GoldNote PA-1175 MKII Amplifier

Gold Note PA-1175 MKII – powerful stereo/mono power amplifier for demanding hi-fi systems

The Gold Note PA-1175 MKII is a high-quality stereo/mono power amplifier that combines high power output with precise control and superb musical reproduction. Its sophisticated Class AB circuitry, high current delivery capability, and flexible adjustment options make it a powerful amplifier for demanding loudspeakers and high-end systems.

At its core is a Class AB amplifier design with four selected transistor pairs per channel. This circuitry is supported by Gold Note's proprietary optical bias system, which ensures stable operation of the output stage. Together with the high-performance constant current generator, this results in ample power reserves combined with low distortion and controlled signal processing.

With 2 x 175 watts into 8 ohms in stereo mode, the PA-1175 MKII offers ample power for a wide variety of loudspeakers. If even more power is required, the amplifier can be switched to mono operation, delivering up to 350 watts into 8 ohms. This allows the amplifier to be flexibly adapted to various system configurations and used even in particularly demanding setups.

A particular strength of the Gold Note PA-1175 MKII is its adjustable damping factor. With two settings, 25 and 250, the amplifier can be precisely matched to the connected speakers. This adjustment allows for precise control of the speaker drivers and helps to optimally tailor the interaction between the amplifier and speakers to the specific system.

Even at high volume levels, playback remains stable and controlled. Dynamic impulses are reproduced with high precision, while complex musical structures are preserved clearly. The high current delivery capability supports confident control, especially with loudspeakers that have corresponding power requirements.

Sonically, the PA-1175 MKII delivers a powerful yet balanced sound. In the bass range, the amplifier operates with tightness and definition. Low frequencies possess substance and energy while remaining cleanly contoured. This ensures that even complex bass passages retain their clarity.

The midrange is stable and credible. Voices are reproduced with presence and nuance, while instruments retain their characteristic timbres. At the same time, the spatial arrangement of the musical performance remains comprehensible.

The treble range is refined and open. Details are precisely rendered without becoming unpleasantly prominent. The PA-1175 MKII thus combines high resolution with a balanced tuning that remains pleasant even during extended listening sessions.

The connection options include both balanced XLR and unbalanced RCA inputs. High-quality speaker terminals ensure a secure connection to the connected speakers. This allows the power amplifier to be easily integrated into a wide variety of analog hi-fi systems.

The modular design offers additional flexibility. The PA-1175 MKII can be expanded with an external power supply such as the PSU-1250 or PSU-1000 to further optimize power delivery. A tube output stage, either the TUBE-1012 or TUBE-1006, is also available as an expansion option, opening up additional possibilities for fine-tuning the system's sound.

The brushed aluminum housing underscores the high-quality design of the power amplifier. Measuring 430 mm wide, 135 mm high, and 375 mm deep, the PA-1175 MKII integrates seamlessly into both classic hi-fi systems and extensive high-end setups. It is available in black, silver, and gold finishes.

The Gold Note PA-1175 MKII is therefore a highly recommended, versatile, and powerful amplifier for listeners who value high control, dynamic reserves, and flexible adjustment options. The combination of stereo/mono operation, selectable damping factor, high-performance Class AB technology, and modular expandability makes it a compelling amplifier solution for demanding loudspeakers.
