Anyone able to compare the 660S2 to AKG K712 in terms of overall tonality, sound stage, and transient response?
In general I'm trying to get a sense of how the overall sound relates to the cans I know and love - I've got a pair of HD650 that have made it from not long after their introduction 'til today with some minor refurbishment along the way, love their sound. Love the HD660S, more energetic and revealing plus they respond very well to EQ. From AKG I love the Q701 and K712, my go-to studio usage cans (when I'm able to use open headphones for a particular task) that offer different looks but share some strengths. Also still enjoying some of the older 250ohm Beyers, even if they aren't the current hotness I'll defend the 250ohm DT-770 as an excellent closed headphone that can hang for studio work
Last but not least ATH-A990Z, mainly for movies & gaming as they have some nice attributes for those usages while not being especially "reference" quality.
As mentioned I am not averse to EQ and make plenty of use of the EQ in my Magni+/Modi+/Loki Mini+ stack of Schiit. While it is certainly true that trying to move headphone drivers out of their design parameters can lead to unflattering distortion, some of these headphones tolerate pretty big moves very well and I have never felt the 660S are bass light with regard to their ability to be EQ'd for more thump where I want it.
I'm wondering if I have any pressing need for a set of the S2, or if I can wait around a bit 'til they come down in price - $600 is steep for a set of cans for me, even if adjusted for inflation I paid more for the HD-650s back in the day the competition is stiffer now. I wonder what the 660S2 would offer me that I need.
