I've been listening the Empyrean for few hours at couple of nights. I haven't tried other cables yet, I just plugged in the silver plated upgrade cable from Meze and concentrated on the pad choice. The leather pads came preinstalled so I went for them first but felt that with the silver cable, the sound is a bit too aggressive for my liking and I quickly tried the alcantaras and found that they were perfect match for my tastes. It is lively, really life like presentantion and while people seem to complain the lack of technicalities, I really don't hear it, the sound is really dynamic, the sub bass is really good, treble extension and clarity is spot on to my tastes, so are the middle frequencies. So far, so good. The detail retrieval is also on par with the previous headphones I had (Stellia, Rögnir) so can't complain that either.
So far, these are 5/5 for me, especially with the silver cable and alcantara pads. I get a bit pulled back from the presentation of the music but this allows me to concentrate on the whole, not as much on different details that make the whole, if you guys know what I mean. The cohesive whole let's the details come out naturally and I really how they are presented.
