I listened to WP7's through the LAMM LL2 pre and ML1.1s with Siltech cables using a wide variey of music (excluding Rock and Rap) and never once felt the job wasn't being completed. I never turned the volume controls past 9 o'clock and the music was always fleshed out and dynamic. If you can swing the ML1.1s (now 2.2) do it. If you have a concern about power, get the M2.1/2.2. They are sonically close and over 200 watts but run Class A to around 30 or so watts of power. I own the M2.1s and drive Piega C10 Limiteds with them wonderfully. I was contemplating the WP7s with my LAMM gear because of the awesome experience I had at CSA Audio where I bought my LAMM LL2 preamp. It's going to be the WP7s against the ESP Loudspeakers Concert Grand SI. I can't wait.
