It has enough power and inputs to be the center of a desk, not just an add-on. ## Why we picked it Best for: A fixed desk with high-impedance headphones, a console or a TV feeding it. 1.5W into 32 ohms with three-position gain, plus optical and coaxial inputs. This is the pick if your headphone is hard to drive. **What we like** - 1.5W into 32 ohms with enough voltage swing to control a 300-ohm headphone, not just make it loud - Three-position gain covers sensitive IEMs through demanding dynamics without landing between steps - Optical, coaxial, USB and RCA inputs let a console, a TV and a computer share one amplifier - RCA line output drives powered speakers from the same box, so it replaces a preamp too **Watch outs** - Mains powered with no battery and no Bluetooth, so it is a permanent desk fixture - Single-ended 6.35mm output only, so a balanced headphone cable is wasted on it - Runs warm and wants clear air around it, which rules out a closed cabinet - No EQ of any kind, so tone shaping has to happen on the source ## Specifications - Item Dimensions: 4.72 x 1.97 x 5.12 inches - Material Type: Metal - Brand Name: FiiO - Item Weight: 436 g - Item dimensions L x W x H: 4.72 x 1.97 x 5.12 inches ## Price history (tracked by Elan's Best) - Current: $179.99 (checked 2026-08-03) - Lowest we have recorded: $142.99 on 2026-07-13 - Highest we have recorded: $179.99 on 2026-08-03 - Our own weekly checks: 6 over 40 days, from 2026-06-24 to 2026-08-03 - Median of our checks: $148.49 - Plus 14 monthly points dated before 2026-06-24, bought from a commercial price-history API rather than checked by us, and excluded from the figures above ## Common questions ### Is the FiiO K5 Pro Headphone Amps Portable Desktop DAC and Amplifier 768K/32Bit and Native DSD512 for Home/PC 6.35mm Headphone Out/RCA Line-Out/Coaxial/Optical Inputs worth it?
