Steve, I'm extremely excited by this formula one project. Hope you don't mind me adding some practical "requests"
First> I know it's a way off yet, but can you take "pre orders"...any chance of jumping the queue before the queue?!
Second> any chance of adding a second I2S input?( in addition to the internal offramp usb-I2S)?
I for one as you may be aware use both a sonos and computer as source through the one DAC. Some forum members may wonder why. Answer because each has it's limitations:
Sonos: no 24/96. Zone player software not nearly as intuitive as itunes. Remote controller can't control other devices. Won't play DRM tracks.
Computer: no available sonos "computer zone player". ie Unable to link computer's audio into the sonos multiroom system.
Having both resolves these issues...until Sonos gets it's act together!
Third> For convenience the remote is a great idea Steve...(I've already written applescipts to contol IR signals from a MAC) but if it can't come to be, input selection must be accessible on the front panel (appologies unlike the Spoiler)...I know you say it can't be done Steve, but autosense on line source input would be amazingly useful when using a DAC with a music player like the sonos (or squeezbox for that matter). You see the way you use and contol this great multiroom system is all via the handheld controller....it might even be from a different room. When I'm walking around the house I'll often turn on the zone(room) I'm about to enter way before I actually enter the room....If you then add an Amp with autosense (like a Rotel or Linn)...you have a fully automated sound system to match gear thousands of dollars more.
Anyway Steve can't wait....bring it on!
