+1 the -13dB attenuation actually serves as good overload protection if you get some bug in the Transporter that outputs a burst of noise or anything , 10db reduces the potential power to 1/10 . So direct driving is safe if you have proper attenuation for gain staging . And as you say proper gain staging makes the loss of S/N with TP digital volume inaudible for all practical uses . and noise is noise in either analog or digital form a digital volume control is more precise in many aspects so it can actually be the better choice (for example perfect channel balance ). ------------------------------------------------------------------------ Mnyb's Profile: http://forums.slimdevices.com/member.php?userid=4143 View this thread: http://forums.slimdevices.com/showthread.php?t=95634 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
