My HE-400s arrived earlier this evening and it sure does feel good to add them back to my collection. The memories of getting my first pair came flooding back as soon as I hooked them up and hit play. The shock of going from the Ultrasone Pro 900s to the HE-400s is incredible. They sound so different (not necessarily better or worse and, if I'm being honest, they sounded pretty bad during that stage of readjustment). Thankfully, it didn't take long at all to get right back into them and remember exactly what I loved about them before. They're a great set of headphones. :) The Pro 900s are excellent, too, but it is nice to have something with a different flavor.
It was weird because I had the same reaction when I was caught off guard by the seemingly weak bass. It's exactly what I went through on my first pair. I can't remember if I had done something wrong, if they were faulty, or if I just had to adjust to the different bass quality/quantity. All I know is that, after a short amount of time, I was thoroughly impressed by the HE-400's bass performance. I'm going to stay away from the Pro 900s for a while so I can get fully indulge in these new babies. They sound so freaking nice as they are and I haven't even swapped the pads to the velours that were included, done the grill mod, or set up any EQ in JRiver Media Center.
Edit: I just installed JRiver Media Center on my desktop (I forgot that I never reinstalled it after reinstalling Windows 8.1 when I set up my RAID0 for the boot drive) and imported my music. After a couple of strategic cuts in the EQ, the HE-400s are back on top and rocking my socks off. My goodness, they're phenomenal! I listened to Beck's Morning three or four times and loved every second of it. I want to be listening to them right now but I've got to pretend to go to bed so I can get up for work in the morning.
I did some quick comparisons before I put them away for the night between the Schiit Magni and the FiiO E09K with the Modi as the DAC and I was surprised at how much I prefer the Magni. I love the E09K on my Pro 900s but the Magni seems to play nicer with the HE-400s. I did this before installing JRiver and adjusting the EQ, though. Either way, I'm really starting to like the Schiit stack and I love how responsive the HE-400s are to EQ tweaks. What a great combo!
