Which is the better buy? Side-by-side on rating, price, strengths, and watch-outs — with the published ratings we averaged to get there.

Topping DX3 Pro+ comes out ahead by a narrow margin (4.4 vs 4.5). The gap is mostly about desktop listeners who want measurements-grade ESS DAC plus phone Bluetooth in one box — read the strengths below before deciding.

Ranked #4 in Best DAC Amp Combos Under $300

FiiO K5 Pro ESS

4.4

$170

The K5 Pro ESS is the cheapest ESS DAC pick. ES9038Pro in this price class is unusually generous — most $170 DACs use lower-tier chips. Best for users who want strong measurements without paying for balanced output or Bluetooth.

Strengths

— Flagship ES9038Pro DAC chip in a $170 chassis — uncommon at this price
— 1.5W into 32Ω from the 6.35mm single-ended output
— Solid metal chassis, premium volume knob — feels more expensive than it is

Watch-outs

— No balanced output — single-ended only
— No Bluetooth like the Topping DX3 Pro+
— Older design — FiiO updated branding has moved to the K7 / K9 family

Higher ratedRanked #3 in Best DAC Amp Combos Under $300

Topping DX3 Pro+

4.5

$179

The DX3 Pro+ is the measurements-and-features pick. ESS ES9038Q2M plus Bluetooth LDAC plus a remote control at $179 is the most-feature-per-dollar combo here. Best for desk listeners who alternate between wired headphones and phone Bluetooth.

Strengths

— ES9038Q2M DAC chip — class-leading measurements at this price

Watch-outs

— Less power than the FiiO K7 — adequate for most headphones, tight on planars
