Sorry, since I'm not iPhone user, was just curious. On Android phones/daps, there is no default "max" volume setting unless you use HibyMusic and set exclusive HQ usb audio access with usb audio volume lock; and maybe there are other apps they do similar. What I was getting at, if you set digital volume of your source to max and set RU6 gain to high, you won't have to push RU6 output volume at high.

no worries

tbh, listening at 60+ volume is unpleasant with the MKII; way too loud to be enjoyable.

iPhones transfer volume control to the connected DAC. Like a line-out. Adjusting volume on the iPhone does nothing while the RU-6 is connected.

I'm really curious why there are many complaints on clipping on iOS supposedly due to a lack of power because I've not experienced it myself, at least not with the RU-6 and the OEAudio cables. I did experience clipping with the W2 and ddHifi cables in the past, but I'm not suspecting the cable / device and not iPhones (at least not on the 13 Pro Max) in my experience.

iPhone 13 PM + ddhifi usbc to lightning adapter + cayin usbc to usbc OEM cable + RU6 + Monarch MKII 4.4mm + OS

RU6 starts clipping at 63 volume

I edited my original post to put the cable and adapter in. i have my OEAudio cable on the way, will test when i get it in.

i think by default, the RU6 sets the iphone volume to max anyways, so the volume on the device is auto set to max.

The volume automatically maxing out on the phone is what I get when I plug the RU6 into my iPhone 13 Pro.

For others, no clipping for me. I use the RU6 with IEMs (SeeAudio Bravery; Penon Serial, FAN, and Globe; 2021 Tanchjim Hana). I rarely go above 40 in low gain, OS mode.

Hi head-fiers,

Does anyone know if there are any advantages to couple Cayin RU6 with Cayin C9 ?
What are the main disadvantages ? Should double-amping be avoided at any cost ?
Should I use Cayin RU6 or Cayin C9 alone instead ? Why ?

I will mainly use this combo with my

• Sennheiser HD660s,
• DCA Aeon Noire,
• Dunu SA6.

Thanks to you all for your input

PS: I have posted the same questions in the Cayin C9 thread; if any one is following one or the other Cayin product thread only.

Hi there! Can anyone provide a brief comparison between RU6 and Ifi gryphon? I mean in regard of sound quality aside from the obvious difference in output power, Bluetooth functionality and price. RU6 has r2r implementation whereas gryphon has multibit dac and reviewers describe them as analog and musical sounding devices. I was wondering whether they have the similar sound signature or there are some noticeable differences?

It is not that simple.
The overall texture is the same by the means that both favor an analogue and organic sound signature, the RU6 a touch more.
But then the Gryphon has better technicalities, is dead silent, more refined, has increased clarity, more headroom etc.
Although not as visceral and holographic as the RU6.
If you don't mind the size the Gryphon is technically superior but the RU6 has a slightly more "tubey" character.

Dear friends, here is my take on the RU6.

https://www.head-fi.org/showcase/cayin-ru6-discrete-r-2r-usb-c-dac-amp.25607/review/28176/

Very addictive and analogue sounding.

Thanks for reading.

I found zero difference in audio quality of 3.5 vs 4.4
A/B test, I myself switch the toggle and even through, I heard nothing difference at any means.
So I must unplug a channel of RCA to verify I did not bunco myself

After A/B Ru6 2 output 3.5 and 4.4, I seriously try A/B Ru6 against SP1K output.

Insane? NO!

I know, I heard Ru6 by HD800S from day1 I got ru6 and found something special to draw me to the music.

@Andykong said SP1000 wins every meaning.
I today said ru6 wins SP1000 when feeding to the amp hdvd800.
(Both bal, se, all dac filter mode in AK)

Ru6 sound liquid, wider imagine (something like adding echoing but actually not), holographic, same clarity, nothing hash.

Idk why when UAPP shows a same moment on my smp(connect to ru6) and on SP1000, output of ru6 is much sooner (apprx 2 seconds!).
(All dsp off on Ak, try all dac filter include short delay)

Ak fw1.66cm
Super Slow roll off : the most close to ru6 but still 2D, not 3D like
Short delay Slow roll off: the most use of mine for directly drives hd800s. But sound worst when feed to the amp.
Mid imagine locate and focus at center, lacking detail overal
Short delay Sharp roll off (default mode): focus mid on center, forward, clarity than other modes, but I feel harsh abit.

Ru6 sounds something mix of Super slow roll off and Default mode but in 3D imagine.
Mid from ru6 so special! 3D, stay backward a bit, wide, realistic timbre.

Update: uapp is something wrong on AK.
Test with Default music app of AK again and I update later

Should double-amping be avoided at any cost ?

This issue also interests me. Can we couple RU6 with other amplifiers via line-in?

That's what I do when I use the RU6 with my xDuoo MT-601. It works well

LOL remember a while back we talked about dongle dac with battery pack? FiiO took a crack at it LOL.

Personally I don't need this but it's funny to see it being put into action.
