Here is Gold Note's first stereo amplifier, our latest creation features all the innovations that have always distinguished our designs: PA-1175 merges the knowledge of the acclaimed Demidoff single ended amplifiers with high power rate never reached before as well as new innovative technologies. Now available as the revised MKII version!

PA-1175 is our first stereo Power Amplifier: a new design that features 4 matched pair of transistors per channel with a proprietary Gold Note Optical BIAS and a constant current generator to achieve high-current and high-power rates with ultra low distortion.

Our proprietary and innovative Optical BIAS control the voltage reference of the unit: it features optical decoupling to overcome the inefficient and downgrading solutions of traditional electronics, optically analysing the audio signal while being completely separated from the audio signal path for the highest protection and unbeatable performance.

The BTL technology [Bridge-Tied-Load] allow the unit to be easily bridged in order to work as a mono amplifier, more than doubling its already great power rate from 200W per channel @ 8ohm up to 520W per channel.

The flexibility of PA-1175 and its performance can be pushed even further when used as a mono unit with speakers that really requires high power, massive energy and quality watts.

For PA-1175 we developed a custom 640VA toroidal transformer with a unique cut spiral nucleus: the refined mechanical process makes the nucleus completely stable, cancelling any mechanical vibration to guarantee a terrific effect and perfect insulation, further enhanced by the use of original Ducati silent blocks.
A secondary small 6VA transformer powers the auxiliary functions with dedicated circuits outside of the audio signal path.

PA-1175 is a unique power amplifier: it features an adjustable damping factor technology that you can easily select straight from the frontal panel.
Changing the Damping Factor to 250 or 25 will let you find the ideal match between PA-1175 and your speakers: use a 250DF to get the power and control necessary to drive large, difficult speakers or set it on 25DF to use it as a low power tube amplifier, perfect to drive high sensitivity speakers and smaller speakers.

To avoid any RFI and Emi potential issue, we have built PA-1175 starting with a massive solid steel chassis and adding thick aluminium panels.

The PA-1175 is tested with CD-1000 on HiFi NL, here a brief abstract in English:

"Now I realize how fast I became friends with the beautiful sound of the Gold Note CD-1000 and the PA-1175. Subtle but powerful, detailed but also silky soft, very spacious and stable. And full of character. A subtle but clear 'sound' has been developed for the good listener.
Add to that the very solid build quality and the fine Italian design and you have a set where you can enjoy music at a very high level"

English abstract from the article:

"this amplifier has very low distortion and excellent dynamic range indeed. I consider PA-1175 something new in the field of amplification after showing granite stability in performance regardless the time of the day or the many hours of operation. PA-1175 in two words is A FEAST of resolution and power with finesse, and inherently musical DNA, which doesn`t chooses the loudspeaker like other products, but adapts itself to play everything in a very easy and effective way. Bellissimo!"
