Thanks for the responses. I know that people have found SS works. My thought was that the CAT JL2 is a different tube animal, that wattage doesn't tell the whole story - it's how stable the amp remains under difficult load. What I've heard is that the CAT is quite stable and may be more so than many SS amps. Any thoughts? Gregm - you heard an actual JL2/Obelisk combo? Very interesting. Any other description of how that worked? Thanks again for everyone's responses.
