SYNTHESIS is proud to introduce a stereo tube amplifier incorporating the exceptional the sonic performance.
The NYC 175i provides a minimum of 180 watts (360W per channel), power output from 8, KT88's in Ultra-Linear (UL) - push/pull operation.
The NYC 175i features a newly designed custom output transformer designed to achieve highly delicate and precise sound with extraordinary musicality from tubes, but with the authority of the best transistor amplifier.

FEATURES

- Aluminum Knobs
Two 45mm CNC machined control knobs with integral soft light and laser etched indication segments.

- DC Powered tube heater
All tubes, except KT88, have DC stabilized heater circuits to reduce hum noise to a near in-audible minimum.

- Output transformer
The Output transformer uses a double C-core Hi-Grade Iron-Silicon for superb frequency reproduction and bandwidth. With this newly designed custom output transformer unique to the NYC175i we are able to achieving highly delicate and precise sound reproduction faithful to the original recording.

- Mechanical chassis construction
The power supply and output transformers are held by an extremely rigid “H” structure that keeps the unit free from unwanted vibrations which further helps reduce unwanted noise to the tubes.

- Remote control
A superb wooden handmade case with soft button design, perfectly matching the aesthetics for the “Metropolis” series.

- Feet
Four CNC machined aluminum feet with an insert of natural rubber. The depth and form of these rubber feet is calculated to minimize the vibration of the amplifier in isolation from its surroundings.

- Fan
A 120mm fan provides a speed between 500 to 700 rpm which is controlled via micro. This ULN (Ultra-Low-Noise) unit is tailor made for the serious enthusiast who demands super-slow running speeds and the utmost silence of operation.
- Bias control
The factory set fine bias control is microprocessor controlled to maintain the optimum settings. If required this can be adjusted without the use of an external voltmeter by use of an internally fitted display device.

- Dual mono Circuitry
A completely dual mono design minimizes the crosstalk across channels. Power transformers use hi-grade iron silicon M0 and separate supplies with hi-grade selected capacitors to produce extremely low ripple levels. Independent to the mains transformer, each channel has a separate power supply guaranteeing a large reservoir of energy to meet the demands of the amplifier circuit and to maintain excellent interference immunity between channels.

- Binding posts
Gold plated professional binding posts for a continued oxidization free connection further improve sound refinement.

- Socket
Gold plated ceramic sockets for a continued oxidization free connection further improve sound refinement.

- Components
Components for the NYC 100i have been selected with great care throughout. Only the best available components are considered and all must undergo an exhaustive analysis of their sonic influence prior to final selection.

- Selected tubes
All tubes used are selected after 2 stage warm up. A fully computer monitored machine controls the process and at the end of this, selects the perfect tubes which are matched for a perfect balance
