Musical Fidelity KW500 and Rowland Continuum S2

I have the JR 525, but it's my understanding that the S2 is a step or two above the 525.

Arsh,

I can't compare the JR 525 to Musical Fidelity, because I've never listen to MF. In the context of my system the JR 525 is very musical. I never thought changing from an Parasound A21 to the 525 would yield some many improvements...the most impactful is spacing between instruments.
Again, in my system the highs are musical,real,great tonality and the mids are better. The bass compared to the A21 is very different...A21 more impact, 525 tight and detailed.

Arsh,

I have owned and/or listened to several Class D, A, and AB amplifiers. I recently had an Jeff Rowland 125 for two weeks and now a JR 525. Based on my experience JR Class D amplifiers don't sound like "Class D" amplifiers. To my ears both JR amps that I've listen to in my system portray a three dimensional soundstage where music emerges out of a black background.
