Here are my first impressions with the Schiit Asgard 2 amp, that I received last night, with Grados... (copied from the Schiit thread)
My first hour of listening was straight out of the box, coming from a Bifrost (USB, non-uber), to the RS1i. At first listen, I wasn't too overwhelmed... wasn't quite what I remembered hearing, but memory can be a capricious beast. But over the course of the next hour, I can say the bass is deep and well-defined, but not heavy. This amp is not as bright as I anticipated (especially with the common thought that they don't go well with Grados), and actually I don't really think I'd call it any more bright than the headphones that you plug into them - by definition, I guess I'd call it transparent. I'll plug in my Q701s later, and that should really show if they just emphasize a bright headphone's brightness or not. The PS500 immediately feels more at home with this amp. To my ears, there's less adjustment my brain needs to make listening to the PS500 than the RS1. It could just be the more bassy nature of the PS.
The soundstage of the Asgard 2 is impressive. Grados are not known for their soundstage by any means, but it certainly feels wider and deeper than either the Fiio E09K or the LD1+. Speaking of the E09K, I think I'd call the signatures between the A2 and it similar, the Asgard is just cleaner and more articulate in every way.
The build quality is really, really impressive considering the $250 price tag. Schiit builds good gear - no doubt about that. The volume pot is smooth, with just the right amount of resistance to me. It's a hefty amp, and feels very solid... very sharp edges, though. I may take a small file to the edges to bevel them a bit.
Now, to compare to the LD1+, the A2 is brighter - I'd like to say it's less cozy - than the Little Dot with Voshkods, but that's not necessarily a bad thing. Just depends on your taste. As I mentioned before, the main reason I wanted to try this amp alongside the LD1+ is the inherent low-maintenance nature of solid-state. The tubes I have in the LD are very susceptible to RF, and that can put a damper on a good listening session if my tablet or phone are anywhere near the amp.
In the end, I have space for two amps on my listening table. Like having multiple headphones, there's a toy for any occasion. It's a really good amp for $250, for sure!
