I ordered a Nobsound 100wpc stereo amp on Ebay for use in my wife's dance area. For the dance floor I am currently using my old JBL 8340a speakers which are around 90db efficient. I hooked up my Pioneer BR player to the amp, and turned it on with the volume at zero, and then went to turn it up.. I just turned it up maybe 1/4", and it wss loud! It was crystal clear, and more than she will ever need on the loft. If anyone needs a amp for a bedroom setup, I highly recommend this as a great budget amp.
The amp is made of aluminum with a black anodized finish, 2 RCA jacks, and 2 bananna jacks. It even comes with the power supply. It is a little larger than a pack of cigarettes I believe.

I am using the 50wpc amps for my surrounds currently driving the Klipsch rp150ms currently, and they do a great job, but if I was to do it again... I would be driving them with the 100wpc amps. The 50wpc amps will be going into storage as soon as my new amp is built as that will give me balanced amps for 7 channels, and I already have 2 Yamaha p2500s 250wpc amps for my Atmos channels. Since my Yamahas, and new amp are all balanced amps I will keep them in service, but if I go beyond 11 channels I might very well run unbalanced and use these small amps.

These little class D amps are changing the audio landscape. Im looking at upgrading my motorcycle amp and the size of theses makes that a good option. How hot does it get when running for a few hrs?

The pricing is mind-blowing. Can you post a few pictures of yours (top, front, back, bottom)?

I hooked up a old pair of Advent Marbl speakers I had in storage to the amp, and I was hitting 108db from 18' away with the volume at 7 or 8 oclock.

I bet it would be perfect in blind A/B testing. I've got one in my closet that is similar, but it had issues when we tried it. Can't remember the name, but I'll look later and see.

Thanks for the info. I've been tinkering about making a HiFI Raspberry Pi just to try it out, and this amp might do the trick with it.
