Cayin RU6: R-2R USB Dongle DAC with Head-Amp

[abitdeef]

I was thinking along similar lines. It would be nice to have a microsd card slot and a simple navigation to navigate the folders. In the same form factor as RU6 and priced $300 or in the form factor of Cayin N3 pro with less thickness and priced similar to N3Pro ($375-$400).

Yes thinner and maybe even a bit shorter with full Android for 400 lol. One can dream.

Now with the latest firmware you can use W2 with Nintendo switch etc.
The UAC 1 mode been added.

Just out of my own personal curiosity cause a few people asked me about usb dac dongles and Nintendo Switch compatibility, what is the advantage of using audiophile grade dongles with Nintendo Switch (in UAC1 mode)? The reason I'm asking, my youngest loves playing Mario cart on his Switch. So, is there anything else you can run on Nintendo Switch that needs a higher sound quality, besides playing video games?

No, not really, you can watch Netflix but it's not as nice as on your phone. It's primarily for gaming.

I received my RU6 earlier today and have spent the hours since conducting listening tests and power measurements. The RU6 clearly is an upper tier device from a sound standpoint with the flexibility to offer NOS and OS modes. While both sound good, I find my preferences to be NOS for large instrumental concert hall genres while to me, the OS mode seems more realistic for more intimate acoustic and jazz genres.
Contrary to some earlier posts, I have found volume adjustments to be totally silent and muting is imperceptible during adjustments.

I will avoid any subjective comparison of sound between the RU 6 and several of my other favorite dongles as personal opinions will vary due to listener preferences and hearing anatomy, however I thought power comparisons between dongles might be informative to all.

I streamed my own lossless music files through each device with the volume set to my own comfort level and didn't make changes between dongle swaps.

The RU6 was set at Low gain, NOS and 70 on the volume scale using the SE output. The comparison dongles had no adjustment settings. SE was chosen as not all of the dongles have a balanced output.

The IEM used for measurements was my Shozy Black Hole as these are neither particularly difficult to drive nor are they super efficient. Impedance is listed as 16 ohms.

The results are listed from most to least power draw:

Hidizs S9 Pro. 140 MA, .68 W
RU6 2-R2. 120MA, .59 W
EarMen Sparrow. 90MA, .44W
Questyle M12. 90MA, .44 W
Periodic Rhodium. 20MA,. .10 W

Hopefully, these comparisons will prove useful in determining the suitability of ones source devices.

Mine pops sometimes around 50 volume and 20 volume does anyone else's do this? Andy is this normal? What's weird is it doesn't do it everytime changing volume. It's quite a loud pop.

Looks like W2 is still superior after all, here is an impression from a user posted on a rather popular audio discussion forum in China. Below is the post translated into English using Google Translate.

[Pre-declaration] The following is only representative of personal opinions. Personal level is extremely limited, and knowledge and level are as low as that. The following assessment has no merit and is only used for personal entertainment. If you have any doubts, it is your right, and it is my honor if you have any recognition.

[Repertoire for testing]
1. Yanni Acropolis concert CD track
2. Four Seasons-Summer, third movement, Malinowski version, purchased from HiRes store
(the above are all iphone11 seashell music output, ios The system is naturally exclusive)

[Earplugs for testing]
Ruixian D3, I don’t want to toss big ears at home in the morning, so I took D3 to play with it. After purchase, I only listened to it normally for about 60 hours, with a 4.4mm interface.

[Sound features]
RU6: Lubricating and gentle
W2: Clear and gorgeous
UP5: Warmth
S2: It’s hard to say a word

[Personal subjective score] See the table below

[Personal subjective conclusion]
1. W2 is still the best overall, but the gap between RU6 is not big , The latter has not started as a new starter, I believe it will improve if you listen to more. The two styles are obviously different. The second choice for classical listening is W2, and RU6 is popular for listening to human voices.

2. S2 and UP5 are obviously in the next tier (but in fact, S2 and RU6 are almost the same in price). UP5 is listening through Bluetooth connection, but the overall listening experience is still better than that of S2. I actually like the Letu brand very much. The Moju in my hand is also very popular and recommended by everyone, but S1 and S2 are really not flattering. S2 is obviously stronger than S1, but the analysis, sound field, overtone and stability are not satisfactory.

3. UP5 is the most convenient for daily commuting. Use ifi idsd nano bl to relax at work. Do not hinder the work, but also can get a point of joy. S2 plans to keep friends who are not so feverish in the future. W2 and RU6 will leave home to work overtime and go home when they don’t want to turn on the computer.

So nobody else experienced popping while changing volume?

Lol that's just my opinion, one thing for sure though the leather case on the W2 looks way better and more premium

So W2 sounds best for classical. Thats sort of what I inferred from the test tracks.

 

[Stuff Jones]

I bet the R01 sounds sweet. Andy did say there is actual burn in on the resistor type dacs. I'd like to see them make a smaller r2r dap. Something that wouldn't be as heavy or expensive as n6ii+ R01.

N3Pro w/R2R please.

You have the ru6?

Thanks. Anyone have a translation for the column headings?

 

[propolis12]

Would like to see serious comparison with earmen sparrow

 

[abitdeef]

So the S2 gets 2 out of 5 stars? Not that it really matters.

 

[Zachik]

N3Pro w/R2R please.

That is EXACTLY what I asked from @Andykong for a few weeks ago...
(and a better processor to fix the crappy GUI of the N3Pro)
