Ok I see. If your Jot2/BF2 are new, maybe let them settle in and see if it opens up and improve. I noticed when new, the Jot2 was peaky bright and a bit muddled too at the same time. I now have about 115 hours of use on the Jot2 and a little less on the BF2 and not noticing these attributes, unless its a crappy recording. I use CD ripped 44.1khz wav format for my music by the way.I'm using all balanced in/outputs. I did compare to SE; balanced is definitely a step up (and it's especially recommended with the HEDDphone).
To be clear, I'm not saying the sound I'm getting from the Jot2/BF2 combo is bad in any way, far from it. I don't want to overstate the negatives. But here's my experience: I started with a pair of LCD-2's. I quite enjoyed them but they couldn't fully convince me because of similar issues: not enough separation, a bit muffled, not enough air -- even after EQ. So I went to the HEDDphone and it just blew me away on my little Element II. That amp clearly needed upgrading to get the most out of the headphones, so I settled on the balanced Jot2/BF2 combo. Now that I have it, it's a big improvement in a lot of ways (heft, control, dynamics, timbre) but when it comes to separation, air, etc, it's almost like I went back to the LCD-2. Well, a massively improved LCD-2, but still. For all of the improvements, there's also a marked regression in some aspects. And seeing as I really enjoyed the sound of the HEDDphone on a more revealing amp, I'm hoping to find the best of both worlds.
Hope the Jot2/BF2 improves for you as it did for me. At first I was not blown away, but I find it a very special combo now. Perhaps its both gear and brain burn in. But give it time before making a quick decision to buy or change things.
