high end single box cdp's for redbook quality only

single box cdp's: redbook presentation only, other features are not my consideration.

esoteric x01-d2
wadia 781i
dcs puccini

requesting opinions from those who own or have auditioned at length any 2 of these 3 players in fully balanced mode.
pls do not shy from details of sonic differences, strengths / weaknesses in the range extremes,issues of top to btm fluidity, transparency, micro detail, forward vs laid back, btm end resolution, top end fullness, etc. all comments welcome provided they are based on your personal listening experience. i listen to a wide range of classical music, acoustic instruments, no electronica.

not interested in a/b with: wadia 581 models, esoteric x01 models other than the d2, arc cd7, emm, accuphase, meridian.

it is very helpful if you have your system posted or advise it. obviously, every system will benefit from a cdp that works to a system's strengths and lessens the system's weaknesses.

thanks kindly.
