Impression from a newbie - JMT answered question after question; did not try to 'sell' me on anything but his answers were so informative I learned enough to consider an upgrade from the transportable I was ordering.
Just received an email from him to let me know my gear has shipped - the entire transaction was incredibly smooth and I felt "dialed" into the loop at every step. He even sent me pics at the midpoint of the build - suggested some amazing improvements to keep with my aesthetic goals (come'on you know if I'm going to order a customized amp I'm going to *customize* it, right?)
To make a long story short, I got incredible service and attention, I really felt like I was ordering a Ferarri - in this case it turned out to be a fully loaded PPA with Black Gates, Nichicon Muse, diamond buffers, dual headphone outs, 627 socketed op-amps with 825s and more to roll, bass boost and crossover (which I may never use but hey, I was being thorough) improved power supply - the only thing I didn't add was the stepped attenuator but there is room for that if needed in the future.
Thanks Jon for everything. <-- Another satisfied customer.
