Sabrina X Anyone Add Subwoofer(s)

I've added the S/812 to my SabrinaX driven by the Gryphon Diablo 300 and as another user said, it just adds so much more than bass. I think the changes in soundstage are the most satisfying ones. Any speaker in any price range can benefit from that, given that the room has proper treatment / measurement / acoustics.

 By the way I am letting my pair of SabrinasX go, less than 1 year old. If anyone is interested, here's the link. 

I’m replacing them by the Magico S5 mkii

I went to the dealer to listen to the Rossini DAC to add to my system and ended up getting the speakers I demoed the DAC with.

The Sabrina is a great speaker, but the soundstage and imaging of the Magico is off the charts. It’s almost double the price but the Mágicos “disappear” way better than Wilsons I think and that’s what I am looking for at the moment.
