In the past week I've wired up my first TDA7293 paralleled and it was a piece of cake compared to paralleling LM chips. No close-tolerance resistors required, no sharing resistors either. I'm running 4 TDA7293s in bridged-parallel and it works great. I doubt I'll be going back to LMs in parallel unless longer-term listening reveals problems with sound quality. Initial SQ impressions are promising.
