I found U16 has a better performance than SU-6 with R7 and Reference 1.
Yes, I have used the R7, S7, and M7S (fully upgraded XOs) with all DDCs I have including Off Ramp 5, U16, SU-1/6, and F1. In this thread (maybe R7 as well) around April/ May 2019 I commented regularly about R7, S7, and M7S and how they compare. The short stroke of it all the R7 has better highs, more detail, and supports DSD. The PCM1704 DACs are warmer in comparison, the highs more vague, and less resolution. But I enjoy the old DACs and they sound better than ever with Accusilicon XOs and firmware changes. But you can only go far with these DACs as they are not as transparent as the R7. I am impressed though with the R7 as it is a firm and solid technology upgrade over PCM1704 DACs..
If a DDC sounds better with the R7 it sounds better with the older DACs. HDMI I2S in all cases. Haven't found anything contradictory in my use. Kind of makes a little sense as the DACs digital boards are the same running the same firmware
Rumor has it that Kingwa sold his U16 and is designing a DDC that is suppose to be better than all previous boxes - a U16 'slayer'. 10Mhz external clocking as well (maybe higher end model). So waiting on news from that effort.
And another rumor is that Kingwa is designing an R7 that uses 10Mhz external clocking. And also newer firmware is around the corner after testing. This all rumor BTW....
@PeterCraig The Accusilicon upgrades are for the newer Singularity digital boards. Not compatible with the old M7.
But I enjoy the old DACs and they sound better than ever with Accusilicon XOs and firmware changes.
I keep saying I need to sell the old M7 as I also have a factory version of the same hardware (S7). Maybe I will this time (but probably not).
is it hard to replace the clock with the accusilicon ones?
Any update?Yes, I have used the R7, S7, and M7S (fully upgraded XOs) with all DDCs I have including Off Ramp 5, U16, SU-1/6, and F1.
