I haven't heard the Pathos, but I have heard positive things about them. You haven't mentioned a price range, but I recall seeing the Pathos used for @$1600.
If that's the range you want to stay in, you should consider the Prima Luna series that Upscale markets. They have been well reviewed and are self-biasing, makes life easy for someone new to tubes.
Personally, I have a Manley Stingray and a Carey SLI-80. Two totally different approaches to the end result of making music that makes me smile. I run both in the triode mode, which suits my listening habits, primarily jazz, blues & classical with some classic rock thrown in. These choices take you into the
$3000 range.
Consider your listening habits as well as your wallet. Try for an in home demo if possible. Happy hunting

, it can be fun if properly approached.
