I just noticed that when I go to Sweetwater, the most expensive bass amps are still Class A/B and seem to be highly desired here on TB. High end tube amps followed by solid state amps such as an Aguilar DB751, GK 2001RB, Mesa Carbine, TC Blacksmith, SVT 3/4, GK Fusion etc. Only after those, do Class D heads come up. Does anyone one still prefer the tone or some other aspect of a class A/B amp over a class D head? Personally, I have 2 amps, one of each. A TC BH250 and a Hartke HA4000 which I recently bought to have a good solid amp at my rehearsal space and for gigs, which allows my TC to be a backup, which I needed. I'm questioning my purchase however. Not because of the tone or the amp it's self, which are both great, but why did I buy a heavier class A/B amp instead of a class D? I got the Hartke for reliability, tone and power, and it delivers in all 3 categories. But, it is also hard for me to question class D tone, power or reliability. I guess it seems class D is now preferred, but if you still prefer Class A/B/ amps, why?
