Amen ! How about the everlasting discussion on digital interlinks? An interlink of $600 sound much better than one from $50. Yea right. You have to be one bad designer to design an interlink not able to transport a digital signal over an approx 1 meter wire. Than there is always the jitter discussion with an expensive wire also does a much better job at.... -- SilverRS8 Author of -'AlbumCatalogCreator' (http://acc.vanholt.nl)- for Squeezebox'_' (http://www.badkamerpech.nl)Server . 1xTouch, 1xSB3, 1xDuet, 1xRadio, 1xiPhone iPeng, Ubuntu NAS + SBS ------------------------------------------------------------------------ SilverRS8's Profile: http://forums.slimdevices.com/member.php?userid=12818 View this thread: http://forums.slimdevices.com/showthread.php?t=77727 _______________________________________________ Touch mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/touch
