Can you share your older Pass Labs experiences?
Earlier Threshold that Pass designed were the best for me, as they were Bi-Polar output stages (not mosfet) and had far better current delivery. Plus you didn’t get what some describe as the "Mosfet Mist" sound.
Here’s one of his ground breaking Threshold monoblocks

And the classic affordable favorite Threshold 400A

And then even earlier was the best sounding but low power True Class-A 40w which I later expanded to a huge 150watter and used a self contained water cooling system in it. (it was still a two man lift)

Here are some diyer’s pics that built the A40 as it is
