After getting into the setup menu and selecting "input" continue scrolling until you come to "CD". On page 2 of CD make sure that Auto Surround is set to OFF
If you have Auto Surround set to ON you will not you will not be able to use the multi surround modes in the R-972 like " MCH" or multi surround stereo when you do turn Trinnov on. When you have Auto Surround turned to OFF you will now use Remastering + Pure Audio + Trinnov. Go to page 3 of the CD page and set Trinnov to however you want. Then turn on Remastering and Pure Audio. Pure Audio will automatically set the R-972 to stereo which you will see in the speaker diagram in the left of the R-972's screen that will show the two front speakers plus a sub, but Trinnov is still engaged.
Now turn OFF Pure Audio and you will see all the speakers that are in your system appear in the left of the R-972's screen. It is now with Pure Audio turned OFF that you can now use all the cool surround modes in the R-972 + Remastering + Trinnov.
By the way, Pure Audio's function is to make the audio cleaner by 1) turning of all video processing circuitry inside the R-972 thereby eliminating any interference from it on audio. 2) It changes the R-972 to Stereo only mode (2.0, or 2.1) which takes all the audio information ordinarily sent to the center and surround speakers and sends it all to your front L/R speakers. To me this sounds the best.
No matter which route you go, stereo or multi-channel, you have the flexibility of always being able to turn Remastering and/or Trinnov off. It's all about what sounds best to you!
This time I made sure that all my settings were matched and tried the analog inputs with Trinnov engaged. I first tried it with plain jane and it sounded good, then I added remastering and it sounded about the same. When I added Pure Audio the sound was noticeably louder so I stopped it right there and grabbed my tri-pod and Galaxy CM-140 SPL meter. With the volume at -10 I measured 86db with No
Remastering or Pure Audio, 86db with Remastering and 89db with just Pure Audio. Remastering + Pure Audio brought in the same high level at 89db so it is Pure Audio that raises the volume by 3db.
I went ahead and found the level that matched the 3db increase so that I could fairly compare at the same levels. At first I started at -13 when Remastering + Pure Audio were On
that gave me and average level of 86.3db. I then switched the volume to -08 for my HDMI input which gave me an average of 86.6db so the levels were evenly matched for a fair comparison. The levels were averaged from 3 measurements each with the CM-140 C-weighted, slow response so that I could make it as fair as possible.
First thing I noticed was that with the levels matched the analog input with Remastering + Pure Audio still sounded a little louder so I went ahead and dropped the volume to -14 which gave me an average spl of 85.4 db compared to the 86.6db level of the HDMI input at -08. After listening to the same track I used to measure it sounded more evenly matched so I went with it.
I will say that I could hear a difference in more detail and more weight to the sound, it still sort of gave off a sense of being just a tad bit louder as well with the analog input with Remastering + Pure Audio vs the HDMI. You could tell the volume was the same but there just seemed to be more information in the music if you understand what I am saying. It is hard to explain the difference but I did prefer the analog input with Remastering + Pure Audio. There is one specific track in particular that I had played in a friends house and noticed a detail I wasn't picking up at home. With analog input that detail was much more clearly defined that you could not miss it.
I also compared the analog input with and without Remastering + Pure Audio. Even without those 2 processing modes I found my-self preferring the analog input to the HDMI and while engaging Remastering + Pure Audio did make a subtle improvement it wasn't as big as analog input vs HDMI.
I am assuming we are actually just comparing the DAC's in the R-972 vs the CD or BD player. Even though the 972 is converting the analog to digital then back again to apply Trinnov it is still getting a different signal to begin with via the analog vs digital connection.
I really have to spend some more time with it though to know for sure, it is much more subtle when the levels are matched. My initial reaction though is I am listening to music via the analog input with Remastering + Pure Audio. I have to get a friend to switch it for me though so I can do a blind comparison to really know for sure.
Thanks for teaching me something new islandman
