Completely off topic- but I'd try to listen the Cerious Reference as well. Ken at LaserCD who posts here has them and thinks they are better than anything he has ever heard at any show (and a bargain at 20K)
He is by Princeton NJ, and seems pretty willing to let people hear them.
I am a huge fan of the MBL 101's (though it has been said they hard to drive) and have heard them many times over the years at the NY shows, but after hearing the Cerious Cables in my system, I really think they are onto something. I'll have the smaller Cerious speakers here soon, and will post my comments. If I really like them, I'll try and swing the references with the next year.
Just reading their technology makes me drool, and think that most other speaker manufactureres (obvoulsy not MBL or Kharma) are in the dark ages compared to what Cerious is doing.
I asked Bob at Cerious if he ever considered using the Diamond tweeters in the reference, since I heard B&W's diamond tweeter line, and was impressed with the treble part of the spectrum (not the rest though)
Bob said he had in fact played with diamond tweeters in his reference, but that they always sounded good, but discontinuous with the rest of the spectrum. This is exactly what I heard with the B&W's, FWIW. I have never heard the Kharma line (but would love to) but have read comments on the asylum mentioning they are highly overpriced.
Please post back if you get to hear the 101e's vs. Kharma's.
