Hey.

So I've been looking forward to stepping my game up, and after a month of research, I found that the 650's are exactly what I want.

However I'm struggling with the selection of a tube amp to drive them before I order them.

I have always thought that I preferred bright sound, by recently I've wanted to try the warm sound of a tube amp.

I'm looking for a neutral but fun to listen sound. Prioritizing fun over clarity. I'm not looking for an analytic sound

I've heard they are both great, but I would like to hear everyone's opinion on both of 'em or how do they pair with the 650's

One pretty big point to consider is that the Crack is currently on a pretty decent sale. Meaning that I could get the Crack + Speedball for the same price than the Valhalla 2.
