I was just about to create a new post asking about experience with the HEOS Drive HS2.
I will be connecting an analog input also from a Rotel system aux out, today or tomorrow...
My build has the four amplified zones used from the Drive as well as using an analog out from one of the zones to feed an aux in on the old Rotel system driving a pair of large B&W floor standing speakers in the same space as a pair of bookshelf speakers being driven by same zone from Drive.
A delay would definitely suck!
