Hello everybody

I am rather new to B&O products in general, but what I like the most so far in terms of sound are Beolab 18, Shape and Beosound 2.

Here comes my question: I plan to set up a pair of Lab18 plus (probably later) a Lab19 Sub, and to connect both Lab 18 and 19 to the Core. But how? I heard or read somewhere that connecting Lab18 to the core via Core´s optical out would provide the best sound quality. Could anyone who already tried this please confirm that using Core´s optical and Powerlink outputs in parallel would not result in any sync issues (delays) between the two?

Is the Core´s optical out perfectly in sync both with its analogue output (Powerlink) and other Multiroom speakers (if present)? I am asking this as I plan to place a Beosound 2 (via Multiroom) in another corner of the same (big) room, and as I have always been pretty much finicky about any noticable sync issues.
