I have R7HE21 (Equivalent of MK2). It has USB Isolator, I2S Isolator, HE Power supply. It seems to me that we find these in the DI-20-HE. It really looks like the R7HE21 has a DI-20-HE built-in. So how can the difference be that huge ? I just don't understand how...Please explain. I'd like to...

Why ? R7HE21 (or MK2/3) have same Amanero board, same Accusilicon clocks. Please explain why using DI-20-HE is better. if it's better, it means something is missing / wrong with the R7HE21 (or Mk 2/3). I just can't understand why it would bring improvement with R7HEMk2 (or R7HE21 which has...

Hello. Does a DI-20-HE improves the sound quality of a R7HE21 ? Both have accusillicon clocks, seems the DI-20-HE is already built-in within R7HE. I'm wondering if the DI-20-HE is a worthwhile addition for my current R7HE21. Any feedback welcome, thanks.

Hello, How can a DI-20-HE improve the sound quality with a R7-HE ? Both have USB isolator, FPGA, Regenerative Power-supply... isn't the DI-20-HE already built-in with R7-HE ? How much is the improvement ? What connection is used between R7-HE and DI-20-HE ? Many thanks

If you were sending a sine wave as output; NOS at 44.1 khz: It won't look as sinus but your brain will interpret this as sinus. OSx8: It would look at sinus but it is "interpolated" data : On real music, it will create "fake" data. It will sound smoother but sometimes less real. Too beautiful...

Got my Pearl 48 0.5 hdmi cable. It might be a little better than the basic HDMI but not by much. The USB still provides more trebble but I like the more downward sound of the HDMI cable in fact :-) Not sure that be able to say which is best in fact...

Sure but OS8 does that in R7HE :-) Roon can do it up to 192khz and R7HE can reach up to 384khz also :wink:

I use my R7HE21 in NOS mode. I prefer, it is more alive. When I want to upscale, I put the R7HE21 in OS8. I'm not asking the computer to do it. Even though, if I want I can ask Roon to upscale to 192khz with Audiophonics card. I have received the Audiophonics card: It's good. Depending of...

What is puzzling is that HDMI is LVDS symetrical design which should be more immune to interferences. So it's strange we need better HDMI cable than the basic ones...

Well... Got my https://www.audiophonics.fr/fr/dac-...pour-raspberry-pi-spdif-i2s-tcxo-p-15821.html (Took this one because R7HE reclocks the inputs, did not see the point going with IanCanada more expansive setup) Setup: R7HE21 in NOS mode. HDMI Cable: Basic one Optical : Basic cable. Power ...

When I meant option b) it was with an audiophonics i2s board of course. Will I notice a huge imporvement over USB ? Is a good power supply needed or a simple USB 5V 3A power adaptor enough since my R7HE21 has isolators on HDMI input ? Thanks.

Hi Guys, Using R7HE21 and Roon. 2 options here: What would be your choice ? a) Rock Server + Rock USB Player b) Rock Server + RPI 3b Roopieee HDMI output Currently using option a) but you do think option b) is worth investing ? Thanks.

Kingwa told me that difference is really minor. The mk2 is just easier for Kingwa to build but from a sonic point of view they are similar.

Got and R1 and R7HE. The R7HE is of course better but it's not night and day. I could live with the R1. But the R7HE brings a little something (more texture, hard to describe). To me it was worth it because I can listen for very long times and I'm fairly picky. Kingwa used to build loudspeakers...

Kingwa is a true genius, his products work so well - even entry models - and his prices are really fair. I would like to see Kingwa make loudspeakers again.
