Gold Note
MAURIZIO ATERINI - FOUNDER - From a very young age the passion for music and its instruments of reproduction have marked my life so much to condition every choice I made. I desired to be able to offer the greater audience ideas and technical potentials with an all-Italian brand specialized in Hi-Fi created by a team with years of experience in the field. In 2012, with my wife Elena, my partner Alessio and a team of specialized technicians and engineers I founded GOLD NOTE, profiting from previous work experiences in the same industry. Together we created a High-End audio brand which since the start wanted to speak a simple but evocative language in order to bring the best of “Made in Italy” to the whole world. In my opinion, one of the greatest peculiarities of this brand is its “double glance”, our business vision which in some ways directed to the past, but at the same time to the future. On the outside, this approach is expressed by forms we give to our creations which prove a strong references to the artistic history of Tuscany though representing our point of view on the future of quality listening. The same thing is true on the inside of our products which are designed based on the cornerstone elements of the audiofile tradition but introducing new features and using components of information technology unknown to these kind of products until recently. The spirit of our audio equipment stems from the fusion of past and future. This means that we don’t see a contradiction in combining avant-garde technological innovations with a design that seeks ties with tradition. The Renaissance of our city Florence is a role model to be inspired by every day, a period of great technological innovation and new ideas, and this is the tradition we are interested in - it is our mission to reread it with deference and respect to obtain a direct connection with that innovative spirit of six centuries ago. Today Gold Note presents a line of unique, perfectly coherent and elegant products that allow you to set up an entire quality stereo system with turntables, electronics and loudspeakers. A philosophy that has allowed us to represent Italy, the most beautiful country in the world, as I have always dreamed of doing.

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.

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, doubling its already great power rate from 175W per channel @ 8ohm up to a considerably 350W 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 630VA 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.
