Best praise vs top criticism for FiiO K5 Pro

Best Praise

“It's quite strange that they tell you it has to do with impedance, because the FiiO K5 Pro has a very low (2.2ohm) impedance output. It should work perfectly on paper.”

Top Criticism

+44 pts

“Yeah, I'd be curious to know what source OP is using. There was a guy here recently with a Fiio K5 Pro, I think, that was frying his right side drivers. Coincidentally, my dad also has a K5 Pro and his Audio Technica right side driver gave out recently.”
