I need a cheap ($300ish) integrated that will mate well with Mission 780 Argonauts. They are 4 ohm speaks that dip to <3 ohms so the amp will need to be rated for this. They are rated at 95db's and most listening will be at low-moderate levels as it's for my office. 50 watts (or even less) should be more than enough. I need a warmer sounding ss integrated that's good at low listening levels as the speakers can have an agressive top end if not matched right. New or used, do you have any suggestions? The 4 ohm gig has kind of got me stuck.

Thanks for all your suggestions.
