If I was to buy a new head, to replace my SA450, I think I would go with this model: MoMark Black 500
. I love the module idea.
There seems to be a lot of love for the Little Mark Tube 800. The Black 500 has the tube preamp with semi-parametric mid controls and a class A/B
amp--which is supposed to sound a bit more vintage than the class D (800), from the reviews I've read.
I'm not against class D, at all. I just couldn't be happier with the sound of my current rig and it's a class A/B amp.
