180W Dual Mono Integrated Amplifier
SYNTHESIS is proud to introduce a stereo tube amplifier incorporating the exceptional the sonic performance.
The NYC 175i provides a minimum of 360 watts (180W per channel), power output from 8, KT88/6550'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.
- Aluminium Knobs
Two 45mm CNC machined control knobs with integral soft light and laser etched indication segments.
- DC Powered tube heater
All tubes, except KT88/6550, have DC stabilised 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.
Four CNC machined aluminium 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.
A 120mm fan provides a speed between 500 to 700 rpm which is controlled via the supplied adapter. 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 minimises 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 oxidisation free connection further improve sound refinement.
Gold plated ceramic sockets for a continued oxidisation free connection further improve sound refinement.
Components for the NYC 175i 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.
