BTR5 vs BTR7 vs other alternative amp
I recently got my BTR5 out and have been loving using wired headphones with my phone again. I was wondering if any upgrade would be worth it in everyone's eyes. I usually run earbuds with it but have some harder to run headphones I'd like to be able to use as well. I was thinking of holding onto my current BTR5 until a friend's birthday comes up and giving it to them once I get my replacement.
Also, in case I don't upgrade I still would like to give them a bluetooth amp since I know they'd be into it. Any recommendations for good cheap ones are also plenty welcome! I haven't shopped for audio equipment much in years so I'm fairly out of the loop on what the scene is like now (last thing I remember eyeing was the FiiO K9 Pro right after a factory caught fire and the ESS became the only version you could buy).
