HTA-2000B v.2


Description

HTA-2000B v.2 is a 150W high-end hybrid integrated amplifier utilizing a 12AX7 tube preamp section with a cathode type amp circuit and a 12AU7 SRPP stage serving as a buffer amplifier.
This solution ensures a very warm, linear and lifelike sound with high dynamic presentation at the same time.

High-performance tubes and precise high voltage transistor hybrid power supply provide voltage stability and very low AC ripple current. It reflects in a more natural and fresh sound with deep multidimensional soundstage.

High-power transistors utilized in the 0dB current amplification circuit reveal more content of the music, giving extra pure energy and dynamics to drive even very demanding and powerful speakers.

The tube circuit cross-connected with audiophile grade MKP capacitors ensures 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 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 3 stereo devices including a turntable (both MM and MC cartridges) so you can enjoy music from your favorite vinyl records.

You can connect a range of  digital devices and a built-in premium high-resolution 32bit / 384kHz DAC will always provide the best sound performance. A USB DAC input is a perfect choice for playing digital music from computers, servers or compatible smartphones.


The HTA-2000B v.2 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-2000B v.2 with a high-end headphone preamplifier.

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

The HTA-2000B v.2 is a splendid mixture of analog tube sound, power, precision, purity and multidimensional soundstage imaging!

Technology



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.
