Ulf, I'm a bit confused now, maybe, because I've never seen the MPAV in function.
So, would it be a good idea to buy the thing to go with Avant?
In the Avant manual there is a device connected to Avant, which looks like MPAV, but might be some other device. Is there a better option?
How about adding pair of Beolab 4000 into setup?
I have to admit, that I've dropped off a bit from B&O development. My experience and love to B&O dates to my trustworthy Beomaster 1900-2 and Beovision 601 era.
