I would like share my review for PAI MR2 


My friend just dropped at my house iphone 6s Rose Gold from USA
Now i can use Centrance HiFi Skyn with my own Iphone 6 S Rose Gold

But still below my Phone 5 s

micro iPhono2
Only everything has been improved

Southport, UK – 25th April 2016
The best just made the quantum leap

The original iPhono was the ‘benchmark’ phono stage <US$1,000. Only retaining the same design philosophy, we went back to the beginning and designed a ground-up, all-new iPhono2. The design, circuitry and parts are all far-reaching:
1. Ultra-wide gain range – 36dB to astonishing 72dB; suits any cartridge.
2. Whisper quiet – SNR of >86dB, an impressive 10dB quieter than the original.
3. Latest AMR trickle-down technology: revised Class A, TubeState® circuit for unrivalled linearity.
4. DirectDrive® Servo-less ‘DC infinity’ circuit. No capacitor AND no DC-Servo means zero added
noise and distortion, there is no purer audio signal path.
The sonic performance of the iPHONO2 when partnered with any cartridge from the Shure V-15 through to the Koetsu Coralstone is something to behold.
• Ultra-wide gain from 36dB up to 72dB
• 6 precision stereo EQ curves (±0.2dB)
• Latest AMR trickle-down technology: revised Class A, TubeState® circuitry
• DC-Infinity circuit, DirectDrive® Servo-less circuit
• Reference class parts quality from Elna Silmic to Silver Mica capacitors
• iPower (15V) included, ‘quieter than battery’ power supply
