I own Pass's class A amps and a Red Wine Audio Signatue 30.2 (Tripath chip based). I use the RWA in the summer months in my home office and enjoy it a lot. If I didn't, I would just crank the air conditioning and keep the Pass's running. Might not be enough power for your Thiels if you like it loud.
"Out" perform the Lev's? Who knows. Probably not. Depends on what you value in your listening experience. I think you would gain some areas, lose in others.
