Ok, gotcha. The DS amp is very good, but the quality doesn't match the Mjolnir. The DS amp is more neutral than the somewhat forward Mjolnir sound--which I like, but the soundstage is smaller. I find that a lot of mid-priced amps have a limited soundstage and can lack resolution and dynamics to some degree. The DS amp generally holds it's own with respect to resolution and dynamics, but falls short in terms of soundstage when compared to top-tier amps.
