Tda2200,
Just a quick quote from John Atkinson's original Cremona review back in 2004:
"However, the pianos on Soular Energy and Reptet occasionally had a little more bite than I was expecting; some notes sounding more forward in the soundstage than others."
This is the same kind of thing I recall hearing when listening to the original Cremonas, and since I am so sensitive in the midrange and upper midrange regions, it bothered me. The M's have tamed this, which is probably the main reason I like them better.
You are refer to the hotter treble in the M's. I do not disagree with you here. The M's definitely do have more energy in the treble region, as shown by the response curves referenced by other forum members here. My ears aren't quite so sensitive in the treble region, so I guess that it just doesn't bother me. Perhaps the up-swing in treble response is what is making me think that the M's are a bit more detailed and "lively" than the original Cremonas.
I actually just heard the M's again last night, at Stuart's A/V in Westfield NJ. They really weren't all that well set up (the room a bit small and highly reflective/echo-ey) and were being fed CD via a Sony BD2000ES Blu-ray player though a Macintosh integrated amp), so they were not performing at their best. At least in this room, I definitely noticed a lack of bass weight, as some others have reported. From my own experience, I've found that good bass response tends to "smooth" the overall sound of a speaker, actually helping to mask flaws in the mid-range and even appearing to tone down the treble as well. I would certainly not characterize the sound I heard as boomy or slow though. Drum attacks were very quick, and had the appropriate "thwack" that they should. Despite the limitations of the room/equipment, I still enjoyed the overall sound of the Cremona M. I'm a bit of bass junky, so I would still feel the need to pair this speaker with a tight subwoofer to fill in the bottom end a bit.
They actually had the Elipsas in the same room, being fed by Mac SACD/CD player, MAC pre-amp and amp, and I definitely preferred those. Granted, they were a bit (just a bit) bloated in the bass due to poor positioning, but the potential was definitely there. A sub is probably not necessary with this speaker. Shame I can't afford them. The Elipsas are also much smaller than I thought they would be. Really impressed with this speaker, but cut my demo short as there is no sense in torturing myself with things I can't afford.
They had the Auditor M's there as well, but due to time limitations, I didn't give them a listen, as I've heard them before. Plus, they will be relegated to surround duty in my room, so I'm not as worried about them. I haven't heard the Elipsa Auditors yet, and they may make for a better surround speaker due to wall placement options.
I also gave a listen to the B+W 802D's while I was there. These were in their dedicated theater room, which was treated to sound pretty darn good. Again, all Mac gear driving them. Very nice speaker. Shame that they cost even more than the Cremonas now. For my ears, they had a tiny bit of excess energy in the presence region, but I think I could tame that with cable/amp matching or perhaps a touch of EQ.
I have to go back and get them to move the Cremona M's into the dedicated theater room to give them a fair workout.
