Wow, what a gem of a thread. Thank you for all your efforts @ClieOS ! 🙌

A quick question — I just got a Qudelix 5K but all my cables are 4.4mm balanced… could anyone suggest any quality/reliable adapters to go from 4.4 to 2.5 which wouldn’t impact SQ? Or is it a bad idea to use an adapter?
The ddHifi ones are great. The SQ won't be impacted. Be careful with cheap (Ali) ones with cables - I've had bad luck with a few that looked good but had internal/wiring issues. Fiio also has a good one with a braided cable.

For a really compacted setup, I'll recommend the 4.4-to-2.5 adapter by ddHiFi. For use with BT adapter however, I tend to prefer a cable style adapter sometime.

I thought the ddHifi adapters measured bad - you measured high output impedance on some of them. Maybe not all or have they improved with new models?

I am talking about this, are we on the same thing? I don't recall measure any of ddHiFi's adapter before.

p/s: Just tried to measure it via my BK Precision BK2712 multimeter, the pins in the adapter are averaging 0.03~0.05 ohm.

Thank you for the recommendation.
Is this the correct adapter (4.4 to 2.5)?

Just want to confirm if it’s recommended and isn’t measured badly, in case you happen to know. @ClieOS
That in your link is the new version with the metal housing. Mine are mostly the original version with transparent housing. I don't see why the new one will be worst or better than the new one as long as the internal is sufficiently similar.

Are 2.5mm cables reliable? I ordered one, didn't know you could buy a 4.4mm to 2.5mm adapter. I didn't have any 4.4mm cables though, just went with 2.5mm.
Treat it with care and I don't see why it won't last. I have been using 2.5mm cable for almost a decade now and none of them fails me.

Any recommendations for decent cable adapters? I have some of ddhifi's adapters, but it didn't seem like they carried a cable adapter for 4.4 -> 2.5.
Do you mean 4.4 M to 2.5 F or 4.4 F to 2.5 M DD makes a really good compact 4.4 M to 2.5 F
For the other, I had Xinhs make me one and they now sell them.
