A friend of mine has a room with the same dimensions as your's and he is using the Super Eclipse III. His associated equipment is a CJ 17LS2, Bryston 4BSST, VPI Aries I/Graham/Benz M2. The sound is very good. Very dynamic and with excellent bass. I must admit I think I preferred this system when it included the Quicksilver V4 amps (tubes) but this is a matter of taste - my friend prefers the Bryston. I have only heard the Cremona at the Montreal HiFi show so no useful comparisons in this regard can be made. Still, the Cremona is also very good.
Your room is not big enough for the Total Eclipse - don't even consider it.
