I think the question is best answered by the speakers you are wanting to drive. If they are flat panel tower Magnepans then I'd advise you to get an external amp.
Some 4ohm speakers are easier than others to drive. When my AVP needed to be sent in for replacement last year I put my (then) bedroom AVR - an Onkyo 506 in it's place. Since it had no pre-amp outs I couldn't use my external amp so the 506 had to drive four 4ohm speakers (cc was 8ohm). It did ok - never overheated or shut down and is still alive with a nephew. The 4ohm speakers were Emotiva ERTs front and ERD surrounds - and an 8ohm AV123 Bigfoot center. The 506 is certainly not rated for 4ohm duty but it did fine. I never pushed it but I didn't baby it either.
