How about the Art Audio Diavalo 13 watt integrated.
Also I think that the Pass Aleph series amps sound great with the Sonatas. I use the Aleph 2s with my sonatas and it sounds great. With the higher sensitivity Sonata 3s you could get by with the available used for under 1k Aleph 3 (which I think sounds even better than the 3x the price Aleph 2s)
