Well, "know" is a strong word... I've not examined the circuits. But I did search the internet extensively and found some statements that seemed to be credible which stated this. Interestingly in relation to your earlier post about 2.1 vs 2.0 ... there was an additional claim that in analog mode the processor actually switches to an analog method for filtering and driving the subwoofer, so you could get 2.1. There is of course a lingering doubt in my mind, which is perhaps one reason why I've ditched the Denon 2805 as an amplifier for my Transporter and gone for entirely separate 2ch/5.1ch setups!! The only thing I can assert confidently is the entirely subjective judgement that my SB2 sounded better driving the Denon in analog mode, which I think was the original question!!! As for the volume control, its surely not hard to construct an analog electronic volume control which is driven by a digital control source (I'm fairly sure I remember designing such a thing myself in the very distant past!)(remember that its only the actual signal path that has to be analog) Ceejay -- ceejay ------------------------------------------------------------------------ ceejay's Profile: http://forums.slimdevices.com/member.php?userid=148 View this thread: http://forums.slimdevices.com/showthread.php?t=31497 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
