HE-6 IMPRESSIONS IN THE HOUSE!
These things are freaking awesome sounding! I can't stop listening tonight.
My WA6 can now drive these to acceptable levels, while the prototype sounded way too soft at max volume. I'm listening to them with the volume at 2-3 o'clock, and while max volume with it isn't blasting or rocking it's louder than I want to listen right now in the middle of the night. I still prefer them more out of my SAC amp or EF5 amp as they still like a lot of power, but a speaker amp isn't mandatory now and a WA6 isn't out of the question anymore. I'm listening in my bedroom rig, and will try them on my ZDT in the basement rig later. My RSA Protector balanced portable is still underpowered with them, but I can now get normal listening volumes just before clipping occurs - previously it was a joke trying the prototype with any kind of portable. I have not tried any other portable amps, while my Protector is my most powerful one and the only one good with the HE-5 LE. The HE-5 LE are still more efficient than HE-6, and the HD800/HF-2/LCD-2/LA7000 even more so.
I'll give them my mandatory burn-in, and report back on the sound in a review, with a sneak peek now. So far out of the box they are very fast with good micro-detail, air ambience and space, with deep bass extension to 20Hz and up to the 16Khz limit of my 48 year old ears. They are fantastic with low volume late night listening, and I don't need to crank them up to hear the bass. Plus, timbre and tone are spot on and very transparent with pianos, unlike my LCD-2 which have pianos resonate in my ears. They're like listening to my high end custom IEM but with a full size phone soundstage. The soundstage is not as big as my HD800 but it's not small at all, and at least as big as my HD600 which are a little more intimate than my HD800 (some say the HD800 are too expansive, and artificially inflated, but I like it). I still greatly enjoy my re-cabled HD800, and I'm not willing to rank the two right now (too early). I need to spend some time playing with them, seeing how well they convey the big picture of the musical performances.
They now have memory foam inside the headband where it contacts your head, and with the softer leather they are more comfortable resting on the head. They're still going to feel big to people with small heads, same as the HE-5/5 LE, but at the smallest setting the fit is fine for me. My main issue with them is that like my old Edition 9 headphones they are fingerprint magnets. If you hold and adjust them by the arc and forks you can avoid getting fingerprints on them, but I found it was easier to just get them smudged right off the bat and not worry about it.
