Nuforce STA200

I am curious about the Nuforce STA200 amplifier  If anyone has experience with the amp it would be appreciated if you would share your listening impressions, both good and bad.  Some of the descriptions I have read classify it as a class AB amp and others a class D amp.  I am not technical savvy about these things, can a single amplifier be both? 
Thanks

Jl35, that is good to know. The speakers I own are rated higher than that, however do drop below 4ohms in the bass region. Phase angle at these frequencies is benign however. In what size room is your system?

smallish room, about 12x14...I think the amp is fine into 4 or 8 ohms, as long as it is looked at as a fairly low power amp, which is what it was designed as...many amps put out same or similar power into 4 or 8 ohms, such as McIntosh...

I think it's the preamp match which is difficult...

Luminous Audio Axiom ii passive preamp works great with this amp.  I use one, and I think another poster here does as well.  Dead quiet even with the STA-200’s high gain.
