 of the screws due to all the opening and closing of the thing. Luckily this was back when they were only $75.
I'd really like to compare a fully modded T50rp to my DJ100 at it's best. I remember getting glimpses of the T50RP sounding good but I had to do such weird things to it to get there.
I've been using the Q701 a ton lately with the E17 as a DAC with L7. Modi is better as a DAC but it's a little fuller sounding with the E17. I use my E17 a lot with my Xbox 360 and Q701. Seems to be good enough.
Don't sell the Q701 ever, you'll probably miss it within a few weeks if you ever do
If someone offered me like $500 for mine right now I'd say NO WAY! Yeah i 'm that attached to it.
