A lot of people who own and use the Asgard 2 will disagree with you as to your claims of that amp. As far as quality power, 100 mW cannot drive an HE-500 past a 109 dB peak without gobs of distortion, that is certainly not quality. That Little Dot MKII at 100 mW at 32 Ohms is not going to be able deliver on an HE-500 no matter how much you or HiFi (yes you gave it a +1) wish it to. That amp is designed for and works for higher impedance cans. How you can make this claim, makes no sense to me. If pairing this pleases you and that's what you want, go for it. I'll pass on this choice. If on the other hand you desire a boutique amp, that's cool. The Asgard 2 is not one of those cheap amps you try to make some odd point about. You might try using an A/B switch to do proper comparisons, it can be an enlightening experience.
