Pure Class‑A Integrated Amplifier

The XA6800R (II) is one of Xindak’s most well‑known and long‑running integrated amplifiers. It is a fully solid‑state, pure Class‑A design, developed as a major evolution of the original XA6800R, with revised internals, improved thermal management, and added digital connectivity. [xindak.com]

Design Philosophy

  • Pure Class‑A operation
  • Focus on musical flow, tonal richness, and stability
  • Built around symmetrical circuitry and high‑current power supply
  • Designed to combine Class‑A smoothness with solid‑state control [xindak.com], [audioemotion.co.uk]

Xindak explicitly positions the XA6800R (II) as a no‑compromise Class‑A amplifier intended to be the core of a high‑quality stereo system.

Circuit & Construction

Amplifier Topology

  • Pure Class‑A output stage
  • Dual‑mono, fully symmetrical internal layout
  • Selected and matched bipolar output transistors
  • Designed for continuous Class‑A biasing [audioemotion.co.uk], [polarisaudio.it]

Power Supply

  • R‑Core (R‑type) transformer
  • Central transformer placement for mechanical balance
  • Large capacitor bank (≈40,000 µF reported by reviewers)
    [polarisaudio.it], [audiomuzofans.pl]

Thermal Management

  • Copper heat‑conduction bridges connect output devices to external aluminium heatsinks
  • Passive cooling only
  • Designed to maintain stable operating temperature despite Class‑A bias [xindak.com], [polarisaudio.it]

Inputs & Connectivity

  • 4 × RCA line‑level inputs
  • 1 × USB input for direct computer connection
  • USB input uses an internal DAC (Burr‑Brown PCM2704, 16‑bit / 48 kHz), as stated in reviews

⚠️ No phono stage is specified by any source.

Front Panel & Operation

  • Dual VU meters with blue backlight
  • Motorized volume control
  • Input selector
  • Power switch on front panel
  • Supplied with full‑function aluminium remote control (dealer‑stated)
