Hey guys, thought I would give you an update.
The Asgard 2 amp has really amazing, and as far as I'm concerned, a requirement for my HE-400's. I don't see how people could keep these on the low impedance setting - they just come alive with some juice. I pretty much love all of my music on them. It has pretty good base - even more would be OK with me, but I'm happy.
I received my Mad Dogs today. I had them plugged directly into my MacBook Pro today at work - and brought them home to play on my amp this evening. I gotta say, they just made me miss my HE 400s. They are much more comfortable - but, they're just kinda boring. From what I've read, it may just not be exciting enough for me because I haven't developed my ear as of yet. If I liked it, I was thinking upgrading to the alpha dogs, but at this point, I think I'm going to return them.
The main problem I'm having is that I can't really crank them when my Wife is in the room - and I just like to crank them. :)
So, I'm still looking for some closed cans. I would probably pay 600 for a great pair of them. In fact, if I could get a close pair that sound as good or better than my HE 400s I'd just trade them in and have only one pair. I'm not looking to have a bunch - just one pair that I use for everything.
I'm going to a meetup this weekend near DC and am looking forward to listening to what everyone else has.
I guess my other thought would be to get some in-ear instead of over the ear. Still have to do more research on that.
Peace ya'll. Thanks again for your advice. I still need to rip some CDs to listen at the better quality - just been spotifying up until now. Maybe I'll do a few before bed.
