Taga Harmony TTA-1000BT Tube Integrated Amplifier

The Taga Harmony TTA-1000BT is a pure Class A stereo integrated amplifier using vacuum tubes. This device combines the warmth and natural sound typical of tube amplifiers with modern performance and connectivity.

Design and Components

The TTA-1000BT is a fully tube-operated stereo integrated amplifier in pure Class A. Its push-pull output stage uses the legendary KT88 power tube, known for its robust and dynamic character. Each channel is equipped with two KT88s, delivering 2 x 60 W at 8 ohms. The preamplifier stage employs two 6SN7 tubes and one 12AX7 (ECC83) tube in a long-tail phase inverter configuration.

Taga has paid particular attention to the choice of components. The KT88, 6SN7, and 12AX7 tubes come from the Classic series by Psvane Audiophonics, a reference in the field. They are mounted on ceramic sockets with gold-plated contacts. High-end coupling capacitors are used: Evox at the input, Wima for the connection with the output stage, and Rubycon in the amplifier stage. The motorized volume potentiometer is an ALPS model.

Each channel has its own rectifier and filtering circuit in the power supply for better separation. The wide-band toroidal output transformers ensure stability and dynamics. The bias adjustment of the output tubes is done manually. The overall construction is very robust, with a thick steel sheet chassis and an 8 mm thick solid aluminum front panel.

Features and Connectivity

In terms of connectivity, the TTA-1000BT has two stereo RCA line inputs (CD and auxiliary), as well as a switchable MM/MC RCA phono input for turntables. An RCA preamplified output allows connection to a power amplifier or an active subwoofer. The speaker terminals are made of solid brass with gold plating and accept large gauge cables. A Bluetooth 4.0 receiver is integrated for audio streaming from a smartphone or tablet.

The TTA-1000BT comes with a brushed aluminum remote control that provides access to all essential functions. A tube protection grille is factory-installed. The detachable IEC power cord allows for potential upgrades. Note that the amplifier heats up significantly during operation, which is normal for a Class A tube model.

Sound Performance

The Taga Harmony TTA-1000BT offers remarkable musical performance. Its 60 W per channel in pure Class A provides a comfortable power reserve, capable of driving most speakers, including medium-efficiency floorstanders. The sound delivered is ample, robust, and very dynamic, with the warmth and smoothness typical of a tube amplifier.

The reproduction is extremely lively and realistic, with a beautiful harmonic richness. The soundstage is wide and deep, with an excellent sense of depth. The timbres are very accurate, with mids of rare beauty. The highs are fine and delicate, without aggressiveness. The bass is present, fast, and articulated. Overall, this amplifier provides immediate and lasting listening pleasure across all musical genres.
