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

I feel a little embarrassed to ask this question, and I will explain why. Simply, in my 50 plus years at this ( as an audio professional and consumer / hobbyist ), I have opened every amp I have every owned, to do a mod or 2 of some kind ( everything can be modded, for improved sq ). Has anyone been under the hood of the STA 200, as I have a few mods I would like to do. Removing the 4 philips screws from the rear side walls, I would think you spread the side walls, from the rear where the screws were removed, to loosen the top. I have tried, very gently, but they did not budge. I did not want to use excessive force. Nuforce has not answered my emails, as I suppose they do not want me in there. I would appreciate any response. BTW, as I have said before, this amp does so much right, musically, that although some amps might be better in 1 or 2 ways ( through a particular set of speakers, due to efficiency / impedance ), this little amp is quite the beast. I have owned AR, Krell, CJ, Threshold, Bedini, Ampzilla, you name it. Amp sounds best on a non resonant shelf, being left on continuously with signal playing through it ( a few hundred hours ), an after market power cord, and a 1-2 lb weight on the top center ( I use a thinking man statue over a padded piece of 4 in. X 4 in. piece of granite. Enjoy ! and Happy Holidays. MrD.
Can't help you open the case.

My purchase of the amp was necessitated when one of my monoblock amps blew out. I was looking for something that was relatively inexpensive that would hold me over until I could figure out whether I was going to purchase something in the price range of a Bryston 3BSST, Simaudio W3/W5, etc. To my surprise the damn thing sounds as good as others have commented and with my modest apartment it drives speakers as loud as my neighbors can stand.
I bought one of these probably about a year ago. Haven't tried it yet. I bought a Schiit Sage preamp to go with it. Has anyone tried the Saga with it? I've been wondering if the gains will match each other.
The Saga and STA 200 work well together. The input gain on the amp will easily allow you to use the Saga in passive mode, which I prefer over the tube stage. It is of course personal, and you might like the added color and roundness of the tube sound. Note : It also has to do with your source's voltage output and power supply design, when using it in passive mode. Enjoy ! MrD.
Thanks, MrD!


I probably won't use my system until I have the room ready. And that could be a while yet. But it sounds like this STA 200 is really a nice sounding amp, regardless of price. I have a Freya on my main system, and love the adjustability of the Schitt preamps with the passive and tube choice. Some songs on my main system sounds more transparent and detailed with the passive, even though I use the tube section of the Freya more.
