Of course you can't - hence my conclusions drawn from real-world experience and evaluation over many gigs.
It's worth mentioning that I was an early adopter - my journey with Class D began about 20 years ago. At that time, there was no hype for me to get swept up in.
Maybe there's a head with a different power module from the last few years that does the job? I dunno. I'm still seeing more and more people coming out to say class D isn't for them.
It's a moot point for me anyway, I've found the perfect head for me, and it's not exactly big or heavy.
