HTA-2000Bv.2 Hybrid Amplifier Bluetooth® 32bit/384kHz DAC

High-End Hybrid Power!


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!






A unique review with 3 independent opinions: one by the reviewer and two by private members of the Audiomuzofans Facebook group. 
The members are users of two vintage integrated amplifiers, which were the high-end in the 80's and 90's (and still remain high on the list). 
One is a dual-mono Pioneer A-77X amp with a serious tune-up and modifications and the other one is Sansui AUX-901.



"…Beginning from ZZ TOP and Dire Straits in rock and Gary Moore in jazz, we were able to find a "spark", dynamics, without such a characteristic problem for less "successful" amplifiers, namely losing of the details, and blurring of vocals. TAGA was melodious in smooth jazz and ballads what is characteristic for tubes and at the the same time it remained detailed and with an extensive scene, almost to be worthy of imitation. While listening to Gwyneth Herbert "Narrow My Man", we looked around as if by any chance the singer was not standing right in our listening room…


… I always thought that the Pioneer sounded with a tight and vivid bass until I heard the TAGA. For long time I haven't had such an amp which is able to master the lowest registers in such a way, at the same time improving its timbre to even better emphasize the nature of the instruments, that build up the low frequencies. The effect strongly desired in instrumental music or jazz…


My amplifier (Sansui AUX-901) sounds in a slightly warm analog way with lots of details. I could hear more bass with the TAGA amp on each of the songs like on a strong transistor and it was a well-controlled bass. The HTA-2000B v.2 amplifier is more musical but when it comes to the spaciousness of sound, depending on a music genre, one time the winner was Sansui and another time TAGA…

…It is ideally suited for the instrumental and acoustical music as well as for well-arranged pop or rock. Everyone who appreciates the separation of instruments and speed and dynamics will be delighted with a purchase of this device…"



Reference class sound


Tested together with the Diamond F-200 flagship speakers  by “STEREO I KOLOROWO underground” at the Audio Video Show in Warsaw during an unusual music session. 

A Canadian cellist Mr. Vincent Bélanger was playing cello live, performing tracks from the newest album Bélanger & Bisson "Conversations" (XLO 25th Anniversary Edition, Universal Music Canada - 2016) while TAGA Harmony high-end stereo system was reproducing Mrs. Anne Bisson vocals and other instruments from the album.



The TAGA Harmony set provided very euphonious, energetic and malleable sound with great stereo and superior space. There was an illusion of participating in a live concert. This phenomenon was reinforced by the dense and analytical sound of the Diamond F-200 speakers and the high physicality of the HTA-2000B amplifier, which dynamism seemed to have no limitations. At the time when Vincent Bélanger pulled out the fiddlestick and began to move it on the cello strings, it was hard to distinguish the sound played by the speakers from this being played live. The amazing thing. 
Vincent prepared about a 30 minute concert, played a variety of pieces from the "Conversations", he impressed us with different playing styles on the cello and flirted with the audience using his virtuosity. However, it was impossible to distinguish the real cello music from the background played by the speakers. This demonstrates very high values of the TAGA Harmony Diamond F-200 speakers, because the high-end is considered to be such a system, which plays genuinely "live".
