  • The Long Story


    Ultra-wide gain from 36dB up to 72dB

    The iPhono 2 allows you to optimally accommodate any cartridge in your system, to get the best out of your Vinyls. The maximum gain is now of 72dB, this means it can easily handle low output MC Cartridges. There is no need for the use of audio degrading step-up transformers. 
    The original iPhono was already competing with other phono stages, multiple times its own price, with its dynamic range of 90dB. The iPhono 2 has gone even further and has a dynamic range of 106dB, now not just competing, but bettering most phono stages multiple times its price. 





    Most accurate range of EQ curves

    The newly designed RIAA Equalisation circuit guarantees a +/- 0.2dB accuracy of the RIAA EQ from 20Hz – 20kHz, a reference class performance, period.

    The iPhono 2 is also a perfect match for older non-RIAA LPs too. The iPhono 2 retains the very popular 6 different Stereo EQ curves found in the original iPhono. So one will never have to put up with sub-optimal sound quality because of being unable to select the correct EQ curve ever again.


    Latest AMR trickle-down; Class A, TubeState®

    In the iPhono2, the Class A TubeState® has been further refined. There is an all-new Burr-Brown Soundplus® J-FET type amplifier at the heart of the new Class A, J-FET/BJT output buffer.

    This new circuit significantly reduces the loading seen by the main amplification circuit; which improves the circuit inherent linearity while allowing it to drive even punishing 600 ohm studio inputs with impunity.

    The power supply filtering has been increased 5X in value. The iPhono2 noise performance was further optimised to achieve a noise levels that approach what is feasible at room temperature. To achieve lower noise, cooling the circuit in liquid nitrogen would be needed. The super-silent noise floor of the iPHONO2 is quite remarkable. It defies its price class to challenge money-no-object phono stages.

    The litmus test of any good phono stage design is that it is able to amplify the signal but not the noise. Thus, the best test for any phono stage is to turn up the system as loud as possible and then lift the needle. Why? As it’s a great test for noise, or lack of it. It allows you to test cleanliness of the signal it outputs. Hence, we recommend this to our customers as we are certain the iPhono 2 will pass with flying colours.

    The Signal-to-Noise ratio of the iPhono2 is 3dB quieter on MC and 10 dB quieter on MM than the original iPhono.

    More than ever, listening to vinyl, one can hear ‘into’ the recording itself with the blackest of backgrounds and every nuance, inflection is picked up by the system.





    DC-Infinity circuit is light-years ahead

    To guarantee an output free from DC, a ‘textbook’ high-end Phono Preamplifier* usual has up to 5 coupling capacitors from MC cartridge to output in addition to DC servos, all of which cause signal quality degradation. The original iPhono had only 2 coupling capacitors and no DC servo. In the iPhono2, with the all-new Direct-Drive Servoless ‘DC Infinity’ circuit, it has no capacitor AND no DC-Servo; so it adds zero noise nor distortion into the audio signal path.

    *The example stated is from a textbook on audio circuit design, called "Small Signal Audio Design" by Douglas Self.


    Reference class parts quality

    The iPhono2 employed even more Japan TDK C0G type capacitors. These are complimented by Japan Panasonic ECPU Film Capacitors explicitly designed for audio use with extremely low distortion (<0.00001% @ 1V/10kHz). iPhono2 also uses many more Vishay MELF type thin film resistors compared to the original. Goes to show that iFi puts thought into all of its products and strives to serve the best quality at unbeatable prices!
