Hello Haylo
I have a pair of Thiel CS 3.6's which are also 4 ohm loads. I went with separates ... I picked up 3 Yamaha M80 2 channel amps and an Onkyo Integra M504. The Yammies are stable even with 2 ohm loads. I use one of the Yammie brutes for the Thiels. Never a problem. I use a separate processor - I picked the Integra DTC 9.4 but there are many great processors out there in the price range.
For spec junkies, the specs on the Yammie M80s are superb:
Continuous power at 8ohms 250 wpc THD 20Hz-20KHz 0.003%
4 ohms 330 wpc 0.07% THD
Damping factor 250
SNR 127 DB
A good used 2 channel amp can be a great buy and if you have the room, a breeze to drive your speakers.
