1- The packaging could have been a lot better. The block is not sealed, is it new? Is this a return? 2- No manual, no warranty card or registration website, how long is the warranty period? 3- There should be a link to the power adapter on the product page so that both items can be ordered at the same time. 4- Good thing, it sounds pretty good for such a small device. I just hooked up a pair of 6 ohm 100 watt Sony SS-CS5s, so I moved the amp to power a pair of Polk Monitor 50 8 ohms. 150 watts and this little amp drove them to room filling volume, at max it hit 83db and filled a living room 21x19, the bass and treble controls worked well and there was only background noise when the volume was full with no music. I haven't hooked up a subwoofer yet, I'll check that later, but with the Polk I didn't feel the need to have one. that's a decent run, wow!
