The way I see it, there's a slight difference, yes. But a small frequency bump won't change the fact this is a downright amazing headphone, very high resolution, tactile and well textured bass with great decay and speed, smooth and well extended treble with 'stat-like' performance, a realistic and present midrange and best of all, a large but not too distanced soundstage with pinpoint imaging. That's what I've gathered from reading about this headphone for a couple weeks. This headphone is a great value at 900$, great comfort, value and sound.. what more is there to love? Easy to drive as well.. there's no doubt in my mind this is one of the most versatile and best headphones that's presently available.
Well, the hype is strong with HE-560 as it was with LCD-X and PM-1... Rather wait with these 'worshipping' statements/judgements.
