Yes, the HD700 has a good sound stage, but for the price, I don't think they're really worth it. Back to the topic of HD650 and Hd600. I tried both headphones , and I kind of leaning towards the HD600, I am quite confuse after hearing reviews of the HD650 but it sounds harsh to my ears, the upper mids and highs feel rough to me while I can't really hear the sound stage different. Perhaps because I was running them with cheap FiiO E12 Amp. But it should be enough. I am really in the market for open-backed headphone that has very huge sound stage(for movie) and good bass impact. If somebody can help me to suggest different gears to try. Music that I listen to is just about anything, but mostly are Classical, Jazz, Rock(Coldplay, Linkin Park), Instrumental). such example of headphones that I like is Sennheiser Momentum, Sony MDR-1R, HD449 Sennheiser. Someone please help me.
