As for the listening impressions:
First off I will say that adding the HD621 to the v4 was a huge improvement as I watch more movies these days than I do listen to music.
I use the 800v3 with SPDIF(MHR) going into the v4 and now the v6 and lately have used the Oppo via HDMI into the HD621 for music also(I use it extensively for Bluray).
On the v4 I still preferred the 800 for all music but with the v6 I was amazed at the improvement on the Oppo for music. I am hearing more detail in the midrange and the bass is tighter. I am not sure why but I suspect the MMHR SL connection was the reason. I would say the Oppo surpassed the 800 (sad to say for the 800) for music. The 800 into the v6 sounded as good or maybe slightly better than with the v4 but was lacking some of the detail that the Oppo had.
As for Bluray movies I would say that the v6 was another moderate improvement using the Oppo and HD621 into the v6(again I suspect because of the SL connection from the HD621 to the v6).
I am thinking that the HD621 is doing the apodizing and upsampling in this chain and the only place that the v6 apodizes is when I use the 800->861. If that is wrong someone can correct me. In the 800 the display shows 88k and the 861 shows MHR Music2 88K for redbook CD's and the yellow lights are on -- on the speakers (or the dots for older speakers).
....... Regards
Joe
Thanks Joe for the report.
If you want to make a fair comparement between the Oppo and the 800,
you have to turn the 800 upsampling off.
Now you are compare a CD with standard(no apodizing) upsampling in the 800 with a CD
played in the Oppo and have the apodizing upsampling in the v6.
Can you turn the upsampling in the 800 off and compare the Oppo and 800 again?
When you turn on the diagnostic display in the Mconfig,
you can look for the audio stream.
When you play a CD, you can see on the display if the HD621 make the apodizing upsample or the 861V6.
Was the Bluray music/comparement with a natural hires signal, means more then 48kHz and more then 20 bits?
When that is true, the v6 itself could be the reason for the improvement(mybe better dejittering)
or the SL between the HD621 and v6, or the SL beetween the v6 and the DSP/AC12.
Looking at your signature, you have standard 8k- not 8k2.
That means you have the AC12 invalved now and with the v4 the standard SPDIF.
Is that true?
Where you have placed the AC12(how many)-near the v6 or near the speaker?
Can you tell me the cable lenghts for each front speaker from the v6 to the AC12(SL) and from the AC12 to the standard 8k(SPDIF).
Joe I guess you have upsampled in the 800 before with your V4-
are there any improvement (only for that combination with the 800) between the v4 and the v6 ?
Joe , can you also make the DAC resolution test?
Thanks again
