@AG - I chose the sunology because of its 4x Gig Ethernet ports that support link aggregation (in combination with a managed switch). This is VERY noticeable in how quickly tunes start streaming, and how quickly album art fills in on an iPad or laptop when using music control software. Also great when streaming high res tunes and HD video at the same time. Another factor - upgradeable to 4Gb of RAM.
Just let me to give you my experience. I have used Sasha I during 8 month. In my personal opinion there are a big difference between the old tweeters and the new silk tweeters for Sasha II.
Thanks for the feedback! Yes, it does sound nice - I actually replaced a pair of Wilson Sasha Series 1's w/ the Sabrinas. Proof that the 'best' speaker isn't always the biggest or most expensive, but rather the one that works best in your room.
The system is versatile as you mention - the Linn Akurate digital streamer means that anyone can stream their own tunes in there from an iDevice. Although it's not the highest fidelity, I have found that it's still much better sounding than most folks have heard their own music sound, so it can still introduce folks to good sound. And then you put on the vinyl version of what they just played, and minds get blown.
Custom printed acoustic treatment is next, using some of my daughter's photographs. And the WiFi lights, although I'm sure they add some noise into the system, are more than worth it for the mood setting and overall experience (they can change w/ the music using the proper iPhone app).
That is a cool room you have there. And some very nice gear. I am sure it must sound wonderful to be in that room playing some nice music. That Ikea rack looks excellent in your setup!
