what would you consider to be the best selection of headphones at about £600. The sennheiser HD700's have caught my eye with a great deal of people giving them a great review. Are there any obviously better alternatives that i have over looked at this price point. Also, i have a quote for a brand new pair of HD700's for £525, can you get much better than that? In terms of grado's i don't particularly think very highly of their build quality or rather they leave you wanting more (literally just paying for the drivers) although this is completely my personal opinion. I would very much appreciate any feedback you guys must have. My main use will be use with my graham slee novo headphone amp.
Thanks in advance
