i have had my peavey mark 6 xp series head with matching 4/10 cab for years now. i love the sound it makes. done many recordings with it and sound engineers say what a lovely sound it produces. i even left it out in the rain one night all night. gave it two weeks to dry off. and it still works 100%. built like a brick these things. ive just bought a ashdown magIII 500 head- only becuase i got it soooo cheap. and to be honest the sound is no better than my peavey. just shows you.
