LCD3 Measurements - Page 4

post #46 of 236

I actually had an audiogram performed...about 18.5kHz in both ears. Not bad for pushing 40. tongue.gif

I could use more boost at 16kHz. Done with LCD3.

Well, according to that I can hear 19khz and 5, 10hz better than 20hz......eek.gif.  Those results in the lowend are actually similar to an online audiogram I've taken a few times though the treble on this tone generator was more generous than the audiogram which I think capped me around 16.5-17khz.

Guys I am pretty sure those online tests are fairly inaccurate.

I didn't take it myself.very_evil_smiley.gif   I don't even let my doctor give me one.  My last checkup he asked me if I wanted to test my hearing I said "What?"  He said Would you like your hearing tested I said "what?"  He said would like your "what?"very_evil_smiley.gif  I grabbed some Viagra instead.

They probably have a secret lab facility with engineers who have been doing these kinds of measurements (and even more) for some time now.


Dood, they do strobed laser interferometry to watch cone break-up real time.  

 

I too am AMAZED sometimes at the level of technical performance of the HD 800. AMAZED!

Tyll when can we expect to see your review of the LCD-3? I am sure you pre-ordered it, and should have one by now right? biggrin.gif

My problem with those listening tests is you’re at the mercy of the transducer and chain. One rig boosts the highs and you think you have great hearing at the higher frequencies, others attenuate them and you’re bemoaning your old ears. I’d need to be sure of the quality and neutrality of the listening gear before taking any test as a serious indicator of my hearing.

 

Anyway, I just wanted to say that I really like the new trend for objective measurements in the headphone hi-fi community. Between the fruits of Inner Fidelity, NwAVguy and Purrin here at Head-Fi, people who have always sought this stuff out have been somewhat spoiled recently. Great stuff and thanks to all contributing towards this body of research.

If they can work such wonders on crappy dynamicals, I an only imagine what they could do with an orthodynamic driver and their secret underground lab with strobed laser interferometry and associated gear.  I'm picturing a place like the Darma Initiative labs.  Maybe they use old Nazi facilities.

Too bad they produce too much sibilance on female vocals, and their bass is on the anemic side.
 

In my experience, it's pretty easy to find speakers which sound great all-around, and there are many choices that fall into the category where it's hard to point to any significant weakness. With headphones, you can always point to some weakness, which is I guess why people keep trying different ones in an endless cycle...

There is a chance that this problem will be solved with an upcoming new headphone technology. The problem is that all drivers (even the new LOTUS from audeze) have resonance in the highs or midrange. Ribbon heapdhones can have driver resonance at 5hz for instance, instead.

Well, if you aren't going to commit to extracting the best out the HD800 you aren't going to be rewarded, quirk of the phone.  Also sounds like you might have heard an earlier production unit or just had poor synergy.  Regardless, the 800's issues are more easily fixed than most others.

 

Funny I recall your comment about the 009 bass being all that.  I've heard it now w/ 4 different stat amps (323/BHSE/KGSS/Electra) and the word anemic is far more appropriate to the 009 than the 800.  I think that was a pretty solid consensus at our last meet when AB'd side by side.  The only way to explain that away would be to say the 800 had colored bass.  blink.gifwink.gif

That's why I ended up holding on to the HD800 and built a setup around it to minimize its shortcomings and maximize its potential. It wasn't cheap. I still maintain that a properly set up (and Anax modded) HD800 is better than the LCD3. The orthos sound compressed and just don't have the dynamic capability, and that aspect is #1 or #2 on my list.

So very true.

Graph of the Titans

Zoom In Overhead Comparisons

  • Floor moved down to -39db (it's usually -30 for most of my graphs.) This makes things extremely revealing - as we will see with comparisons with other headphones. Note the Audeze provided CSDs only go down -25db.
  • Frequency range is 1000kHz to 22kHz. Let's us concentrate on the most critical portion of the audio band for this type of measurement.
  • Short focus timeframe from 0ms to 3ms.

 

LCD3, SR009, and HD800 (anax mod) below:

lcd3 r.txt.jpg SR009 r.txt.jpg HD800-4.txt.jpg

 

SR009 has the cleanest treble. There is a little bit of hash on the SR009 which is typical of STAX. The LCD3 is no slouch and wins in the upper mids. HD800 has some residual energy in the upper mids, but it is the most open sounding with the least amount of interaction with the enclosure (lower left quadrant - past 1ms and below 3kHz). All three are very good, especially compared to some other TOTL headphones.
