Which solid state amp loves a 4 ohm load?

I am seeking your recommendations on neutral-sounding solid state amplifiers for around $1500 (or less) used. It will need to be a strong performer with a 4 ohm load and have enough power to fill a 60'x 20' room. However, I don't wish to sacrifice sound for power as I don't listen at high levels often enough. Speakers are Audes Blues and will work "backward" from there.

Thank you in advance for your expertise.
