Questions & Answers

HTA-600B combines the best of both worlds - soft and analog-like sound character provided by tubes and adding to that high dynamics and power of transistors.


  • Bluetooth® - to wirelessly stream music from smartphones, tablets or computers.
  • Class A/B hybrid design utilizing two 6H3 vacuum tubes in the preamp section a pair of transistors in the output to ensure a very warm, linear and lifelike sound with high dynamic presentation.
  • Compact size and sleek aluminum front panel design suitable for most interiors.
  • 150W toroidal power transformer provides large amounts of clean power, high voltage stability and very
    low AC ripple current. This reflects in higher dynamics and extra pure energy and greater abilities to properly drive different range of speakers.
  • High grade capacitors (2 x 50V/3300uF) ensure stable playback improving music tone and sound field depth.
  • The audiophile grade ALPS volume potentiometer ensures minimal noises and channels crosstalk and has excellent operational feel and limits errors between the two channels.
  • Oversized aluminum heat sink system (independent heat sink for each channel) helps to disperse internal heat and allows for long term high power playback with limited distortions.
  • Headphone output for those who prefer discrete listening.
  • Digital Optical input - to connect a range of digital audio devices (CD/DVD/Blu-ray player, video game console etc.).
  • Preamplifier output - dedicated for an optional external power amplifier or powered subwoofer and speakers.
  • 2 analog inputs with gold-plated RCA sockets.
  • High-end, gold-plated speaker terminals accept raw speaker cables up to 10AWG and most popular types of connectors.
  • Treble/Bass sound regulations and Loudness function - to perfectly adjust the sound to your preferences.
  • Removable Schuko-IEC C13 power cable gives an option to upgrade the system with a premium audiophile power cable in any time.
  • Aluminum remote controller.

The HTA-600B is a splendid mixture of analog tube sound, power, precision, purity and multidimensional soundstage imaging!

Hybrid amplifier

What does it mean and why does TAGA Harmony use this approach?

Hybrid means a combination of two different techniques to create an amplifier in one device: the World of tubes and the World of transistors.

TAGA Harmony amplifiers use vacuum tubes in the preamp section and transistors in the power stage. This results in tube, soft and analog-like sound character and at the same time high dynamics and power provided by transistors, which is usually a weak point of pure tube designs.

The sound of TAGA Harmony hybrid amplifiers is not only silky and rich but also powerful and dynamic. In addition, hybrid amplifiers compared to pure tube amps have better abilities to properly drive different kind of speakers.

After being turned on a hybrid amplifier requires to warm up its tubes to reach its full sound capabilities – it usually takes from 5 to 15 minutes depending on model and room temperature.
