HTA-700B v.3-USB

HTA-700B v.3-USB is the latest edition of our highly-rewarded and extremely popular mid-size hybrid integrated amplifier.

It utilizes 2 x 12AU7 Shuguang vacuum tubes in the preamp section serving as a buffer amplifier and a pair of TDA7296 transistors  in the output.

The HTA-700B v.3-USB 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.

The revised 150W toroidal 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.

To provide the best clarity of sound the HTA-700B v.3-USB utilizes audiophile-grade Wima capacitors which used on the input to and output from the tubes as well as for the tone regulators.

Audiophile grade Japanese ALPS volume potentiometer provides 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.

The high-end class, gold-plated speaker terminals offer almost lossless audio signal transmission to speakers.

Beside two analog sources you can connect a range of  digital devices via USB or optical inputs and a built-in high-resolution 24bit / 192kHz DAC (based on SA9123 and AK4430 circuits) will always provide the best sound performance.


The HTA-700B v.3-USB is also an ideal companion for mobile devices – stream music from smartphones, tablets or computers compatible with Bluetooth®.

For those who prefer discrete listening we equipped the HTA-700B v.3-USB with a high-end headphone preamplifier.

A preamplifier output is dedicated for an optional external power amplifier or powered subwoofer and speakers.

The HTA-700B v.3-USB offers additional options for easy upgrading the sound quality:
- Removable IEC power cable gives you an option to upgrade your system with a premium audiophile power cable in any time;
- The tubes are installed in high-quality ceramic sockets and they can be very easily exchanged for new tubes of your choice.

The HTA-700B v.3-USB 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.
