  • Tube Amplifier — Dual 6J1 preamp stage adds smooth, natural warmth and detail; rated 35W×2 @4Ω / 25W×2 @8Ω to drive common bookshelf speakers, with discrete circuit, four 2200µF caps and a 90W transformer for clean power.
  • Bluetooth Receiver — Fast, stable wireless pairing from phones, tablets, and laptops; one-touch input switching and clear status indicator make hopping between wireless and wired sources effortless.
  • Optical/Coaxial — TV/console-friendly SPDIF inputs bypass noisy analog outs for clearer dialog and music; ideal for upgrading flat-panel audio without extra DACs or complicated wiring.
  • Flash-Drive Player — Direct playback from USB drives up to 128G; supports FLAC/APE/WAV and more so you can enjoy bit-perfect local files without a computer.
  • PRE-OUT 2.1 — Dedicated pre-out makes adding an active sub simple; blend low-end weight with your L/R speakers and fine-tune using independent bass/treble knobs for room-matched balance.
