Note_1: My first impressions of the sound of the LCD2 (Fazor edition) headphone are based on direct comparisons to other headphones - the AKG K812 and K712, the Beyerdynamic T90, DT1350 and T51p, the FAD Pandora IV and VI, and notes I've accumulated from many prior reviews. I describe how I relate to the LCD2 (i.e. my personal tastes and how I use the headphone) only after covering all of the objective issues. Note_2: I used my review of the Beyer T1 headphone as the template for this written review, but very little of the T1 review text will remain unchanged here except for the music sample comments below. Those comments can be compared to the equivalent comments in the T1 review, and the few differences should give some insight on how the LCD2 compares to the T1. Many other recent reviews I've done contain these same music selections, with comments that are specific to those other headphones, and those can also be compared to the music comments below. Summary of sound: Since this LCD2 was a loaner**, it was already broken in and needed nothing more than a few minutes warm-up to get settled. My immediate impression was of a neutral bass, ideal midrange, and near-ideal smooth treble. The only EQ adjustments I made after 2 days of testing were a 4 db boost at 40 hz - per my preference for some extra impact in the deep bass, and a narrow 5 db boost at 8 khz, to add a little more 'presence' where I perceived a slight recess compared to 7 and 9 khz. There are very few headphones I've heard that I could play for an indefinite time with all or nearly all of my music tracks with no EQ or tone control adjustments, and this LCD2 is one of those. Other such headphones include the Shure SRH840 and 1840, AKG K712, B&O H6, B&W P7, Beyer Custom One Pro, FAD Pandora VI, and MrSpeakers Mad Dog. The EQ I described for 40 hz and 8 khz are very minor tweaks for test purposes, and would not be critical for users who understand the LCD2's target signature. **Head-Fi user Schopenhauer is the headphone owner. I'd like to go into more detail about the sound, but I'd like to be as objective as I can and avoid any suggestions about how much fun it is, or what genres it plays best with. My application is desktop use, and portability is relevant to me only in how easily I can move it and the source-plus-amp I'm using around the house, when I want to sit in another room. Nowdays you can drive this headphone with an amp that's physically small such as the Objective2, Portaphile Micro, or Decware Zen Head, to name a few examples. You might have success with a USB mini-DAC such as the Dragonfly or Microstreamer, but since those obtain all of their power from the USB line, you'll probably run short of power for transients on a lot of music with those DACs. Some people report major differences in the sound signature of certain headphones with different amps, but my experience says that unless you have a bad impedance mismatch or a serious lack of output power, the signature shouldn't change much from amp to amp. I think people who play mostly classical or acoustic music, or possibly jazz, will like the neutral bass balance of the LCD2, and especially the quality of the bass. I've commented on the midrange for every headphone I've reviewed, in some cases just saying that it's unremarkable if the colorations are so minimal that there's nothing to address. My first impression of this LCD2 was that the midrange wasn't exactly perfect, or so near perfect that I could skip to the next step in my evaluation. I found a few small bumps in the response with test tones, but after attempts to flatten those with EQ settings and not hearing any improvement, I went looking elsewhere and then found what I think is the only important deficiency or coloration - a sharp recess around 8 khz that slightly dulls the 'presence' or sense of realism. With that fixed as shown in the graph linked above or on my dalethorn site, not only is the overall sound closer to perfection, I don't find anything else to nit-pick or complain about. The LCD2 fit is good, with big earpads that should surround large ears in full comfort. The earpads are similar to those that issue with the Alpha Dog headphone - they're thicker at the rear and bottom, apparently to follow the shape of most users' heads (which taper off behind the ears). The earcups are mounted on gimbals, and a screw above each earcup is tightened to fix the earcups in place so they don't slide up or down. The LCD2 is fairly large and heavy, and while some users who aren't experienced with large headphones may adjust to it easily, many users will find it cumbersome if they expect to be able to move around a lot while wearing it. The headband adjustment goes about 1/2 inch smaller on each side from where I use it, to about one inch larger on each side, which should accomodate very small heads but not very large heads, based on my average-size head. The dual-entry cable is flat and appears to have 4 conductors, is very long (~10-12 feet), and is terminated by a 6.5 mm (1/4 inch) stereo plug. The LCD2 is an open-back design, so there's essentially no isolation. Leakage is total - i.e. the same as if you were using small speakers out in the open. The LCD2's efficiency or sensitivity is fairly low, and while it will play with adequate volume and frequency balance with some music tracks on iPhones and iPods, many will not play satisfactorily, and those that do will likely suffer some clipping even when it isn't obvious. Some of the small portable amps I use are also strained with the LCD2, so I recommend a good desktop amp with lots of power. Audeze recommends 1 to 4 watts, or 1000 to 4000 mw. According to their specs, the LCD2 produces 93 db per milliwatt, which would seem to be 123 db per watt. Still, I think something near one watt or 1000 mw would be a good target value for a headphone amp for the LCD2. The comments in the music tracks listed below can be compared to other headphone reviews I've done, as described in 'Note_2' above.
