i have not heard the esoteric or super high grade teac electronics for a long time, and it has also been quite a few years since i heard the cremona m's
with that said, i would venture that pairing accuphase with this speaker will be quite warm and very smooth up top thru the mids, with quite a bit of midrange 'bloom', and strong bass response.... relative to 'dead neutral' i would suspect the presentation to be definitely on the 'dark' side... which may be a positive attribute for a listener if they have a lively room or they like the music uber smooth and rich sounding, if perhaps at somewhat at the expense of a great sense of transparency and air/sparkle to the presentation
