Looking forward to those XC impressions. Comparisons between the LCD X and LCD 3 are most welcome (although its closed vs open design). Would be good to find out if the XCs are essentially the X with a closed design or if there are any voicing differences.
Since this is essentially a portable headphone, at least for me, I'd like to know which portable amps work best.
Thus far the impression I get from reading earliest reviews is it's less darker than the LCD3s, so should pair well with the RSA 71B.
The 3s have great synergy with the iQube V2. Not so great with the 71B.
