My short take on LCD2s:
Pros:
The bass is fine, controlled and deep and detailed.
The treble is fine, sweet and liquid.
Soundstaging is wonderful, with lots of micro and macro details, convincing image separation and boundaries, along with realistic shape and size and differentiation.
As for tonality, there is no grain, and things are not held back or blunted.
They are heavy but very comfortable, even for long sessions. Headband and earcups are well padded and pleasing, and the stock cable is fine, not too heavy or bothersome and not subject to microphonics.
They do well with solid state amps, and don't require tubes to sound lush.
Cons:
With vocals and piano and some other things in the midrange and upper midrange,
there is a kind of syrupy quality or ringing that can be annoying, especially compared to Grado PS1000s, Senn HD800s, and Beyer T1s,
which all seem more controlled in the midrange, especially the PS1000s, which sound rock solid there and is one of the things I really like about them.
Otherwise, pace and timing are fine. But still, piano decay is not as firm as I would like, and female vocal could be a little more recessed for my taste.
The LCD2s have better low bass (deep and expressive) and highs (mellow but with lots of color and sweetness) and better staging than any of the other 3 phones.
As of now, the PS1000s and T1s are still my go-to phones, but I will play around with the LCD2s some more with cabling and such because they do so much right.
***UPDATE*** I have since gotten ALO balanced cables and these negative qualities are gone. Somehow the ALOs cured these problems and now the LCD2s are superb. (See my post below (#7776) for a revision.)
The ALO cables really transformed the LCD2s into something much superior, much more controlled and refined, especially with vocals and the midrange in general. I love these cables.
System: Rudistor RP010B amp, EMM CDSA cdp, Stealth Indra ICs, TelWire and Stefan Endorphin power cables,
and sometimes a Val Alstine Ultra+ EC tube amp (upgraded with nice RCA 6CG7 tubes) added to the loop for some tube-goodness, treble-reduction (the Van Alstine has maybe the best tone controls
I have ever heard, great for the the 800s, PS1000s, and T1s), and remote volume control.
