Ten days since I received my X2's and after a guestimated 100 hours of use and/or burn in, my latest impressions.
Overall tonal balance is still improving,
bass has really tightened up f.i. O'Jays: For the Love of Money, very rarely colouring a bit too much on low-fi recordings.
mids are natural and well centered and lush,
treble: a bit more dependent on source: mostly good, occasionaly a bit too velvety/rolled off, never sibilant or fatigueing.
The soundstage is simply stunning, timing is dynamic.
And I can listen for hours simply bathing in their lyrical presentation.
My music ranges from low-fi fifties & sixties jazz/ blues/ pre-soul / r&b and rocksteady to soul// ska/ reggea/ funk/ underground/ psychedelic rock/metal & classical.
The X2's have proven to be a great allrounder.
I am listening ALAC 41kHz/24bit through my Audiolab 8200CDQ, mostly on Optimal Transient XD filter setting, because of the almost analogue sound reproduction, great timing & superior soundstage through this filter.
This filter is measured for early highs roll-off & bad alias suppression. The combination of the X2's and Optimal Transient XD is responsible for early treble roll-off @ f.i. Grinderman 2 - Palaces of Montezuma.
Despite all that i keep coming back to this particular filter, it has this magic fairy dust.
Same goes for the X2's, they are not entirely linear in their reproduction, but so musical / lyrical, you are hooked.
