This year and last year I had the opportunity to see and listen on several occasions to the MBL 101E Mark II speakers - essentially half of the 101 Xtremes atop single subwoofer. These speakers are drop dead gorgeous but its good looks are surpassed only by its exquisite sound quality. Every audio show I was at this year and last year MBL had long lines of eager listeners waiting to hear these speakers for good reason.
As tremendous as the 101E MKII are, the 101 X-Treme just takes things to another level. I heard these speakers at CES this year and what I experienced was astounding - closest to the live performance I've yet heard. Yes, they are expensive and not for everyone's pocket book, but for those who can afford them, they are well worth the price of admission. This is an instance where one really does get what one pays for. State of the art in every way.
I aspire to one day own MBL's more affordable Corona Line which also has superb build quality and stellar performance. The speakers, stereo and mono amps in the range are really something special.
