Sorry for the late response. After reading this whole thread, I noticed that a few folks seem to find that the Burson Conductor to be a good pairing with the Empyreans, but I'll leave that to actual owners can obviously chime in with their more informed thoughts. I definitely endorse the Topping DX7 Pro as a budget pick, but take my input with a healthy bit of salt, as I'm wet behind the ears with gear and have not tried any other options. That said, I hear what I hear, and from my standpoint, the DX7 Pro has been very good for me, definitely no lack of clean power.
If anything though, the DX7 Pro's reputation to be more on the analytical side is certainly true for me, and I personally find that with my chain, the leather pads in particular can be a bit on the harsh/bright side with a some of my music, although YMMV. As such, I do think it's possible that an upgrade to something perhaps a bit on the warmer side while still being plenty detailed (like the Conductor) might be exactly what I'm looking for in general, although I'm not going to upgrade at all without an audition and finding something I find to be worth it, as the Topping DX7 Pro is pretty solid.
Thank you so much for this review, it's a great read and extremely helpful to the rest of us. I find that your comparison to (perhaps more well regarded) TOTL choices that you own is very interesting. I would think that given your gear, it'd be really hard not to either A) be completely biased based towards the great headphones that you already own and are used to or B) get overly excited about something because it's new and fresh. Well done!
I totally agree with you about the differences between the leather and Alcantara pads, even though your chain is superior than mine, and we listen to totally different music.
Again, to sum it up the most general, simple terms, for me, with my present equipment, the leather pads are high reward/high risk, and are best suited for slower and less complex music (again, being very general here). The Alcantaras being the more solid choice really shocks me. If the Alcantaras still sounded like they did when my Empys were brand new- I would have been totally disappointed overall, and that's fascinating to me. My biggest question, how much of it is equipment breaking in versus my brain getting used to the Empys?
Honestly, it doesn't really matter, because perception is everything, and I'm really happy. I'm sure that there are other headphones that are purely better at detail retrieval, but I'm honestly not too hung up on that, I find that the Empys offer microdetails in a way that I find that to be natural and enjoyable. I hear chairs move around in song that I haven't heard before and can almost visualize the positions of the chairs, just more details in everything, seemingly (with Alcantara pads). I've listened to Violent Femmes "Add It Up" dozens of times over the years, and tonight was the first time that I SAW Gordon Gaino smirk when singing a certain line. Very cool. The resolution and overall sound makes me not want to listen to my Elexes, period, no offense to anyone who also owns and likes the Elex (and they're a heck of a lot less money).
Headphones are one of the most subjective hobbies that I've been around (besides visual art and music itself), but there are definitely key distinct similarities with other hobbies I've enjoyed.
Depending on the hobby, I find that often, buying better quality/flagship gear is not assured to work better for everyone. Why? Higher quality gear is typically designed by opinionated enthusiasts with their own specific tastes in mind, just something to be aware of.
