Use HDMI if you can.
HDMI can transport high-bitrate lossless multichannel bitstreamed, SACD DSD and PCM audio. Optical and digital coax can transport only lossy multichannel bitstreamed and lossless stereo PCM audio -- not lossless multichannel nor DSD. Optical provides some ground and noise isolation which coax can't, but the two transport the same digital signals.
- What setting in the DV 9500 should I output, PCM or bitstream? (The DV 9500 is at least 5 years old now) I assume setting it to PCM will shift the decoding duties to the 8801?
It depends... Set it to bitstreamed if you use S/PDIF (optical or coax) for multichannel audio; either bitstreamed or PCM if you use HDMI. (DVDs don't have multichannel lossless audio tracks -- that's a consideration only for Blu-ray players.) The decoding should produce the same audible results, whether it's done in the player or the pre/pro.
-I assume the DTS Neo X surround option only benefits you if you are running an 11.1 system?
It should be able to expand any audio source which has fewer channels than the number of speakers you have so it uses all speakers, similar to DPL-IIx.
- I am curious what your thoughts are to listening to SACD,DVD-A via HDMI vs 7.1 analog. I tried HDMI (via my OPPO BP 83) but the rear surround disc info defaults to the side surrounds which is not what I want. The 7.1 analog hookup allows me to route the rear surround info to my rear surrounds which gives me a better listening experience for my high resolution multichannel disks. Is there a way to route the information to my rear surrounds via the HDMI route.....other than switching speaker cables :-(
Audyssey room equalization can't be applied to the 8801's multichannel analog intputs. The sonic improvement provided by Audyssey should be quite noticeable, which is a reason for using a digital connection (either HDMI or S/PDIF) instead of multichannel analog. Of course, that'll use your side-surround channels. Neo-X or DPL-IIx will expand 5.0 or 5.1 soundtracks to use both sets of surround speakers -- both side and back. If you don't like that, you might consider getting an external speaker switch. Or connect both HDMI and multichannel analog and switch the receiver between the two inputs depending on which sounds better to you.
-My 8801 seems to run a little hot, it definitely is not cool to the touch. Is this normal?........just wondering what other folks are experiencing?
My understanding is that most of the current model D&M equipment run hot because of their video circuitry.
-when you have a component that you have hooked up both analog and digitally, is there an easier way to switch inputs rather than going into setup and through a couple of menu choices? My Marantz receiver has an A/D button for this but I am not finding one on the 8801.
If the same control code doesn't work for the 8801, you might consider connecting the analog stereo connections to a different logical input -- CD, for example.
-I have only run Audessey once, it changed my front speakers to large (I am running dual Outlaw LFM 1 EX's and Onix Rocket 850's up front) so I manually changed them back to small. If from what I've read on this forum, this will not affect the room correction that Audessey has performed?
Always set all of the speakers to Small so that bass management is enabled, and raise the speakers' crossover frequency to 80Hz if it's lower. (Don't lower it if it's higher than 80Hz.) Neither change will disturb the calibration.
Audyssey provides the frequency at which the speakers' response is down by 3dB. Code provided by the equipment manufacturer decides if that's low enough to call a speaker Large. For details, please consult the Audyssey FAQ at http://www.avsforum.com/t/795421/official-audyssey-thread-faq-in-post-1
-As well, at the start of the Audessey process, I adjusted both sub volumes to read 75 dB for the test sweep, however after it was done, when I checked the levels, the subs were adjusted to -12 dB each which is above what is recommended(+/- 3 dB). If I run the sweep again but lower the sub volume to below 75 dB, I'm afraid there won't be enough bass with the final result. Am I missing something here or should I just trust Audessey implicitly?
A setting of -12 means that Audyssey turned down the 8801's gain as far as it could, but the subwoofer was still too loud. You should keep turning down the sub volume and recalibrating until you get a reading close to 0. Audyssey provides a large enough signal so that you'll hear the bass intended by the person who mixed the audio tracks. If you still find it too low for your preference after a week or so, turn up the subwoofer's gain in the 8801, not on the subwoofer.
-lastly, I have JVC RS 20 projector that I believe I am feeding a signal to that has bypassed the video processing in the 8801. Is this a good idea or should I turn the video processing on in the 8801? Generally speaking, is the video processing best left to the BR player, 8801 or the projector? Not quite sure how to turn it on or if indeed it is off right now in the 8801 (video conversion?, I/P scaler)......I hope that makes sense! Very complicated and confusing :-)
Use the processing which provides the best picture
The 8801's video processing is not supposed to degrade the video coming from the player, so leaving it enabled should be fine. Using a separate video cable connection from a player to the display device (if that's what you're doing) usually is needed only because the receiver or pre/pro can't handle high bitrate 3D or 4K signals. The 8801 can handle both.
