Yeah, planar can always make the midrange more detail and clarity
JCX - That's an interesting theory.
White Lotus - That would be my best guess. On the other hand, we are having a real headphone renaissance these days, as head-fi has been identified as a good niche for a lot of companies. Must be the success of Smart Phones or something. I would point out that a lot of flagships have what, 10 year runs? The HD 600/650 have been around forever. Seems only recently Sennheiser felt the pressure to really do something new and awesome.
MikeAJ - while I don't agree with "midrange weirdness and distortion" in the HE-400 (which I think have a beautiful midrange at times), the distortion has been measured. I would point out that said distortion is recorded at pretty high SPLs, so we don't always know how speakers are behaving at less ear-damaging volumes.
Double-ended planars are supposed to do better with respect to distortion than single ended, as two magnets provide twice the control of one. But they also would impact the diffusion of sound, I would think, so single ended probably has even better intimacy in exchange for more distortion and less linearity at higher SPLs.
I have to admit, the HE-400i seem to me, at least initially, to be a weight / cost / performance cut at a higher price - the opposite of what a consumer wants. But I guess the Magnepan speakers are single-ended also, so, you don't know til you can hear.
Could you tell more details about HE400i?
My Mad Dogs have more precision in the sound, especially in the sub-mid bass region. This is clear on acoustics tracks.
The problem I hear is present in piano music. It loses a lot of the dynamics that the artist intended (it's obvious because some scores have accents to them, and the Mad Dog do not portray them well). Everything seems "flattened" out to the same dynamic level. At first, I thought this was because the Mad Dogs were so neutral, and they are, not particularly emphasizing any particular frequency except the bass (to compensate for the vibrations that enter our bodies). But even with this in consideration, I feel like I'm hearing a wall of sound. I need to hear another planar magnetic can to confirm if this is just that kind of signature. MIdrange has less presence in my Mad Dogs for the most part, with a more artificial timbre.
Oh yes it's definitely fast. The problem here has nothing to do with fastness. And no this applies to every song/ piece I've listened to out of the Mad Dogs. I've been trying to find comments about this 'wall of sound'. I've read it once somewhere but can't find that specific comment. Instead I've found:
"As Brooko said, I didn't say inferior.
The "deal" with any planar radiator (ESP, electret, planar-magnetic/orthodynamic, etc) is that they put out a very uniform "wall" of sound, compared to the conical pattern that will come out of a dynamic cone (which is what you'll find in every Grado ever made). This is a very different presentation on it's own, even if they had the exact same frequency response (which they do not), because of how the sound-wave will interact with your outer and inner ear. So just like how an Ultrasone with S-LOGIC will not image or position audio in the same way as any conventional headphone, neither will any planar radiator. Same thing with speakers - there are plenty of great-sounding speakers that use multiple drivers in various alignments, and there are also a number of planar/dipole models that are also great-sounding. But they produce a very different sonic image because of the difference in how they put sound out.
So not only should you expect to see a large difference in tonal balance (in that, nothing has the same PRaT, tonal balance, etc that a Grado does), but the difference in radiation will also change and influence the sound very heavily. I will tell you that flat-out, if you think your Grado headphones are the best sounding thing since sliced bread, nothing else will get you that same experience except another Grado. They're very unique. I say this to hopefully prevent a lot of dragon chasing - don't waste your time with other manufacturers trying to get "a better sounding Grado" - just get a better Grado. If there's *major* issues you have with Grado headphones (e.g. you hate their tonal balance), don't waste your time buying more expensive Grado models - try something else.
It all ultimately comes down to preference - do you like chocolate or vanilla or perhaps Neapolitan?"
"The "wall-of-sound" effect is because LCD2s are heavily damped, unfortunately that damping scheme is also what makes it sound like an Audeze headphone. I can make my HE400s sound quite LCD2-like with similar driver-back damping with foam and felt, without the properly tuned bass response / smooth mids ofc, but as a proof of concept."
Wish I had another planar magnetic to know for sure. I've only ever listened to dynamic drive headphones (lots of them) and they don't have this kind of sound.
No not at all. The HD650 does sound heavy, mainly because of its midbass. I had the same impression with the M50s as well. The Mad Dog has a very neutral midbass... about the same amount as my HD598 actually.
Maybe one day when I get the chance, I'll be able to compare it with a HE-400 or another planar magnetic.
Oh and I didn't "upgrade" from anything. I own the HD598 currently, though I've auditioned numerous cans in the price range and above. No dynamic headphones sound quite like the Mad Dogs. My main interest currently with the Mad Dogs isn't really its "wall of sound" but rather the lack of dynamics. Everything feels dampened, and although this doesn't affect most genres of music, it does affect my piano music heavily. A friend came over to audition my two cans and he agreed that the Mad Dogs just can't compete with the HD598 in classical music (well excluding organ). But he loved the Mad Dogs for darker ambient music.
From what I've read so far, dynamic and planar magnetic are two different technologies.
Went through the article on innerfidelity by Tyll.
My observations so far:
-- Planars seem to be the 'better' design. Better from a purely electrical and sonic standpoint.
-- They're heavy and may be uncomfortable.
-- They produce a planar wavefront. The same is done by the HD800.
-- Planars seem to struggle in the high frequency area.
Questions:
-- Why aren't they popular? Disruptive Technology? Price?
-- Why can't other dynamic headphones be designed to produce a better wavefront? The HD800 seems like it can.
-- Are they 'superior' or just 'different' ?
When one passes a signal through a filter (or a headphone), the "processed" signal will not come out immediately. The signal will come out a bit later because hardware does not respond instantaneously to an stimulus. A bunch of junk will come out first depending on how "fast" the hardware is, and how it reacts to certain frequency stimulus. This junk that comes out first is usually referred to as a transient.
AFAIK, the impulse response represents the linear transient behavior of filter (or a headphone). I guess the less junk before and after the main peak of a headphone's impulse response, the "faster" the headphone.
