Then maybe the question should be, putting aside the fact that the nilai500 is unavailable until likely summer, and the NCx500 amps are said by the manufacturers I have spoken with will be out supposedly in late April, why would someone pay more and get considerably less? That is, with the complete NCx500 stereo amps are being priced below what it would cost to build a proper stereo nilai500 amp, why would anyone bother? If one really had a thing to build one's own amps, just buy the NCx500 amp, take it apart, and build it as you wish. What am I missing?
