Man these are sweet right out of the box - you don't want to know what I was using in the interim. Seriously, these sound much better than I thought they would out of the box. I listened to some expensive systems lately too. Everything is either native 24/96 or upsampled flac sent through Nova Sabre DAC and its tube pre into Sophia power amp (for now).
I have to wire up the sub through my tube amp but for now the Nova line out is feeding it.
I can already tell with only 1.5 hours, these are winners and they integrate nicely into our limited space.
Never heard a full range driver, ever. This is going to be a lot of fun.
