I have owned the Cayin N5 for about four months now and am very impressed with both its audio performance and its build quality. My battery life isn't that great, but I typically only listen to DSD and 24-bit/192KHz FLAC files at moderately high volume levels, so I'm not too surprised at that. Overall though, I think the N5 a great DAP with a near perfect form factor and until I find something that sounds just as good (or better), possibly with a more modern user interface (touch screen driven would be nice but not necessary), it will remain my DAP of choice for the foreseeable future.
To the point of this post; I am in the process of building a couple of new cables (for personal use only) for my N5 to pair with my Shure ES525 (and other) IEMs. What I'm wondering about, in particular, is the balanced output jack on the N5 and how it's wired. Does anyone know? Looking at the 'DIY Cable Info and Resources' page (under the 'DIY and Mods' topic), there appears to be only one 2.5mm TRRS configuration listed, which is for 'Astell&Kern' devices (and I assume, others).
Is that (A&K) the standard for 2.5mm TRRS connections and is it the same wiring configuration used on the Cayin N5? I'm assuming it is, since there are no other 2.5mm TRRS wiring configurations listed on that page. If someone (Andykong, the Cayin sponsor, or whoever else might know) could confirm or elaborate on the subject, it would be greatly appreciated.
Thanks!
