I own the Yara Evolution Bookshelves too and will never get rid of them! They're just too good a speaker that's now discontinued. If/when they need to go into a bigger room such as your's, I'll still keep them and use them elsewhere. Here I was thinking I was the only one with these speakers. But anyway...
If you really like what you've got and are simply looking for more space filling and a step up in sound quality, have you considered the Tempos? They're my favorite in the AP line. There are better models, but I think the Tempo is the sweet spot in lineup. Close call with the Scorpios.
There's a gentleman selling a pair of Tempo IIIs for $900. No connection to the seller, just saying it may be worth investigating.
I haven't owned Tempos nor your integrated, but I'm lead to believe it should have no problems driving them.
