If you mainly want good clean tones there's any number of amps that will do. Lots of analog, solid state amps out there that produce a great clean tone. Crate, Fender, Orange, Vox, Roland, Peavey, etc., in many shapes and sizes. If I were in your shoes rather than focus on the perfect I would focus on just finding a good deal on an amp that pleases you. You will probably never find perfect, but you can definitely find "works just fine". Like the Rolling Stones lyric-- "you can't always get what you want but if you try sometime you just might find, you get what you need". Forget about the dirt channel, if there is one, and focus on the clean and how it sounds with pedals.
