Haven't heard the 598, but I can tell you the HD600 is the not the ideal headphone for those genres. The HD600 doesn't do very well with music that has too much compression, like metal, newer rock and pop.

First piece of advice is stop equating cost to sound quality. They do not go hand in hand, especially in the under $300 range.

I can't listen to my 580 with the 580 grills. Sounds congested and muddy in the mid-bass after using the 600 grills for a couple years.   Quote:

Just returned an A2 and picked up an M/M after reading your review. My combo came with some real flexible PYST cables. Looks to be a thinner cable than yours. I didn't do a direct comparison, but the A2 was more spacious sounding, but more laid back in the highs. The M/M was just what I was...

In my experience with the 225, I didn't find amping changed the sound a whole lot. The 225 is not known for low end. When I had mine, I just flipped the bowls around so the flat part of the pad was on my ears and it gave a nice 2-3db boost in the lows.

I just sent an Asgard 2 back. I was using it with my HD580 (600 equivalent) and it was a great amp except the treble region. The A2 smoothed out the treble and took the bite off of it. It was the first time my 580 sounded kind of boring. The bass, mids and soundstage were great though.

Now that I have had some time with my A2, I'm just not feelin' the mids. They lack detail and are pretty laid back and this is with mid-centric headphones. I couldn't imagine listening to Beyers with this amp. Just not my cup of tea. Too bad because the bass, highs, separation and soundstage are...

Maybe everyone can copy and paste their reviews / impressions into the Asgard 2 thread. It just doesn't make much sense to have them here.

Hey guys, don't you think reviews and impressions would be better served in the Asgard 2 thread versus this announcement thread? This thread is going to make it harder for those in the future to find info on this amp as most people will be looking in the full size amplifier forum. Just a thought.

Straight from Schiit.com   Additional Versatility: From IEMs to Orthos to Active Monitors Asgard 2 offers two gain settings. The low-gain mode is perfect for high-sensitivity IEMs, while the high-gain mode is ideal for most other headphones, up to and including many orthodynamics.   I...

Silent. In case anyone is wondering. 125 degrees inside the case. 110 on the case top. Volume knob is 116 degrees. Wear your silicon mittens while adjusting the volume.

Not a great pic, but you get the idea of the size. Sounding pretty good so far. Not sure how I feel about the bass yet. It's fast, yet full, but rounded if that makes sense. Maybe a hair laid back in the mids. Soundstage is nice! This is all in comparison to my DIY tube hybrid amp. Going to let...

Nice, mine will be here Monday. So how does it sound? Expecting a full review in the next 30 min! 

DT250/250 is a closed HD600.
