I think HD700 is a truly great piece of work, it however needs to be used cautiously. HD700 excel so very well in certain type of music, such as jazz and classical, but can be very unpleasant in others, such as modern pop music. The way I see it is that, Sennheiser specifically designed this headphone to be excellent in some types of music at the expense of being able to do well for everything. In my particular case, I find that I always need to keep two set of headphones around me, HD700 and something that is "fun" to listen to, something that gives a very punchy bass and can drive any type of music just fine(key word is "just fine").
PS: I have been listening to HD700 with my Modi+Bottlehead Crack set-up. If anyone has suggestions for upgrade tubes(prefer warm, recessed treble ones) or DAC, please let me know :)
Yes i think i agree with this. I never hear to any jazz or classical music or acoustic, just modern pop music and some r&b. To me it's not worth the retail price tag. I paid just 299€ for it so I'll keep it because it still beats other phones around 300€.
