I am not familiar with most of the gear that you have, but I have had several Nelson Pass products, including the Pass XA100.5, XA60.8, the First Watt M2 and J2. I also own a pair of Lamm tube amps. They each have their own character, but I have to say that all have these things in common: accuracy, good dynamics, and most important, they are musically superior to everything else I have listened to over the 15 years I have been an audiophile I had a Bryson amp, 4bt I believe, several years ago and I found it to be very analytic. It was accurate and it had good dynamic presentation but it was not very musical. Just my “2 cents” worth.
