Less efficient speakers on AU 20000?

I have a totally restored AU 20000 (The resto cost a fortune) and I was wondering if it could handle a more demanding speaker. Should there be a problem running ProAc Response 3.8s? Please look at the graph below pertaining to my 3,8s.I just don't want to kill my recently restored Sansui.

I think you should be just fine, the 3.8s are not really any more demanding then any other garden variety 88 dbl sensitivity loudspeaker and your AU 20000 is very capable of laying down the gauntlet.

The impedance even stays nice and high, I'd call these a typical load rather than a difficult one, and wouldn't hesitate to connect them to pretty much ANY Sansui.

Paul Hovenga of Many moons audio did the restore. They say he does very fine work . I got the unit back a year ago and still haven't turned it on. I have all these very current hungry Infinity speakers around here. I did not want to hook those up to the AU. I found the Proacs and thought they could be a good match for the Sansui. We shall see. I just received two replacement woofers for the Proacs. Took three months. Ill put them back together and see what happens.

Considering you recently spent good $$$$ on bringing your AU 20000 back to spec
it is a good a time as any to see if she rocks the cottage or if all the money you spent was
ill spent.
I'd Crank her up and see if your tech is worth his weight in paid invoices....
