I had a chance to try out the Peavey Headliner 600 head at the local store today. I played it through the Headliner 410 cab and got the tone I was looking for quite easily. The only other heads in the shop to compare it to were the Fender Rumble 350 and a Peavey Tour 450. To rate things fairly, the Headliner is a 300w head, but I was able to get at least as much volume from it as the Tour 450 through the same cab (there was nobody else in the store, so I was able to crank it up to past "music store" volume). I just couldn't get a tone I liked out of the Fender and the Tour 450 was lacking something as well. The Headliner 600 is no micro - same footprint as the Tour 450 and not feather-light, either. My question is: has anyone else had a chance to compare the new Peavey Class D offering to other amps at that price point ($300-400)? I'm mostly interested in how it compares to the Ampeg PF heads (the same shop also sells Ampeg, but I'd have to have them order me one). I live a long ways from the nearest GC, and the local stores don't carry a ton of bass gear.
