Hi,
The user ends paying nothing for a kit of parts directly from the factory as he does not buy them. In fact the WAD Preamp Kit is gone and not available at all.
But clarly you are someone who would expect to go to a Porsche Dealer and pay the same for a brandnew Porsche there as you would for a parts kit fror a factory direct selling Kit Car. Dream on.
Well, a substantial number of noted reviewers (and customers) seem to disagree with you. But sound is a subjective thing. I can even imagine someone prefering a 20 years old used NAD Preamp, except that person is unlikely to be me.
Ciao T
