Just because he hasn't posted about the Asgard doesn't mean he hasn't owned it. I too would find it a bit strange, but to blow him up about it isn't fair to anyone, especially the OP, who's thread you just crapped on.
Perhaps asking him, instead, why, if he's owned an Asgard, hasn't he posted about it would have been a more polite way to ascertain the facts.
on topic:
I've owned the LD MKIII (Yikes you going to check me on this?) with the HD600 and found the sound good, but I could tell there was more to be had. For the money it's a great amp that will give you most of the HD600's sound, certainly a much more filling sound than without a dedicated amp.
I haven't owned an Asgard, mostly because I've time and time again demonstrated that I prefer tube amps in almost every situation. I'm sure it's a great value, but I just don't get the feeling of the music nearly as well. The Asgard does have a trial period so you can't lose if you like it right out of the box if you order it first instead of the MKIII.
Service from both companies appears top notch. I've dealt with David at Little Dot a few times in emails and it's always a courteous and honest exchange. He never uses form letters in my conversations, so his reply is right on topic and always answers my question right away.
From the posting I've seen in the Asgard thread, Schitt's service appears to be just as excellent. I think someone had a DoA Asgard and it was fixed and back in the owners hands in less than a week. That's great stuff.
