Looking for some open headphones around $200. I prioritize soundstage and neutrality. I currently have no amp, but that may be a future purchase. I like lots of music, but mostly classical and indie-rock. The headphones I have been looking at are the Sennheiser HD 558, the 598s, the AKG 701. I've decided against the Audio Technica AD900 because of the headband. Any other appropriate headphones in this range? Or is there a preference between the ones I listed?
Without an amp, the HD 598 is the best choice. The 558 may be the best value at current prices.
