THD for amp alone, calibrated out the rest of the chain since I have line out on PGA Pre. Have you seen anything prettier recently?
Lets see... Looks like low 12vac range linear ac voltage supply with nice reliable sinewave.
I see nice full musical range+ flat frequency response with 115 dbl average.
I'm missing more bits I'm sure.
What speaker impedence!? Any long operational real music testing? Any performance dips due to long time operation temperature spikes.
How does it sound?
I'm new here and don't have enough experience to really say much... But don't let the haters or distractors keep you from doing what you do. I see alot of excitement for this amp.
Thank you.

PCB is also standard with 1oz copper.
I'm curious to know if the 1oz copper adversely affects the performance. Have you done any testing at higher output?
Ok, thanks. As I'm sure you're aware the application note recommends 2 oz copper and says output will be higher, lower EMI margin, etc. But they do not quantify they benefits.
After using Jlcpcb's assembly service I am no longer interested in assembling my own boards, however they do not offer assembly on 2oz copper.

If the conductors are wide enough, it does not affect. I tried this on early versions of my amp.

Ok thanks. Now I see on your site the output of your 3255 amp is very close to the TI reference design.
Very nice.
Mind sharing where did you source the casing from?
