Gs5556, I didn't really doubt you, I was just ribbing you. I don't dismiss low power - I've just never been set up to exploit it, as I like to listen to all kinds of material, and at higher levels than your amps would drive my Thiels. You are an explorer, and diverse too - hope your SET's and homemades work out well.
Bryhifi, despite Elevick's misgivings, you will not be in danger of damaging a tube amp by presenting it with a lower-than-optimal-impedance load, due to the self-limiting nature of the beast, but you won't get the power you paid for either. So I wouldn't worry about "failures", just sound that might not be up to what you've been used to in certain respects. But since you say you just want to get your feet wet before jumping in, who am I to say that you're risking not being persuaded by the results? When I ran my 2.2's from the MV-55, the combo did sound better than my previous SS amps, but those weren't even in the same county as what you normally use. Best of luck!
