Used NAD like you were considering before or something new-direct from Schiit Audio are going to sound worlds better than the Emotiva or Yamaha IMHE.
What exactly is your budget. Are you looking for an integrated amp?
Your speakers both are promising and will easily let you hear the benefits of higher quality amplification.
Hopefully, your speakers are on decent stands with spikes, are off the wall behind them and you are giving some thought to basic room acoustic issues(e.g. thick curtains over windows, and a thick rug over hard flooring) if not yet investing in any real room treatment panels, etc.
Cheers,
Spencer
