Sorry Jaffeassc, Let me address your original question with respect to my paragraphs above, and also try to answer your last question.
First - when driving the Mani-2 with 100 w/c, they sounded great. Would I buy them based on what I heard? yes. I was very happy with the results on one MF2100. Incidentally, I had driven them with an old Bedini 100/100 that I have in my other room too. It's pure class A and IMO did a little better job of controlling the bass. One Key point about the Watt rating - the CJ MF2100 is rated at 100 w/c at 8 ohms. I don't know what it's current capabilities are or its power rating at 4 ohms. Same for the Bedini.
As for the B&K M200s - they are rated 200 w/c at 8 ohms, and are current generators. 150 amps p/p, so you get the full 400 watts at 4 ohms. That's the power rating I referred to, and I assume Baroque also referred to.
So, I think the message for you is this, I think the 9100 will give you nice results, actually excellent results for now. When you're ready to upgrade to a new power amp, you effectively get a new set of speakers without having bought any. Finally - the Mani-2 just begs for Bi-amping. A nice upgrade path would be to get an outboard power amp to drive the bass, and drive the M/T with you inboard amps.
As for what I hear now - keeping in mind that what I heard before was pretty phenomenal compared to other speakers I have or have had, including - Totem Sttaf, and GMA Europas, Von Schweikert VR3s.
I hear much more control, precision, and resolution of tones. The bass is tighter than I could imagine. The mids and treble are crystal clear. This opens up the soundstage. Instruments are more pinpointed in 3 dimensions. These are all things I would have said existed previously, but now it's just more.
