Anyone heard Nuforce Reference 18's


I am interested in reports about the Nuforce Reference 18 mono amps,particularly in comparison with Nuforce Reference 9 V3SE's which I currently am enjoying.
Thanks

Update from CES..Nuforce has informed me their new Reference 20 mono amp was premiered at CES. It look's identical to the Reference 18. Larger power supply. The rating is 360 watts rms @ 8ohms and 420 watts rms @ 4ohms. Late February/mid-March release date. Price is confirmed at $ 9K a pair.
Bob in tech support at Nuforce was at CES and informed me the Reference 20 sounds more relaxed than the Reference 18 due to its much larger power supply which can drive much larger speaker's than the 18's with less strain.
Summitav, do you know yet what the upgrade cost is to Ref 18 owners? I would think it would be a percentage of the $1400 not the full amount.
