Cayin RU7 Dongle: Spectacular Sounding! 

Glad to hear you came out of that panther pink thing...😊

Hi @JtwasLuck and ​ @amplifyaudioreviews I acquired a Senns HD660s2. Usually drive on M1 Mac laptop or a android phone. and use Apple's lossless music streaming service. I don't need a separate AMP right if I get RU7 to drive my cans? I want to avoid any desktop set-up. Have a DC03 Pro, which is great for my IEMs, but just about manages with 660S2 - and I can feel the need for more power to make the headphones sing as they say. Would RU7 do that? And when you mention about the battery, let's say I have it connected to the USB of my laptop, which is also connected to power, there is going to be no drain at all right. THe 5 hours factor that you mention comes only when connected to phone. Most important question is this: Will it work like a proper amp and make my HD660s sing with its sound signature? (I feel since 660S2 are organic natural referency sound, this could gel well) Please do reply when free. Too many choices, in particular DC04pro, or even Hify B6, and am a touch confused!

No it’s not. Far from “hands down”. The iFI Go Bar is immediately and audibly better.

@@morespinach9832 Sorry but a dongle that has hissing with IEMs is not "audibly better", on top of that if you don't want hiss, you have to deal with a change in the FR of your IEM. The RU7 is miles ahead and its not even close. Remember most of this stuff is subjective, its very likely you are just used to the artificial sound that lower end delta-sigmas have.

@@Maheshutube Sorry I just saw this, the RU7 will be more than sufficient for the 660S2. You will most likely want to run it on DSD128 or DSD256. As for drain, its not a problem esp. if your laptop is already connected. Hell even on battery mode, the battery drain from a laptop is not much. I would only worry about battery drain if you are running straight from your phone. In that regard I would stick to the lower DSD settings to maximize battery life.

I appreciate that!

I doubt that he is familiar with Hindi. :D

@@TheVeganVicarhe knows hindi very very well 😅

@@sharmanihal, he doesn't look or sound Bharatiya, but I'll take your word for it.

how are you connecting the RU7 to your iphone? I'm using the camera adapter and the RU7 won't even turn on unless I also use the power connector on the camera adapter too.

@@jsuno23 Hi, I use a USB-C to Lightning cable. I mostly use one from DDHifi, but most any should do. I often place my phone onto an Apple charging puck unless I'm mobile.

Will try to get my hands on them!

@@amplifyaudioreviews please do, I think only Akros on RU-vid already reviewed both. And even compared the Neon Pro to the Anole VX (which personally I tend to find it a bit of a stretch, but, stil...) 😅

I have same question, how it responds to IE 900 ?

These will make vocals sound incredible with the sennheisers, its a very good pairing!

@@JtwasLuckhow about the ie200? Lol that’s the only Senny I’ve got other than pc38x.

Get rid of your ie200 and go get a set of AKG N5005 from Garmin for only $159. It used to be $1000 IEM. The AKG superior sound over the IE200 is more noticeable than blowing $300 on a dongle over a cheap dongle like a Fiio Ka13. In fact, the AKG sounds even cleaner and more spacious than the more expensive IE900. You can thank me later!!! Lol

I wanna know your current setup with IE600, buddy 😅. I drove them off of dongle dac on my Samsung phone and it is no fun. I have Salnotes Zero and I see very small difference between these two. I am lowkey regretting spending money on IE 600 now 💀

Over the Go, yes! Haven’t heard the Gold Bar!

@@amplifyaudioreviews Thanks!!! I'll assume the Gold Bar too. That is because although the Gold Bar sounds better its a marginal improvement. Probably a 10% improvement. Noticeable, but doesn't sound like a totally "differen"t device..

Yeah desktop or with android phones

Everybody seems scared to answer that question.

Thanks bro! Let me A/B these two and get back to you!

@@amplifyaudioreviews That would be awesome and it will help me make better purchase decision for me top priority is detail retrieval and bass impact.

​@@amplifyaudioreviews So what's your conclusion?

Why diablo? Even the Go Bar which is similar size is much immediately and audibly better.

@@morespinach9832 I was asking for that comparison because I own a Diablo. I actually bought the RU7 and have been enjoying it very much! Do you mean that the Go Bar is better than the RU7? If so, what are the differences that make you say it's better than the RU7?

@@antonristo1096 quite simply the sound. The textured bass, the sound stage, and the slight warmth while being super transparent. The go bar has a delicious grunt. The Cayin RU7 is a step down from the pretty decent RU6 imho. The 7 is just very cold and clear. Lifeless.

@@morespinach9832 Okay, thanks for the response! I enjoy a smooth and neutral sound with a tight and punchy bass response, and I feel like the RU7 has that, but I will consider trying out the Go Bar in the future!

@@morespinach9832the go bar is more musical than the ru7? I have the m15 and wanting to get an r2r dac. Choosing between fc6, ru6 or this ru7. For reference i came from a denafrips ares 2 so been missing that r2r sound. What would you suggest? Im only using og timeless tho.

That's what I am also interested about

I have no stuttering on my iPhone 13 Pro Max with the RU7. I mentioned it above just now, but I was surprised to hear that issue in this video...

@@rkatsanes It only happens to IEMs with a lot of drivers, on balanced, at high volume. I guess the dongle reaches the current limit of the lightning port.

@@ROCKSTAR3291 Thanks, makes sense I suppose. My HP and IEMs are both planar magnetic, and I seem to have no issues with those at least.

@@rkatsanes i don't know, the Lightning port restricts the power drawn from your phone, so the dongle might not be operating at full potential. Better to use it with your Macbook or Ipad.

in short m15s is more pleasing to hear straight wo amp

yes, best imaging for it's price. Sound is very similar to the HD600/650/6XX/660s family... but with better bass and imaging. Comfort is unmatched. I know because I own the R70x and HD6XX.

​@ROCKSTAR3291 thanks bro, between hd 660s and r70x which have better imaging and midrange, What about r70x Soundstage

@@sumanthduggirala1887 Soundstage on the R70x is not wide, but still wider than 660s. Midrange has a touch of warmth, while 660s is more neutral. It’s a matter of taste, personally i like a bit of warmth. The 660s is a darker sounding headphone, very little bass.

No. Igual mqa es una mala broma.

RU7

@@amplifyaudioreviews thank you 😊

Yes

thanks

I am non American and not even from any western countries, but I can clearly understand every single word he speaks. Maybe you need to learn to understand English..

I can clearly understand him. Im from Asia. You should improve yourself

@ccromato turn on auto subtitles.. 😅
