AmplifiersFiiO EA13 Class A Push-Pull Tube Integrated Amp — EL34 x4, 28W/ch, VU Meters, Headphone Out
FiiO EA13 — the K-series brand you know from the FiiO K11 / K11 R2R / K13 R2R DAC line goes big: a real Class A push-pull tube integrated amplifier with four EL34 vacuum tubes, 28 W/channel into 4-8 Ω, 4 RCA inputs, dedicated headphone output, and dual analog VU meters. This is a proper 18 kg tube amp with 400V+ B+ rail, not a hybrid or “tube preamp with Class D power stage” gimmick. Under $800 for a real EL34 push-pull integrated — that price point used to start at $1,500+ from PrimaLuna or Willsenton. Drives high-efficiency dynamic speakers (Klipsch Heritage, Zu Audio, high-sensitivity Wharfedale) plus most 88+ dB bookshelves with tube warmth and dynamics tube fans buy tubes to hear.

FiiO EH11 Retro On-Ear Bluetooth Headphones
Featured in our review: FiiO EH11 Review: LDAC Hi-Res Retro Headphones That Punch Way Above Their Price
FiiO EH11 — LDAC hi-res Bluetooth on-ear retro headphones under $130 with real 990 kbps LDAC codec for TIDAL / Qobuz / Apple Music hi-res streaming on Android (SBC + AAC fallback for iPhone). 40 mm dynamic drivers with warm-forward tuning that suits vocals, classic rock, and long listening sessions without fatigue. ~40 hours battery life, USB-C fast charging (10-min top-up delivers several hours of playback), 3.5 mm cable included for passive wired mode. Foldable retro form with included travel case fits in a backpack pocket; ~8.5 oz weight keeps them comfortable for all-day wear. FiiO build quality — metal accents, cushioned pads, real hinges.

FiiO K11 Desktop DAC and Headphone Amp — 1400 mW Balanced Output
FiiO K11 — entry-level FiiO desktop DAC and headphone amplifier with a punchy 1400 mW balanced headphone output and full digital input suite (USB, coaxial, optical, RCA line-in). The mainstream K11 (not the newer R2R variant) uses proven delta-sigma DAC circuitry for clean, resolving output that measures well and drives most headphones — 32 ohm IEMs to 300 ohm Sennheisers — to reference volume with headroom. Balanced 4.4 mm and single-ended 6.35 mm headphone outputs; RCA line-out doubles as a preamp for feeding a power amp. USB DAC handles PCM up to 32-bit / 384 kHz. Metal chassis, weighted volume knob, gain switch for sensitive vs demanding loads. For anyone who wants proven FiiO build quality and reliable performance without stretching budget for R2R ladder DAC circuitry — the K11 is FiiO desktop DAC/amp done right at entry level.

FiiO K11 R2R Desktop DAC and Headphone Amp — Discrete R2R Ladder Under $200
FiiO K11 R2R — the cheapest way into true discrete R2R ladder DAC sound. Uses a hand-picked 24-bit resistor-ladder DAC circuit (physically different from the delta-sigma chips in the base K11 and every Topping/SMSL competitor) for the warmer, more analog top-end R2R is famous for — without the $1,000+ price tag. Full digital input suite: USB-C, coaxial, optical, plus Bluetooth 5.1 with LDAC. Balanced 4.4 mm + single-ended 6.35 mm headphone outputs, 1400 mW into 32 Ω balanced — same power spec as base K11 but with R2R signature sound. Drives 32 Ω IEMs through 300 Ω Sennheiser dynamics with headroom to spare. Machined metal chassis, weighted knob, front OLED. Under $200 on Amazon is R2R value that did not exist two years ago.

FiiO K13 R2R Desktop DAC and Headphone Amp — Discrete R2R Ladder
FiiO K13 R2R — flagship discrete R2R ladder DAC and headphone amp of FiiO K-series. Uses a fully discrete 24-bit R2R ladder DAC circuit (physically different topology than the delta-sigma DACs found in most sub-$500 units) for a warmer, more analog top-end that many listeners prefer for long sessions, vocal-forward music, or hot recordings. Full digital input suite: USB (PCM/DSD), coaxial and optical S/PDIF, plus Bluetooth 5.1 with LDAC codec. Balanced XLR + 4.4 mm + single-ended 6.35 mm headphone outputs — full balanced signal path from DAC through amp to jack reduces channel crosstalk. Drives cleanly from 32 ohm IEMs to 300 ohm Sennheiser HD 800S with high-gain headroom. Metal chassis, weighted knob, MQA rendering support over USB (Roon / TIDAL). Serious desktop chain territory at K-series pricing. Live price on Amazon below.
