Wattage should not be a big issue, and I have run low and high power solid state and also OTL's with fine results.
And hey TooBlue, I have both 1's and 2's. And the 1's are in daily use but the 2's are for sale, although I do not have an ad up currently.
I am not sure why, but the 1's are my clear preference over the 2's also.
Enjoy!
