Last question bother you all with. If you had to choose between the Micro Tube (with the upgrade), and the MK 3, which would you buy? I am looking for the most enjoyable experience, not exactness. That doesn't mean that clarity can take a back seat, though.
I have a micro tube and the tubes are inside of it rather then top mounted like the MKIII. If you have kids or pets this sounds like a good way to go. I used mine to power my 701s and they sounded pretty damn good i think.
I don't think a fish or two will make a difference, but as I said, I am accident prone, and I have friends who are careless. Let's just say that is sat on my desk in the back of my bedroom (that's where I spend most of the listening time). If one of my friends just tossed one of my shirts or something, and it hit the amp, would there be any damage? I know tubes a kind of durable, because one kept falling out of a guitar amp and didn't ever break.
