If you need only one input, there are some amps that have volume controls built-in that can act as a single input integrated amp.
One of these is the David Berning ZH-270. It is a 70wpc tube amp that is self-biasing, has very long tube life, excellent reliability, and is commonly compared sonically to some of the most expensive and respected amps in the world. Unless your speakers are very inefficient, this should drive them very nicely. The only thing about it is that it is not a fancy showpiece, it is only a plain looking box that sounds great. Be prepared, there is probably a waiting list to get a new one, and used ones are rarely seen. When you do see one, it is about 80% of the new price because they hold their used value about as well or better than anything out there. Reputation is legendary.
