I am on the side that cable don't necessary improve the sound, but alters it to what one prefers.
I got the cable and here is a short review on LCD 2 /without fazor and LCD X.
On stock cable, the LCD 2 always was missing just a little bit of imaging, muddy bass, and overall clarity. Because of this the LCD 2 always had a very intimate feel to them because of their graininess. The cable change the way they sound and brought their performance closer to that of LCD X. If you like the classic sound of the LCD, I wouldn't change the cable, but if you want just a bit more of what the new driver have a cable change is highly recommended.
For the LCD X, on stock cables they sound like good monitor speakers. They have very punch lows and highs, you can identify where everything is, great imaging, but overall wasn't very musical because the instruments don't really blend when it is that punchy (think stax). Others put very high value on this separation, because it makes for great imaging, 3D sound, and live music feel. The cable warmed them up quite a bit. The punchlines is significantly reduced and they sound closer to a LCD 2/3, instruments blend together, with accuracy reduced. If you want to keep the sound of the LCD X or enhance it characteristics, I would not recommend this cable, because moves them closer to the main LCD sound.
Overall with effect of Q Cables on the LCD series, the changes don't require any A/B which is rare in the audio world, the notice are pretty noticeable right away.
For me the Q Audio cable did what I want, and it is a great cable from the simplicity, craftsmanship, and design cause getting a hold of 44 gauge litz wire is not easy.
