Lol.. same for my brand new 650 with custom can mods.. sigh..It's the ECP Walnut 5 DAC. Love it - sounds great! Warmer, smoother, more analog-like than other DACs. Not gonna compete with my big turntable back home, though haha.
I'm progressively more impressed by these ES R10 after comparisons to the re-cabled Sony SA5000, which again I really like (and am so sad was discontinued - this should have been more popular than the HD800). I think the ES R10 asserts its dominance with a sound that's simultaneously cleaner and more natural. It might not be a headphone that leaps out the box and grabs you at first listen, but it will creep up on you. Really nice articulation and space around instruments. There's even some bass slam too!
Very low listening fatigue factor on these. Physical comfort is excellent as well.
The HD650 is still on the floor, where it belongs now haha.
I would not have been as wowed with the ES-R10 if I had listened to them out of the 3Max - WA8 combo too.. thankfully there’s extremely good synergy with the Diablo.
I haven’t been able to bring myself to listen to my other headphones.. not even my beloved 800S. The wife is happy though cos she can’t hear me blasting music thru the night now
