Headphone Amp Comparison

Schiit Magni Heresy vs FiiO K5PRO

Schiit Magni Heresy

Magni Heresy raises the bar even higher for affordable headphone amps, with by far the highest output power in their price class–at least 200% higher than any competitor. At the same time, they provide the cleanest measured performance of any Magni, ever.

$99.00 MSRP

FiiO K5PRO

The K5PRO is a compact, desktop DAC/headphone amp combo by FiiO. It features the leading AK4493 DAC chip with a wide variety of inputs and outputs to create a great value proposition.

Reviews

The Magni 3+ is also very competent amplifier and subjectively kept up with Heresy.

In that regard, and in the context of a budget product that is designed reasonably well, I am going to recommend the Fiio K5 Pro.
