After 200 hours break in Campfire Trifecta sounds bright using iBasso and iFi headphone amps. With the supplied balanced cable, the Trifecta sounds better - less bright.
I’m confused — if the Trifectas sound better with the stock balanced cable then why not just use that, and what other cable are you using that makes them sound bright? C’mon man, help us help you here cause this is just confusing. I’m not familiar with your equipment, but I suppose it’s possible the much more expensive Trifecta is more resolving and may just be exposing shortcomings of your upstream gear. I don’t know, but if that’s possibly the case it’s better to address the source of the problem rather than trying to patch it up with a cable. Would help if you’d give more detail on exactly what components are in your system.
