I own or have owned both Krell(currently 400cx) and Parasound (HCA 2200) amps. Parasound was my first entree in "the high end" and makes quality components, but what sets your requested/purchased KSA model into an entirely different category is the manner in which the power supply is implemented in Krell amps. These amps have huge power supplies and they are not current limited the same way that Parasound products are and, as a result, and in my experience, deliver bass and dynamics, both micro and macro, that are very powerful and true, simply because bass frequencies require stiff current capability to adequately drive the woofer motor. No woofer "tells" a Krell amp what to do, it is quite the other way around. I also feel the build quality of Krell amps are a couple of steps higher than Parasound, albeit you pay extra for these differences, but in my opinion they are worth it and I have been enjoying the 400cx going on 9 years without any problems (knock on wood ;-) Steve
