Audeze LCD-2 Orthos - Page 14

Thanks for that explanation Kevin. Something that comes from years of studying and implementing headphone/earphone design obviously

I just read through some of the Fletcher–Munson curve stuff and its graph for the same perceived hearing level is similar to this frequency response at 90ish db except for the higher freqs(8k+) started going back up.

Do you find it lacking any oomph in that area, like splashing hi hats and certain cymbal hits? I'm soo used to my k1000 that its hard to listen to phones without the far upper register anymore. Sorry to keep asking questions but I'm interested and want to make sure I won't be disappointed if I drop more money on headphones. Thanks for all the explanations btw.

I also noticed while tuning my t20 over and over again that the far high and low end was a trade off with damping. I'm wondering if its just a trade-off that has to be made due to the driver size/type. aka a lesser of 2 evils type thing.

Meh! I hope not, that's the old headband.

Oh well, I'll go full custom then.

Not at all. The LCD-2s have NO lack of HF response at all. The Fletcher-Munsen loudness profiles have NOTHING to do with the subject of how our pinnae affect the sound we perceive. They are two entirely different subjects. Loudness contouring is yet another area where a good headphone designer's experience comes into play. To FM contour or not to contour??? That is the question! Actually, I prefer to leave that department mainly to the amplifier, since loudness contours are usually addressed there anyway and are designed to track with overall loudness levels as they should, rather than being a static thing.

Here's a good introduction to the head related transfer function and how we hear;

The headband has been redesigned. The earcups have mount points for the mini xlr's. If Audeze do not post pics soon I may post some.

I wonder if Audeze is planning an upgrade program for LCD-1 owners..

High and low end response is not exclusively nor inexorably linked with damping, electrical or acoustic.

There are many, many factors that come into play when tuning/contouring a headphone's response. Everything from the proximity of the driver to the ear, type of seal around the ear, volume and permeability of cavity behind the driver, and yes, the damping in front of, and behind the driver. Then there is the electrical damping, strength of magnetic or electrostatic field, resonant frequency and Q of the driver, on and on...

I just got back home and all these demands for pictures ?

Ok ok , peer pressure , a pic

I don't know if any of you have been following Tyll's adventures in measuring headphone performance, but it is quite an eyeopener to see the real life response curves of some of our finer headphones. The HD800 in particular where initially a little unrealistic but then as kw points out. Our ears and brain act not unlike a filter, there are some very good articles on this and the psychoacoustic perceptions if you search pubmed.

On a side note, I discovered this past week that Ia guy that has been traveling the same bus route as me for the past few years was a magnapan repair engineer - 'my hero'

I am using an amp which I hope some of you get to experience at some point. It is a direct coupled high voltage tube hybrid, class A mosfet with plenty of power and swing. It is faster than the B22 on sims and has no trouble driving any of my planars ( even the infamous wharfedales. ) My initial test for the LCD2 was if it held any substance to the wharfedales which are truly world class. Again, very few of you have heard my modded wharfedales and I have held off posting about them as Saachi was trying to acquire a pair cheaply. The truth is, they wipe the floor of any ortho to date , they go to 20 Hz and are smooth through the bass, mids and highs. No funny peaks, or dips, just 'pure dead brilliant' . I have not done a comparison as yet but the LCD2 is the first ortho not to make me feel immediately that it was no match for the wd's. They do not have as much bass presence but they are very close and keep the low timbre and detail without the typical bass hump which intrudes on the rest of the music. I think these will be a bass heads dream as it reproduces those low notes accurately and with detail that will leave the D5000's jaw hanging. KW has had more time with them and I will leave further impressions and detailed discussions about my impressions for a later time.

Ooh, I want to meet this guy! I'm from White Bear Lake you know, where the Maggies are made.

aww man..you didn't hold off long enough..that's just going to drive the wharfie prices crazy now . Curse myself for selling my wharfies earlier in the year And by very few you mean other than you, just me who's heard it

Don, detailed pics and descriptions of your wharfey madness. I said I wasn't gonna mod mine... but now I might.

Heheh
