Uhhh. Wouldn't the MG Head alone go considerably over $250? If you like Sennheiser, look at thr HD 590s. They have lower power requirements and might suite your taste better than the 600 anyway. They are siad to be less laid back and more dynamic. I tried them with no amp for an hour or so at tweeter (cheap discman as source, but my music) and they were qwuite nice. I listen to a lot of electronic music as well, and I think they would do fine for you. The most you should pay for them is $175, beucase that's what meier-audio charges. You can get them as low as $150 new from some ebay shops, but I can't vouch for those. Inside the $250 budget, a cheap amp such as a meta42 might be good too. I haven't heard any amps yet, so I can't give you too much help. I have however heard the V6 twice, so I know what you mean. I don't think the bass an the 590 vs the V6 is still hard for me. I think the 590 is better, or at least will be better with an amp. The V6 has pretty good bass for unamped use, but it seems bloated. However, you had said that the bass was second to the mids and highs and I think the 590 is well above the V6 in any other catagory, especialy if you would like an open phone. Comfort on the 590 is to me, WAY better than the V6. It has the clamping that people talk aout with senn phones, but it went away pretty fast for me and I was left perfectly comfortable and knowing that there was no way they'd fall off. I'll bet you could use the 590 in a gyro gym. (Techno anyone?) Have fun, see if you can try some things out. Even trying one or two good phones other than what you have will give you a good referance point for when people make direct compairisons. Have fun!
