Southport, UK – May 2020 iPhono3 Black Label micro series the Tech iFi audio iPhono3 Black Label Beauty and Beast iPhono3 Black Label over other phono stages • One of the quietest phono stages. Bar none. • Ultra-low distortion. High gain of 72dB en par with flagship phono stages. • Computer-matched high-gain bi-polar input transistors and more.
the Tech iPhono3 Black Label All new specifications • Dynamic range improved by 5dB to 108dB. 36-72dB gain. • 85dB A-weighted SNR is 3dB quieter (re 0.5mV/5mV per Stereophile standard). • The increase in the power-supply voltage of the external iPower X ultra-low noise adapter for iPhono3 Black Label to 15V allowed for greater undistorted signal levels for LPs like the legendary (and often unplayable) Telarc 1812. All-new hand-matched Burr-Brown Soundplus® J-FET type operational amplifier.
Southport, UK – May 2020 iPhono3 Black Label micro series the Tech It is packed throughout with TKD Japan made C0G type capacitors. Capacitors owning the C0G specification have lower thermal drift and distortion than Polystyrene capacitors. The iPhono3 Black Label uses them for the actual equalisation AND power supply bypass capacitors. ELNA Japan made Silmic Capacitors are used for the power supplies.
the Tech iPhono3 Black Label recording labels joined the bandwagon and adopted the RIAA standard. Right up to the fall of the Berlin Wall in 1989, many Eastern European recording labels (including Russian recording labels) were still, using their own CCIR equalisation. To further complicate matters, even after officially agreeing to implement the RIAA equalisation curve, many recording labels continued to use their proprietary equalisation, even well into the 1970’s.
Southport, UK – May 2020 iPhono3 Black Label micro series the Tech Sub-sonic filter The iPhono3 Black Label’s sub-sonic filter is well designed and implemented. Why is it needed? A warped track or record will cause a large signal output in the subsonic region, typically well below 20Hz. For example. A 33 1/3 RPM album with a single warped section can create a signal in the pickup at 0.55 Hz (33.3 RPM / 60 = 0.555 Hz). This is a signal that will cause significant cone movement, and is is very undesirable.
the Tech iPhono3 Black Label In iPhono3 Black Label the unique ‘DC-infinity’ circuit boosts the circuits DC gain to approach infinity (it is approximately 1 trillion one million times one million; 1012). Once the feedback loop is closed, this near infinite DC gain cancels all offset voltages to deliver a direct-coupled output with 0V DC offset. The key to the ‘DCInfinity’ circuit is that it only changes the gain below approx. 0.
Southport, UK – May 2020 iPhono3 Black Label micro series the Tech engineering journey by building his own kits at a young age. Thorsten continued exploration of the audiophile realm by repairing and refurbishing classic tube gear, HiFi tubes, guitar and bass amplifiers as well as pro-audio devices. His international fame was gained mostly through extensive publishing.
the Tech iPhono3 Black Label amps will also provide faster transient and broaden the spectrum of the dynamic range. Technical Specifications Freq.
