HOWEVER, I will also say that the Electic Amps seem to have a more heavy duty construction.
You've heard the propoganda and believed every word of it then...
Have you ACTUALLY seen inside a Matamp? All of the Matamp's I have seen inside of (quite a few!) have been superbly built and would be able to endure a serious pummelling, and many have and are still going strong. The fact that these amps are seriously over-engineered to make the valves last longer, and most of their designs are self biasing so you don't need to take your amp to a tech to re-valve & re-bias your amp every year is another credit to their detailed design and care they take while building the amps.
Plus you the waiting time for a Matamp is about 10-11 months less than the waiting time for an Electric Amp (as quoted on numerous sites, their waiting time is around a year, where Matamp'll have your amps built in about a month).
+1 on what Ted and HTH said... :roll:
