I know it's too late, but from my experience with the NAF Legend-II amplifier I can tell you that careful matching with cables and speskers is essential.
Thus, it sounds awful with my Silverline Sonata-III speakers but sounds marvellous with my Nightingale CTR.2 open baffle speakers.
It is excellent with classics, less so with Jazz, and does not "read" poor quality CDs - it becomes constrained and unnatural. With good quality CDs it sounds rounded and full-bodied.
