Got a chance to try the DT-880 600 ohm with the Schiit Asgard today.
It seems to do well with them. It's not a perfect match though and I probably wouldn't suggest it to someone was actually wanting to get a cheap amp specifically for the DT-880 600 ohm. It will do the job though and quite well.
On some music, you max out the volume and it gets to just under ear splitting volume levels (yeah, I know volume doesn't mean anything really).
With most music I max out the volume. On some classical the volume is a bit lower then i'd like. What's strange is that when I skip tracks and it goes to some pop music the volume has to be turned down. I guess this is just how they are mastered.
On the HD-600 I only put the volume at around the 1 o' clock. Maxing it is around 5:30 on my asgard.
These headphones sound a lot better and different then I expected. So far mine seem fairly neutral. Nothing is jumping out and annoying me. There seems to be a bit more bass then I was expecting, which is a huge bonus.
The treble on some Beyer headphones can annoy me, but so far it's not bad at all.
Vocals are good so far, this is the area where i'm really picky. These seem to be VERY revealing of any vocal sibilance in my music. It doesn't add it since it's already in there. It's a lot less noticable on other headphones, like my HD-600, but it's still there.
Luckily no recessed mids from what I can tell so far.
Don't know if i'll keep them yet, but probably. Really it's just amazing how many recordings have so much sibilance in them. I keep hearing sssshhhh and ssssss a lot. I verified it before in other headphones and it definitely is there on each headphone, but the most annoying on the DT-880 600ohm.
BTW I haven't burned these in yet and this is all just a few quick comments on how well the Asgard drives these.
UPDATE:
Strangely the Asgard actually drives the k601 better then the DT-880 600. Someone told me yesterday that the k601 is actually harder to drive then the k701! With the k601 the volume stays at about the 2 O' clock position.
I'm liking the k601 a bit more, but I need to compare them more side by side. The k601 clearly has better vocals, but does lack in bass a bit. It's not too bad though.
