I have the LCD-2 Rev. 2 paired with a Schiit Lyr Amp, and a Asynch USB DAC feeding that at 24/192 through use of Moon-Audio BL-1 Silver Sonic RCAs. LCD-2 Rev. 2 is connected to Lyr through the new FLAT stock Audez'e Cable.
I had recently returned a pair of HE-500 due to a design flaw in the gimbal which caused the whole headband to detach from the earpiece. Therefore I switched to the LCD-2 Rev. 2.
I am having difficulty understanding the love for these headphones. While I don't think they are "bad" headphones, I think the HE-500 absolutely kill the LCD-2 Rev. 2 in every sound category, except maybe Bass. The soundstage is extremely closed-in, leading to what I feel is a lack of detail and separation. Highs/trebles seem subdued, things such as snare drums and cymbals seem distant and lacking, almost to a point where I feel they sound un-realistic.
I have also owned HD-650's, Denon AH-D2000, Grado HF-2, Alessandro MS-1i, and MTPCs in the past. So I feel I have enough experience to be able to know the differences between brands and the sound profiles accompanying each.
Bands such as Beirut, Devotchka, Dave Matthews Band, and Counting Crows all struggle using these headphones. These bands could all be considered "hybrid" as they share unique instrumentals in addition to rock-type instrumentals (guitars, drums, etc.). Instruments get muddled, vocals seem to cover up details from the background.
I feel that Female vocals are not anywhere near as good as they could be.
If anyone has recommendations on how to improve my experience, I'm all ears (literally, the LCD-2's are on the stand).
