MA2275 or MA6900 or MA6600 for 805 Diamond

Quick question, I don't have separate room and system for music and TV, Can I use MA2275 all the time to watch TV/movies/ps3 also with music. Will the cost of maintenance of tubes will be more or should I just go with MA6600 or MA6900.

Or should I go with Arcam 600 or 400 and do bi-amping?
