Something I watched a while back regarding old Marshalls said the 100 watt models usually peak much higher when they’re cranked up, and I wouldn’t be one bit surprised if that’s the case with the HDRX 20 as well. The fan in my Captor is singing when I use it, that’s for sure! That, and the MT15, are definitely pushing out some gig-worthy power. I would put both of them at around 40 watts if I were blindly rating them.
My Sweet 16 seems much closer to the advertised power rating - it’s “tame gig” volume, which is actually a good thing, because that’s the overall vibe of the amp, and getting it turned up is more achievable than if it were pushing like the HDRX 20 or MT15.
I think these little amps from PRS are fantastic. Lots of power and authority, unlike many of the lunchbox amps, and really, in 2023, if they’re not enough power for one’s live needs, they should probably evaluate their overall volume and PA situation.
