Class A TubeState
The ‘magic’ of tubes from solid-state.

iFi's Class A TubeState® technology is the result of nearly four decades of research of iFi's Chief Designer, Thorsten Loesch, on tube and transistor gear.

The key is not to add distortion, but to avoid certain types of distortion. Once it is understood that specific distortions are endemic to solid-state circuitry and are pernicious with respect to subjective sound quality, iFi eliminates these from solid-state circuitry, without adding on tube-like distortion and noise.

Switchable Phono Equalization
Precisely match up LP equalisation!

Listen to vinyl recordings in the original and correct way. When so much is invested in an audio system, to leave out the final few percent of correctly matching the equalisation to the LP is almost sacrilege.

Direct Drive Servoless
Direct Drive Servoless® is an important element of the audiophile experience, which is not visible in measurements but is quite audible.

Unlike a standard phono stage design, the iPhono3 Black Label continues the special design tradition of being direct coupled (i.e. no coupling capacitor) from cartridge to output and it does so without requiring a conventional DC servo.

DC infinity
In the 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 DC-Infinity circuit is that it only changes the gain below approx. 0.01Hz, while leaving the AC behaviour of the circuit at higher frequencies unchanged, injecting neither noise nor distortion into the audio signal.

Any noise and distortion of the DC-Infinity circuit happens at the same signal level as the output signal and is by design around 100 times less than the noise and distortion of the actual amplifier circuit, so compared to the actual phono stage noise and distortion it effectively disappears.
