I'm uisng s Genzler Magellan 800, had it for a while now
Prior to that had a streamliner, which I really liked, had opurtunity to pick up the Genzler, figured it would be all the streamliner was and more
Wasn't wrong, it doesn't have the valve pre amp, but it's such a versatile am with a wide range of tones
I'm using it with Vanderkly 2x10's, I was giging this a lot, using just one cab when needed. With two cabs I had a nice compact set up that was is capable of some serious volume
Realy like what I hear about the Darkglass amps, wouldn't mind trying one at some point, the Microtube Mk1, the later version looks more complex, simple is good for me
Back to roiginal point, Genzler is good for me and I've had some nice amps over the years!
