I'm definitely willing to pay for it just to make it possible for you to experiment with it so we can get something really great in GEN2.

For GEN2 I definitely want the faster CPU/memory to make it more future proof.

Anything else I need in there? > For GEN2, some kind of line-in would be nice if you believe GEN2 in the future could be packaged in a case with built-in speakers, the line-in on the Squeezebox Boom can be really useful if you want to use it as a speaker for external sources like a smart phone or similar device. If you think a product with built-in speakers would require a completely different board, a line-in doesn't make sense at this stage. IR and HDMI would also be of interest for GEN2, but that has already been mentioned earlier. JohnSwenson wrote: > > The big question is, should it have a headphone jack.

For GEN2 something with similar audio quality as the Squeezeboxes is probably a good idea. JohnSwenson wrote: > > Also should it have a TOSLINK? > In my opinion the S/PDIF is enough. However, if you can add the TOSLINK without adding a lot of complexity or cost, having both TOSLINK and S/PDIF in GEN2 could be nice for people who only have free TOSLINK connections in their DACs/Amplifiers. ------------------------------------------------------------------------ erland's Profile: http://forums.slimdevices.com/member.php?userid=3124 View this thread: http://forums.slimdevices.com/showthread.php?t=97881 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/discuss
