Mcintosh amp advice

Looking to swap out my PS Audio GCC-100 int amp and happened upon Mcintosh amps. Listened to the 6900 int where the salesman recomended to start and was in my price range. Loved the look and sound but have been reading about the 2275 tube integrated.
Which one is better with quad 22L speakers and how difficult is owning a tube amp, am not used to messing with tubes. To complicate matters i have a deposit on a new LFD int which i was going to buy off a review in Stereophile back in Mch along with some other peoples recomendations that this is a great amp.
the mcintosh 6900 new or a used MC2275 would be roughly the same money> would that also be an issue buying new or used.
Any and all advice would be greatly appreciated as i am in a dilemma LFD"s are backordered but i will need to make a decision soon
tks
