Odd shaped Amps and preamps

So I am finally bored with the black boxes. I have a slew of black boxes everywhere and my wife feels (and I am starting to agree) that all our living spaces seem to be cluttered with rectangular black shapes.

I have set out on a quest to create something special and elegant and unique in form.

I have just created a set of triangular glass and metal platforms that glow with a soft blue cast. They are sexy as Hell and are begging to be filled with equally sexy gear.

The challenge:
List some amps and preamps for me that are circular, triangular or will otherwise fit onto a triangular shelf with 22" sides. Be as creative as you want. Tubes or SS, low wattage triodes or Class D Digital...as long as it is high end gear and not junk. I only need about 20 Watts for my speakers to sing but extra won't go to waste in my experience with them.Speakers being driven are Lansche 4.1 (with the plasma drivers).

Price is not really a consideration in this case. I need both an amp (stereo or mono pair) and a preamp.

Links would be super if pictures can't be posted here.

Thanks everyone!
