Hello monstertruck9882,
You've discovered the impressive world of modern class D amps. In my opinion, the least expensive method to attain true high-end sound quality. There are currently numerous very good quality class D amps available at very reasonable prices and it seems like the Appollon AS1200 is yet another fine example. Congratulations!
I use a pair of D-Sonic M3-600-M class D mono-block amps to drive a pair of Magnepan 3.7i speakers and I'm also very pleased with the results. From my experience having used 2 different class D stereo amps and now the monos, I've notice they all have had the same general sound quality characteristics as you describe with yours; a very low noise floor (I believe your hum is not normal), very low distortion, highly accurate, detailed, dynamic and overall a sound very much like the audio ideal of the amp being just a 'straight wire with gain'. In other words, the signal outputted is the same as the signal inputted, just with signal gain applied evenly across the audio spectrum that results in a very neutral overall presentation.
Enjoy,
Tim
