Gustard U18 with Gustard R26 dac?


Greetings.  

I've done some searching in the forum and I know there are people with the Gustard R26 dac and/or the U18.  I currently have a R26 dac and I'm quite happy with it.  I'm just wondering if I might get a bit of improvement if I add a U18.

I'm using the R26 with an Innuos Zen Mk3 streamer via a Inakustik usb cable. 

If I add a U18, I've read that the I2s connection would be best. Questions that I have are:

- is this a worthwhile upgrade? I think the rest of my system is revealing enough. 

- will I need an expensive I2s cable? 

- does the I2s cable need to be really short? I can make it work if I rearrange my gear. 

Thank you for any input.

That would coincide with what several others said in that a better — and sometimes a much more expensive — HDMI cable made a slight improvement.  I’m definitely gonna give one a try at some point, and if you get any clearer picture down the road I’m all ears to what you find, and thanks a lot for the follow up!

Great!  Thanks for the follow up and very much look forward to your impressions of the DH Labs cable. 

Nice!  Love to hear your impressions once it settles in. 🤞🤞🤞 And hey, if everyone’s grammar here was anywhere near as good as yours this would be a much more user-friendly place. 🙄

I added a Denafrips Iris DDC to be able to take advantage of the i2S connection in my Musician Pegasus R2R DAC. I honestly didn’t go in with high expectations and bought the Iris used so I could easily resell it if the improvement proved marginal, but it was far from marginal. Adding the Iris was on the order of doing a complete DAC upgrade — the noise level dropped so images popped more out of nothingness and the 3D soundstage expanded in all directions. And yes, ideally the HDMI cable should be 1 foot or less as the i2S signal degrades quickly over distance because it was initially designed only for internal connections within a component. As I was just dipping my toe in I bought a $7 cable from Monoprice mainly because it was available in as little as 6” length and I wouldn’t be out much if I sold the Iris, but as it was more than capable of conveying the substantial benefits I heard I haven’t felt the need to upgrade to date. I’ve read several people say they didn’t experience big improvements from spending a lot more on an HDMI cable for i2S so that may be at play, but if I did upgrade it’d be to the DHLabs HDMI 2.1 that gets solid feedback but still not too pricey. Here are the links to both cables in case it helps.

Anyway, that was my experience going this route and I know several others here expressed similar results so I’d definitely say it’s worth trying. Hope this helps, and best of luck.
