I'm sure Nelson is rolling his eyes and biting his lip.. Power is not the feature most would associate with quality. Huge power is available from the pros for use in stadiums and other public arenas. Most such amps are now some kind of switching amp, and powered by 3 phase electrical services not available in a private residence. Few DIY projects include the extensive protection and diagnostics that professional products include. But even in such situations, its probably better to use a smaller amp per speaker than wire a huge array of speakers on one huge amp. Amps bigger than (pick your number, I will say 100 Watts), are like muscle cars somewhat useless vanity. If you want impressive sound levels, you need to bi-amp or tri-amp, not use a Kilowatt amp. In the professional world, reliability is very important so connecting any speaker to an amp that can damage it is unwise. And that includes gradual failure over an extended period of time. And most larger amps are not the finest sounding amps. Designing for power and robustness is generally at odds with designing for stability and low distortion. No one drives a dragster on a road trip.
I second Kevin's comment.
My Neurochrome Mod-86 and Diff 8x2 Pre have been favourably compared to Trinity Reference gear (Reference Line – Trinity l the perfect sound).

Standing Committee on the Law of Patents - EXCEPTIONS AND LIMITATIONS TO PATENT RIGHTS: PRIVATE AND/OR NON-COMMERCIAL USE
250kB PDF file from WIPO
Laws do vary.
"In some Member States, by definition, private use and non-commercial use are excluded from the scope of the patent right."
It is interesting the US is not covered in the WIPO study.
In the US we have Tommy Jefferson's later thoughts that inventors should be allowed to monopolize profit from inventions, but must reveal the invention to allow others to study and improve upon it. In practice this may mean making your own private copy to study.
So are you saying Passlabs' own 600W class AB X600.8 and 300W class A Xs300 don't have any real-world use cases? I mean they clearly aren't targeting the pro-audio users.
