Onix SP3 or Jolida 502B?

A good friend is trying to decide between these 2 integrateds. We live in an area where auditioning either is impossible, so he is going by posts and online reviews.

I would like to get your thoughts on these 2 integrateds? He wants to run 2 sets of speakers, one has a 92 efficiency at 8 ohms and the others are 94db at 6 ohms. Should that be a problem for either of these?

Thanks for your thoughts and feedback.
