Taga Harmony HTA-25B Hybrid Integrated Stereo Amplifier
HTA-25B is a 25W / 4ohm high-fidelity but still affordable hybrid integrated amplifier utilizing two 6P1 and two 6N1 tubes in the preamp section and transistors at the output powered by an audiophile grade toroidal power transformer. This solution ensures a very warm, linear and lifelike sound with high dynamic presentation at the same time.
The high class, gold-plated speaker terminals offer almost lossless audio signal transmission to the speakers.
The HTA-25B offers a variety of different connections both wired and wireless:
-
2 analog inputs with gold-plated RCA sockets.
-
USB input to quickly and easily play music from USB flash drivers.
-
Bluetooth® to wirelessly stream music from smartphones, tablets or computers.
-
REC output for external recording device or powered speakers or subwoofer.
-
Headphones output for those who prefer discrete listening.
The removable IEC power cable gives an option to upgrade your system with a premium audiophile power cable in any time.
The HTA-25B combines the analog sound of tubes with the power of transistors to give the best sound at the price!
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.
