As far as the excess-decay in the LCD2, I heard that also loud and clear with the stock SE cable and it really bothered me. But as I mentioned above, the ALO XLR cables address this problem to a large extent.
With the stock cable, it seems to happen in almost all CDs, but now, it is reduced in all CDs and vanishes in many. In fact, I would say that with the ALOs, the midrange decay (and overall speed)
is equal to my T1s (stock cable, single ended).
I listened to my (very old) Johnny Rivers hits CD where his vocals have an annoying, almost ringing overhang. It was headache-producing with the LCD2 & SE stock cable, but was reduced enough
for non-painful listening with the ALO XLRs.Then I tried my T1s and noticed the same level of overhang as I did with the LCD2 XLRs.
So it sounds to me like the ALO XLRs, if not completely curing this problem, at least make it equivalent to a stock T1.
I tried some other CDs I know well and do not suffer from a loose midrange (Grass Roots, Carole King-Music, 3-Dog-Night) and the mids were also as firm as the T1s. And on my SACDs that I tried (Rolling Stones Hot Rocks and Boston),
things were totally tight and with no flaws at all and just provide what my hypercritical self calls an awesome musical experience.
I think this decay thing has something to do with digital glare, which is a tough test speakers and phones in general.
I also have PS1000s, and they seem to have the firmest midrange and best, most natural decay than either the T1s or LCD2s, and I turn to them for CDs that have this problem.
But the LCD2s are smoother than the Grados, and the upper highs are more liquid than the T1s. I love the upper highs of the LCD2s for their complete lack of bitterness.
