MoFi MasterPhono Phono Stage

Description

The MoFi MasterPhono offers listeners ideal optimisation with any cartridge as well as unparalleled flexibility, dead-quiet operation, and remote-controllable ease. Equipped with rare features such as passive RIAA equalization and two input topologies – one voltage type and one current-source type – MasterPhono also benefits from a discrete, balanced, wide-bandwidth, all-FET input and output stage; fully regulated and shielded internal power supply with dedicated left and right channels; and programmable relay-controlled loading and gain settings. A thick aluminium front panel frames a pair of meters that provide VU information as well as calibration points for cartridge setup.

Features:

MM/MC
Both standard signal input (“Voltage Input”) via RCA & XLR and “Current input” for use with low source-impedance phono cartridges, via RCA or XLR, utilizing “Trans-impedance dynamic loading”.
Dual-chassis construction that isolates power supply and audio circuits, featuring a separately isolated chassis and signal grounding post for the lowest overall system noise.
4 switchable gain settings of 40db, 50db, 60db and 70db.
10 switchable impedance loading adjustments, including a “Custom” via RCA plug on rear panel.
Fully discrete circuitry from input to output including fully balanced, DC coupled and servo controlled circuit from the high pass filter to the output jacks.
Passive RIAA exclusively using stringent parts selection; NOS polystyrene and polypropylene film/foil capacitors with better than 1% precision, as well as all critical resistors with tolerances 0.1% or 0.5% for precise filtering and voltages.
Cascaded voltage regulation stages to help achieve the lowest possible noise floor.
Remote control operation for input selection, gain adjustment, mute, mono operation, meter operation and subsonic filter.
Left and Right meters for output monitoring and calibration purposes.
Extreme RIAA accuracy of ±0.05db and frequency response of 10Hz–50KHz ±0.20db.
Maximum S/N Ratio (A-weighted) of 93dB for MM cartridges and 85dB for MC cartridges
Dimensions (W x H x D) mm: 432 x 89 x 400
Weight kg: 6.8

Built to accommodate a very wide range of pick-ups from high output MMs to low output MCs, MoFi’s MasterPhono phonostage is masterfully efficient in drawing the best performance from vinyl replay systems, as Adam Smith discovers in the December 23 edition of Hi Fi News. He says: “thanks to its various balanced/SE inputs and outputs, excellent range of adjustments and some novel new features, MoFi’s smart-looking MasterPhono is a pleasure to use. More importantly it’s a superlative performer, able to deliver all the detail, punch and musical emotion of your vinyl collection. The £6k demanded isn’t exactly pocket change, but if you have the budget, then an audition is mandatory.”
