Howdy! I love my Sony v6s and my Grado sr80s. The Porta-Pros aren't balanced enough for me (too bass heavy). I've considered modding them, and I probably will at some point. All of my listening will be done at a desktop, with my headphones amplified by a Focusrite 2i4 interface. Anyway, I'm looking for something new. I don't have a preference as to open/closed. I want something that's fairly honest, as I use my headphones to check my audio recordings and listen to music. I just want to check my mixes on a bunch of cans to make sure there's nothing that I'm missing with my current setup. My musical preferences stem around acoustic stuff, singer-songwriter solo work, rock, classical, and indie electronic stuff. I'm not a bass-head, and I don't really do the whole EDM/rap thing. I'm looking for some recommendations, provided you guys have some to give. I don't really want to jump to the $100+ level, but I'm starting to think that this is really the place where I'll start to see more noticeable gains in SQ from what I currently have. I just want something that I'll enjoy. I've been considering the following cans: AKG 240 - $80 Superlux 861 - $30 Koss ProDj100 - $40 Sennheiser HD 558 - $140 (I would probably mod them to to sound more like the 598) I've tried the m50s and I found them unsuitable for me. They were okay comfort-wise, but I didn't like their whole warm mushy sound. They didn't have the more detailed sound that the v6s have. I've tried the senn 280s and I hate their hollowed mids. Can't stand them. I've also listened to some beyer 990 pros, which are okay but the treble is funky. Too metallic sounding or something. I want to try some AKG cans, but I haven't had an opportunity to listen to a pair. I'm not quite prepared to jump on anything just yet, but I would like to have an idea of some particular cans I can hunt for. Thanks for your time!
