This is an interesting thread from both sides.
There is no denying that Nelson Pass is a legend in audio design along with the other famous circuit jockeys, Bob Carver, John Curl.
There are a couple of disturbing points if Nelson sent out a series of products that he knew were under performing that is pretty poor that he rushed the product to market when he knew the product could and should be better.
As per Dpac prefering Pass, that is his opinion with his matching gear, the Pass signature tends to be a bit laid back the Luxman is a more neutral sound, so it would all depend on cables, dac, speakers, room acoustics.
Pass is but one excellent choice if you like their sound, styling, size, Class of operation, and in the case of his Class A designs the heat output.
