Before you drop 60000 on a 2 w SET...maybe start with something like this
It's a tube Pre-amp that also has an integrated SS amp or you can use the pre-outs with another tube or higher end SS amp + has a sub out.
Tubes ain't my thing though. I'd like to own one or two for novelty's sake but I can't justify something that intentionally changes the sound to make it more pleasing.. it's like "Happy Face" EQ settings. I'd rather have a high level SS amp giving me the signal as it was recorded.
