Dear Primare
I have heard some N core amplifiers in three different setups,
at my shop
at the manufacturers facility
and the New York Audio Show
I have found these amplifier so far to be incredibly over rated, clean but lifeless sound, good bass control but no midrange magic.
We compared these amps to a pair of much more expensive conventional amplifiers and there was no contest.
Don't believe what you read on these things, the hype with the comparison's to the best solid state
