my vintage receivers are close to my woo with the LCD2.
Theres a difference, but its not huge.
Mainly soundstage/imaging, dynamics and a little bit of extra detail.
again these difference aren't big.
do you plan to ever use speakers?
price is really the other thing to consider.
if i weren't obsessed with audio, if it weren't an addiction, I would be very happy with my 2245 that ive been slowly recapping, to power both my speakers and headphones. Its sounded great with everything ive plugged into it, Beyers, Senns, Shures, Audio Technica, Fischer, ect.
