Just got my LL and I'm really enjoying it so far with my 009s. I haven't heard the 009s with any other amps, but this setup is revealing across the board--though subtle--improvements over my LCD-3/LF combo. The most noticeable improvements are an increase in clarity, a more expansive and 3-D soundstage, and a seemingly much wider dynamic range (i.e., the contrast between softer and louder passages in music). Whereas the LCD-3's tonal balance may have been tilted to the darker side of neutral, the 009's tonal balance seems to slant towards the brighter side of neutral, to the point where I'm experiencing a vague sense of fatigue during long listening sessions (and I don't consider myself to have treble-sensitive hearing at all).
With the 009s, I feel the power of crescendos more viscerally than I ever did with the LCD-3s, to the point where I often find myself fumbling for the remote to my PWD so I can tone the volume down. This increase in perceived dynamics may be due, in part, to the 009's slightly bright nature, which might be making the higher frequencies pop out a bit more at louder recorded volumes.
As was the case with the LF, I'm not able to turn the volume dial on my LL very much before it gets too loud. I'm using the balanced output of my PWD, which, granted, seems to have a high output level. However, if I set the PWD to 60 volume (which is PS Audio's minimum-recommended level to avoid loss of resolution), I can only set the LL at a few very slight turns above 0 for most of my computer audio collection.
Is this extremely low volume level limiting the extent to which the LL can produce dynamics or resolution, or am I just being paranoid? Am I better off using the LL's single-ended inputs to lower the gain and get a wider volume range?
