Look at the line of amplifiers from the Italian company Synthesis Audio. They have a line of EL84 tube integrated amps that sound really good for the money and look quite nice (comes in a variety of colors). These are not that easy to find in the US, but, they should be on a short list of good sounding gear.
I like the tube amps from the Hong Kong firm AudioSpace, but, they make normal size integrated amps, not particularly small in size.
