It's mainly driven by the power rails that were available. Op amps are cheap but getting clean power for them is not always easy. In SB3 we had access to higher voltages because the display used them, whereas in Receiver it would have required quite a lot of additional circuitry to increase it by 1.2Vpp. Receiver 4.8 vpp versus 6.0Vpp is only lower by only 1.9db. I can easily detect the volume difference in a/b, but I can't hear any sound quality difference between the two products if they're level matched. > Reason I'm asking is that, in my experience (compared to a couple of CD > and DVD players and a DAC), analog output of SB3 is already on the quiet > side, and I believe that that's the main reason that it's being > percieved as being of an average quality.

A CD player with more than 6Vpp output would cause serious problems as it would clip all kinds of A/V receiver's inputs, although it is not unheard of for manufacturers to juice it by just an extra db or so to give them an edge is subjective listening tests. -- seanadams ------------------------------------------------------------------------ seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=42570 _______________________________________________ jive mailing list [email protected] http://lists.slimdevices.com/cgi-bin/mailman/listinfo/jive
