Those are my favorite ones. Have you tried getting them from here? They are official partners to Symbio in the UK.@samandhi , when you are referring to the Symbio tips, do you mean these?
I am currently using the SpinFit CP100+ together with the KBEAR Rhyme cable. Listening to Amazon Music Unlimited through my Qudelix 5K, LDAC. The result is amazing for me! What truly impresses me, though, is when I am listening to YouTube [Vanced}. I use it to discover new music, and because the DJ sets available there, are not available on Amazon. It feels fantastic immersing into the sound and forgetting everything else! It's truly awesome!
I haven't used the stock cable much but what I recall is a thinner sound, much treble and not feeling the base. Perhaps, maybe for sure, it was because I've used it just in the very beginning, prior to burning in. I would give it another try but it doesn't worth it for me, because my Timeless are meant to be used with my FiiO UTWS5. So, very soon, I will disconnect them from any cable.
Tips are more important to me. The sad thing is that these tips are not available on Amazon UK. These Symbios, for example, are currently unavailable. Similarly, it took more than one month for my CP100+ to arrive from AliExpress, same for my KBEAR Rhyme. It becomes exhausting, after a point.
I also use Amazon HD as my main streamer, and YTM for discovery.. Nice! Ultra HD streaming is a great thing to have, and I find that Amazon HD has pretty much everything that GPM used to have (which includes obscure stuff I couldn't find anywhere else).
I haven't used the Rhyme on these, but after cable rolling for a bit (including iBasso pure silver, and Dunu DUW-02 cables), I keep coming back to the stock one. I have tried a few Tripowin, Fdbro, Yi*** (banned), etc... also.
Yeah, I only order from AliExpress when all else fails. You can pretty much find anything there, but unless you pay an exorbitant shipping cost, and want to pay large VAT, you're stuck with China Post shipping (which seems to be the slowest in the world). Not to mention that this time of year, the whole country is off work for a whole month..
I am planning on buying one of the Rhyme because it seems to be a very good cable (for the money) from what I have seen here on Head-Fi. I am just waiting for the Amazon.US site to get some 4.4mm TRRS back in stock. Currently I can only get 3.5 SE.
