Dear David,I have a Denon 3910 Universal Player that goes through 5.1 analog cables to my Audio Refinement Pre2DSP
The AR Pre2DSP manual states that "the input signal does not go through DSP processing but will be sent through by volume control and sent to 5.1 audio output"
I am all ears as to weather or not my system is properly set up for SACD listening. The Denon SACD light certainly comes on when I put in a disc. It also will show what channel's corresponding speakers will play from the disc..... L/R for two channel sacd's and L/R/C/RS/LS for multi channel sacds.
It sounds as though your AR Pre2DSP is set up exactly the same as my Rotel for SACD.
The real question is what does your DENON 3910 do?
Now my Marantz has two audio set ups. The SACD is set up on audio 2 set up.
Now you can specifically set the SACD to output from DSD or PCM. IF it outputs from DSD then the signal goes straight to the analog output ports and you can not change levels or delay. That makes sense as those functions are carried out within the PCM domain. You can only change levels and delay by selecting PCM and disabling digital out. The lights all look the same but you are only getting true SACD performance by selecting DSD processing. The instruction book is of course silent on these important
issues.
I have a strong suspicion that any player that sends an SACD signal out via a digital cable or allows processing such as time delay, is not really outputting DSD. I think if your player really is outputting DSD and you preamp is configured like ours you have to do level matching and route to the sub externally to the preamp. I suspect at least for classical multichannel SACD the delay issue is irrelevant, because they are discrete multichannel recordings. That means the rear channels are reproducing the signals from the rearward facing microphones. What is picked up by those microphones is already delayed by the acoustics of the recording venue.
