I couldn't find a thread, so I thought I'd create one, mods pls move if I've missed it. Stax's new flagship. I've been listening for about 4 days so far. These are legit, but I'll report back with longer thoughts once I've done my full review. Short impressions Overall I'm very impressed. Based off of others impressions, I thought that in terms of overall character they might be a laid back warmer listen, but they aren't coming across as that, at all really. I don't really feel like they are an improved 007, or an improved 009(S.) They are doing their own thing. More treble than I was expecting, or maybe it's just a spike somewhere in the treble rather than an overall elevation of the highs. They are the "biggest" sounding stax I've heard but not as big as the Shangri-La Sr sounds. When I say "big" I mean in terms of the overall sound, not necessarily soundstage width etc. Its hard to explain, but to me there is a difference between soundstage, and how "big" the overall sonic picture is. Soundstage width is wider than the SR007 and SR009. Imaging seems to be a very strong point for these. The space between instruments within the soundstage is very impressive, and there is real depth going on. Also they are most detailed stax I've heard, but they seem to lack the last 5% of micro detail and "delicate" sound the Shangri-La Sr have. I have not heard the original omega from Stax so can't comment there. Also, Positive - The bass. Honestly surprising. I'm running a modest low shelve from 100hz on down as I do with most headphones to some degree, and the bass is very satisfying. It takes the light low shelve like a champ, no distortion, or other problems. Could happily live with this bass and I'm not a fan of the 009's bass at all really. Even if you boost it there is just no slam or impact at all. The negative? 3khz. There was something I couldn't put my finger on. It wasn't "brightness" in an overall sense from the treble. It was just anything above a medium volume level, especially with vocal stuff, was annoying the heck out of me and ultimately ruining the listening experience. Doing a 3.5db reduction at 3khz fixed it entirely and now they are very much in my favourite headphones group for their overall experience. I know some people will blame it on my cables, or my amp (though I'll hopefully have my new amp by august but I digress,) or DAC, or whatever. I've never experienced anything like that making enough of a difference at a specific frequency to fix something to that extent, but hey maybe they would be right. Its 3khz peak isn't as bad as the CRBN, and when I say "bad" I mean for me personally. Some people love the CRBNs stock tuning, and it is even more forward than the X9000, so YMMV. Build quality impresses, and the leather for the earpads is probably the nicest I've felt thus far.
