If it has a Dolby Pro-Logic II mode it must have an ADC since PLII is a digital process. The DSP modes are all digital as well, virtual, hall, live etc. In such devices, the only mode that is not digital is direct/bypass. Some of them even use digital processing on stereo since bass management, speaker level settings and sometimes the tone controls are all done in the DSP (digitally). -- Mark Lanctot Mark Lanctot's Profile: http://forums.slimdevices.com/member.php?userid=2071 View this thread: http://forums.slimdevices.com/showthread.php?t=29293 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Hi Mark, Unless I've haven't paid attention correctly, the Denon DRA F101 is strictly stereo audio, none of the fancy stuff you get on an A/V receiver. Additionally, it does have a direct/bypass mode, which is what I use, which bypasses the tone controls, etc., so I would suspect then that it does do ADC and then DAC unless you use the bypass mode. That's interesting, I'll have to do some listening and see if I can hear a difference... I learn (or think I do!) something new every day! -- nicketynick Wireless SB3, Denon DRA-F101, Mission M31 loudspeakers WinXP SP2 Slimserver, SMC WBR14g router nicketynick's Profile: http://forums.slimdevices.com/member.php?userid=1511 View this thread: http://forums.slimdevices.com/showthread.php?t=29293 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

I didn't look into what the model was because they use a different model number in each market, plus there are certain models only available in certain markets. -- Mark Lanctot Mark Lanctot's Profile: http://forums.slimdevices.com/member.php?userid=2071 View this thread: http://forums.slimdevices.com/showthread.php?t=29293 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Switching to the digital output into the the D/A converter on my Lifestyle it was much better - as I would have expected. Initially I put this down to the D/A converter inside the Squeezebox not being as good quality as the Bose one, however having read more about the Burr Brown D/A converter I may have been to quick to make that conclusion. I would like to move back to using the analogue outputs and am thinking about buying a high quality phono cable to make the connection. Before I do, I am interested to see if anyone else has had any experience in comparing the Squeezebox D/A converter with an external one. In short, was my sound disappointment purely cable related Try cleaning the connectors of the analogue leads. Make sure they are a tight fit.

I prefer the dac in my Arcam reciever to the dac in my SB2, however I believe someone else did the same test and prefered the SB2 dac. I was using a £30 analogue cable and a £180 digi coax though - maybe not a fair test a! Have been meaning to have a play with my new IC's for a while now but have not quite got round to it - The manufacturer sells a pair of rca to rca's as an IC set (which I am using them as)and a single rca to rca as the digi coax - same cable (which I need to have a shift around of gear to try one as a digi cable). However the Chord cables are sold as IC's and different cables as digitals. -- Deaf Cat Deaf Cat's Profile: http://forums.slimdevices.com/member.php?userid=515 View this thread: http://forums.slimdevices.com/showthread.php?t=29293 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

You're almost certainly better off with the digital connection. Your ears didn't lie! ...exactly. When I first got my SB2 (then SB3) and connected it to my receiver via analog, the sound was so warm as to be muddy. In comparison, the digital sound was crisp, almost bright. This was puzzling - surely the SB3 DAC was better than the Cirrus Logic DAC in my receiver? I attributed it to different handling of the analogue versus the digital inputs, principally due to sending it through the receiver's ADC. But I used the digital for a long time. Funny, around the time I installed 6.5 I tried again and it sounded much better? I have no idea what changed and there was a thread someone else started that noted this as well. Anyway, I've been using analog ever since. It's still warmer, but not as muffled as before. -- Mark Lanctot Mark Lanctot's Profile: http://forums.slimdevices.com/member.php?userid=2071 View this thread: http://forums.slimdevices.com/showthread.php?t=29293 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
