They are both worth it. How's about letting your ears decide! Having owned both Classe and Levinson over the years and different models each with their own traits, good and bad. On one system I have Aerial 10t's. I was using Classe M-1000 monoblocks. Exciting sound, powerful but lacking microdynamics. I demo'd a 336. Big microdynamics, but bass was ill defined and overall sound was just too "polite" for my tastes. Demo'd 33H BINGO! Not as "exciting" as the M-1000's, Better microdynamics, less bass however the best mids and high-frequency I've ever heard.
Some folks like chocalate chip cookies, some want oreos. Same with amps. Demo the Classe and the Lev!
Good luck
