Title: Audeze LCD-3 Sample 2
Post by: Marvey on February 16, 2012, 08:06:04 PM
LCD3 Waterfall Plot Comparison
My LCD3 pair was of the initial production batch. I don't know what going on with the ringing for LCD3 #2 at 3-4kHz, which I believe is a more current batch. The ringing is not in a fairly benign area. However it's a bit troubling.

This one I still consider "veiled"

At least the colors look pretty!  ???

What's more troubling is the bass response. These are uncompensated graphs that don't take into account the "seal." I would have to say the the latter production sample #2 sounded more correct the in bass - in other words, my pair sounded like they had too much energy in the bass.

(Black = LCD3 Sample #2, Green = my LCD3)

Note the odd resonances in the CSDs are hinted at in the FR graphs of LCD3 #2.

what's with the huge 20k spike? that must be killer on the ears with some stuff i would assume and be hearing an annoying type of ''sssssssssssss type ringing''. well hard to explain but i guess you know what i'm saying...i guess.

It's too high up for sibilance.  It's still kind of a mystery though because you'd think it might give them an airyness, but a lack of air is one of their biggest weaknesses.  I'm suspicious it's some kind of measurement artifact, but Tyll's graph shows it too so...

Three explanations:
But yeah, LCD2/3 have no air compared to most other headphones.

Wouldn't you think a 20k spike help with air?  What about the Take T BPP super tweeter (http://www.taket.jp/bpp/bpp_e.html)?   ;D

btw, Jude's review on Head-fi TV is pretty funny...

Three explanations:
  • People can't hear 20kHz. Anyone older than 11 years old who claims they can hear up there (at normal volumes) is full of shit. I most certainly can't.
  • The spike is a driver distortion artifact that doesn't bear any resemblance to the overtones of the actual music.
  • The spike is a measurement artifact and does not exist to the extent as measured.
But yeah, LCD2/3 have no air compared to most other headphones.

allllrighty then! i get it now. sucks to hear it has no air. i thought anything past around the 14k range would give some airness to the sound.

what the...what is that thing? how does it eve work? looks interesting but retarded at the same time.

Well, I think we are missing some perspective on the 20khz spike.  While the LCD3 is not the airiest, it is more so than the LCD2r.1 I think.  So it could be a deliberate attempt to increase air in an inherently closed sounding environment.  I might not be so quick to assume it's not supposed to be there.

You could always do a sinewave sweep and hear for yourself if you could hear that spike.

I know with the HE-400s, even though it has a huge upper-treble peak peaking around 14kHz with purrin's measurements, my ears tell me that there is a peak at 8kHz, and then another lesser peak at 12kHz, then a gradual roll-off, with sinewave sweeps and my ears.

There's too much variance in hearing sensitivity between individuals in the upper treble frequencies to really trust FR measurements there.

Past 12-13k, most human beings can't really make out much other than "air". Just not enough inner ear hair cell density.
