HTA-2500B dual-mono 2 x 200W design utilizes 2 high-performance 12AX7-T PSVANE Treasure Mark II vacuum tubes in the preamp section serving as a buffer amplifier and 6 pairs of high-power Sanken transistors (2SC4468/2SA1695) in the output.
The HTA-2500B 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.
2 toroidal transformers with total output of 1200W (600W per channel) provide 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 very demanding and powerful speakers.
Audiophile grade ELNA capacitors (2 x 80V/10000uF for each channel) ensure stable playback improving music tone and sound field depth.
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.
Analog inputs with high-end solid machined brass RCA sockets can accommodate up to 2 stereo devices.
You can connect a range of digital devices via optical and coaxial inputs and a built-in high-resolution 24bit / 192kHz DAC (based on Wolfson WM8805 and Cirrus Logic CS4344 circuits) will always provide the best sound performance.
The HTA-2500B 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-2500B with a high-end headphone preamplifier.
A preamplifier output is dedicated for an optional external power amplifier or powered subwoofer and speakers.
The HTA-2500B 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-2500B is a splendid mixture of analog tube sound, power, precision, purity and multidimensional soundstage imaging!
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.
