Can highly recommend the Fiio 2.5mm short balanced cable. Beautifully made and sounds as good as any other balanced cable I've had including 4.4mm Sony Kimber ( a £180 cable vs £30 cable).
Balanced sounds noticeable better than SE. I also have the Fiio short 3.5mm cable but this is better throughout.
With LDAC set to sound quality pref. 990kbps you really arn't missing anything with the BTR5 balanced.
My Sony A105 wired or Dragonfly Cobalt have different signatures but can't really say one is better than the other except DFC still best for MQA tracks (Tidal) and drives demanding headphones.
I've previously had Fiio X5III and M11 but I'm enjoying this more than wired out of those.
Significantly better than BTR3 and also has the edge on the EarStudio too.
Dead silent, no hiss with my SE846's via SE or balanced.
Not really tried it as a wired DAC as I have my DFC.
Volume balanced low gain with SE846's only 22/60 so this should drive most headphones.
