Need help troubleshooting for a friend who recently installed a Denon 5800 and Sony 9000ES SACD/DVD player. He complains of zero SACD audio response when the player is feed a SACD. Says that Redbook and DVD's work fine. What hasn't he checked??

If he is using the digital link, then that is the problem. No SACD player will output digitally, you have to go analog. Thank the copyright industry for that one. (Plus, some people argue that the DSD encoded data of SACD degrades if translated to PCM like redbook and DVD, rather than using a DSD dac).

Actually there is a warning about sending SACD analog output through a receiver or preamp/processor that has Analog to PCM processing in the booklets that come with the new Telarc Multichannel/Stereo SACDs!


It advises consumers:

"BEWARE of Home Theater Receivers with DSP

Many multi-channel receiver/preamplifers provide multi-channel analog inputs that are routed to analog-to-digital PCM converters for Digital Signal Processing control, often at 44.1kHz. The signals are then passed on to digital-to-analog converters for the final output to speakers.


This "feature" will cause ALL signals, regardless of source, to be no better quality than that of CD playback.


Considering that you are playing an SACD with a sampling rate 64 times that of CD, we recommend using a receiver or preamplifier that passes the multi-channel analog signals through entirely in the analog domain.


Keeping the signal in analog, without any further digital inter-steps, will ensure you will be enjoying the full quality of SACD.


We further recommend that all "effects" programs be disabled, such as "concert hall," "stadium," "nightclub," etc. These ambience programs, which are more suitable for home theater use, will distroy the carefully mixed surround presentation you will find on Telarc surround SACDs. "
