Default suggestion for a 15W amplifier?

Hi everybody

i need a second amplifier, since i use the first one i built some month ago just for watching dvds. My power needs are quite low: for my room and my speakers, 10 to 20 watt is a good choice.
The problem is: what amp should i build? to be more clear: i would not like to build a gainclone-style amp, since i already have an LM1875 based amp. Moreover, there are a lot
of class AB desgin, but all the ones i've seen are rated at 50W or more.....Moreover class
A, which often comes with lower power rating, would require massive heatsinking and huge power supplies...
Any suggestions??
Thanks a lot!

I dont know what you can do or expect

But the new little Holton amp might be interesting fore a pair of very small monos
Or a very easy going stereo
Cant be easier than that
And from specs its supposed to work down to 10V rails
But around 30Vdc would most make sense
