Sharing a tip with fellow-cable swappers.
With the SE-5 Ultimate, I notice a difference in sound with cables.
Unfortunately, most aftermarket cables mess up with the sound signature of the SE5U, notably with bass control and soundstage coherence. Some cables also have a lose fit because their pins are too short, which led me to already lose one earpiece while travelling. I therefore much prefer - and recommend - Spiral's Ear stock cables. The two models, standard and "high res", are made by Plastics One (
website).
Spiral Ear is reselling them for $120 and $220, but you can buy them for a fourth of the price on Custom's Art website.
Curious to hear about your experience. Cheers.
My cable swapping experience is very limited, nevertheless, I've tried a few cables with my SE6 and it's very much related for me what you have described, even though it's a 5-way Ref thread and I haven't heard these CIEM's.
SE6 perform much better with their default cables and, from the ones I've tried, the ones that come close will be Plussound X6/X8. Default cables are much more coherent both in bass, but also in highs and overall resolution.
If anyone could share some other cable options for SE6 and perhaps SE5 that'd be appreciated. I've heard some Onso cables perform well with SE monitors, but I couldn't audition these yet.
A while ago I've asked SE about aftermarket cables and whether they could supply it with different terminations and got this response:
"We supply cables only with 3.5mm termination. Replacement cables will come with the following prices:
https://spiralear.com/more-info/ (for cable cost please refer to: "Remould/Service"). They can also be re-terminated by aftermarket cable companies into various configurations.
We don't offer a 4.4mm option with any of our monitors at the time being; only standard- 3.5mm.
Our cables are supplied from the pioneers of the industry- Plastics One, who had set industry standard specifications for IEM cables and connectors decades ago.
Apart from the industry-standard pin diameter and length, we order our cables from Plastics One with custom specifications and different parameters from the stock ones (both in material used as well as specific cable lengths), which is quite costly.
Regarding cables, any industry standard and quality, aftermarket ones will be fine (they obviously differ in design and ergonomics too, so it’d also depend on your needs). As long as a cable is transparent and doesn’t act as a filter by having various impedance, it won’t affect the sound signature of the monitors. It’s just a myth being repeated by ‘audiophiles’.
Please note that only industry/standard 0.78mm pin diameter cables can be used with our monitors (with a similar, lightweight plug housing, exactly the same pin diameter and pin length: 3.43mm):

Our warranty does not cover any damage caused by using non-compatible aftermarket cables.
