SB3 lover here. Honestly the Duet has not caught me. Nicer remote, but who wants another remote? I hate more than 1 remote for any 1 system (Pronto 7000 for the main system). I prefer seeing "Playing Now" on the box itself.
FYI - 2 SB3s, and multi internet connections with SoftSqueeze. The whole family loves having access to all of the CDs.
Only about 520 gigs of FLACs so far. The server has 2TB in RAID 0+1.
Pio 94,SB3,BD30,A35,Pio 48AV.Pronto 7000 controlling all. Getting ready for 22s, 150 & QS8s.
