Detailed and lightweight does not describe the CJ PF-2L I know. In my home office system I still use the Motif model I believe it is based on. It could describe one that was not left on long enough for it to warm up/break in (there is no on/off switch, it should be left on at all times).
Have you considered the Adcom GFP-750 ??
