I was in another thread earlier that was asking about best class D amps? Like the Berg B amp, D800+, Darkglass, Puma, etc.. now I'm wondering how some think the Rumble 500 head stacks up to these higher end heads in terms of sound, quality, and headroom? I know the build quality and wattage isn't there with the Fender but how significant is it? I've owned for the past 30 years of playing starting with Ampeg SVT, SWR SM900, GK2000rb, a SWR 350 red face which I still have, all heads mostly played through an SWR 610 I had ( doing original rock band stuff) always had tons of head room, tone, and great dynamics with these rigs... then 10 years ago and getting older I started the whole cover band thing (R&B, Funk, Motown) and all I mostly need is a 112 and good small class D head for restaurant/bar or the occasional outdoor gigs where I use 2 112. The heads I've been through are GK mb500 both heads and combos, Kustom KXB500, GK mb200 which I still have and like the tone for a class D amp but lacks power and dynamics, Traynor SB, and all have left me sort of blahhhh and wanting my old stuff back but in a smaller package... And now I've been using for the past 6 months a Fender Rumble 500 which sounds great and easy to get a usable tone, but am I still missing something that say a higher-end and wattage class D amp can produce?
