Here is the revised version of Gold Note’s first stereo amplifier, which replaced the Demidoff Anniversary amplifier in 2015. Gold Note’s latest creation, again, features all the innovations that have always distinguished their designs, says their recent press release.

PA-1175 is a Stereo Power Amplifier which features 4 matched pairs of transistors per channel with a proprietary Gold Note BIAS constant current generator which enables high currents and high power rates with ultra-low distortion.

The power amplifier features a BTLtechnology [Bridge-Tied-Load] so the unit can be easily bridged to work as a mono amp doubling its large power rate from now 200watt (previously 175watt in the Mk1) per channel @ 8ohm up to a considerable 520watt (previously 350watt) per channel.

The flexibility of the power amplifier can be largely extended with the mono application for all kind of speakers that really require high  power. The latter is provided by a 640VA custom made toroidal audio transformer with original Ducati race bike silent blocks for insulation.

A small 6VA transformer powers all service functions outside the audio signal path.

PA-1175 also features a Damping Factor switch conveniently selectable from the front panel. Set up to 250 DF or 25 DF it allows an ideal match with any kind of speakers. At 250 DF it offers the control necessary for large and difficult speakers while at 25 DF acts as a low power tube amplifier, ideal to drive high-sensitivity or mini monitor speakers.

PA-1175 is built around a high mass steel chassis and thick aluminum panels to avoid RFI and EMI interference.

The panels are made of brushed aluminium available in black, silver or gold finish.

The increase in power, the new wiring and the replacement of some key components such as the power devices have made this amplifier the best amplifier ever made by Gold Note.

From the beginning of December 2018,PA-1175 MkII will be available worldwide through Gold Note dealers at a MSRP of 5.500€.
