Finally got a pair of these babies, which I have lusted after since they debuted as a China-only product last year. Thanks to fellow Head-fier
@dougq for a smokin' deal and superb, smooth transaction.
First impressions: The Edition XS fulfill the hype -- and then some. I'm beyond delighted with these after the first two hours of listening.
I'm happy to compare these to a few headphones outside of the HiFiMan line -- I've owned/own HD 560s, HD 6XX, Elegia, Meze 99 Classics, ATH-M40x, ATH-M50x -- I think it's probably best and most accurate to compare to the HiFiMan headphone that I own, the HE-400se.
I know the Sundara is the step just below the XS in the HiFiMan, but I've never owned or tried it. Decided to jump straight from HE-400se to XS after my recent purchase of the Elegia showed me how mid-fi can be a considerable jump over entry-fi.
The Edition XS basically take what's good in the HE-400se and elevate it about five times. And it takes the flaws of the 400se and fixes them.
All of these impressions are without EQ. I'm not a huge EQ guy, as I like the varying sound signatures of the cans in my collection (HE-400se, Elegia, HD 6XX).
First, the Edition XS bass. It's more controlled, punchy and present than in the HE-400se, which already has good, entry-level planar bass. There's no grain, spike or congestion in the treble so far, which can be a problem in some complex passages with the HE-400se. But the biggest difference in the basic sound signature between the HE-400se and the Edition XS are the mids -- they're far more defined and present in the Edition XS than in the HE-400se.
Other thoughts about the XS compared to the HE-400se ... Clarity? Better. Imaging? MUCH better. Soundstage? Considerably wider. Comfort. The same -- both are very comfortable, but the XS has even less clamping force. Good for my fat, bald dome.
I'm not an audiophile with decades of experience and a fat checkbook. I've been active in this wonderful hobby and with its cool people for about five years, and my finances finally have allowed me to graduate from entry-fi to mid-fi. But the Edition XS are the highest-quality all-arounders I've heard. The only headphone I've heard that's better is the Focal Stellia, and that's a $3,000 can.
There's just nothing in the XS' sound signature that offends my ears and brain in the slightest, which is rare since I'm very treble-sensitive and suffer from raging tinnitus. And there's a HELL of a lot in the sound signature that matches my idea of audio nirvana.
Time to compare the Edition XS to the other mid-fi can in my collection, the Elegia. Yes, the detail and some of the treble in the Elegia match or possibly exceed that in the XS. But the Elegia don't do bass or soundstage nearly as well as the XS. The Elegia are great for strings, classical, vocals, acoustic, piano jazz, bluegrass -- music that lives in the mids. But they're not so great for rock, alternative rock or metal.
So far, the Edition XS have been great with every genre, just like my HE-400se, which are THE definitive entry-level can, in my opinion. But the Edition XS are just significantly better at everything than the HE-400se.
Finally, I don't get the fuss about power requirements for the Edition XS. I'm driving them to ample volume on low gain of my JDS Atom+ stack. The dial is at about noon or 1 p.m. I'm sure more powerful amps would elicit even more fidelity, but I'm already in rapture at what I'm hearing.
The Edition XS may stop my headphone churn for a while. They're THAT good. I feel like I would need to pierce the four-figure spend range to get anything much better.
I'm so damn impressed -- and happy!
Feel free to toss any questions my way.
