You need to tell us what speakers will be used. I personally love tube amps and have owned various ones for 23 years. However, I also like tube pre-amps and the well designed ones are virtually maintenance free. Maybe replace the small tubes every 3-5 years depending on how much you leave them fired up.
There are damn good SS amps such as Plinius, Ayre, etc. However, if your speakers are amenable, I'd look into tube amps and not worry about upkeep, etc. I have an EAR 890 which is about 2.5 years old and I'm using the same power (big) tubes. Importer has told me they still have another year of two left. Years ago I fretted and worried about sutff like leaving the amp on, how many times I turned it on and off, etc. I now just use it when I want (it makes beautiful music) and realize the KT90 is a very easily available tube.
Also, you might let us know what kind of music you like and how loud you listen (along with IDing the speakers being used).
By the way, I agree with everything Newbee said.
