Talk about tech
Beneath the extruded aircraft-grade aluminium chassis is serious hardcore technology:
- 60W high performance adaptive multi-mode controller, optimized for high efficiency, low standby power, and audio noise free design
- Frequency shuffling technique to achieve excellent EMI performance
- 400% increase in power supply capacitance for the adaptive multi-mode controller
- Oversized Power MOSFET
- Low-leakage transformer
- RF designed PCB
Elite design & specs
The iPower Elite has:
- <1uV noise floor
- Special circuit design for whisper-quiet noise floor using cherry-picked components
- Latest Active Noise Cancellation 2
- Full unibody Aluminium chassis with heatsink built-in
Powering flagships.
Expensive equipment typically ship with generic power supplies. This is like putting supermarket fuel in a Ferrari. It deserves the best but isn’t getting it.
The generic SMPS power supply (PS) is very noisy. Many upgraded audiophile linear PS are better, but still have huge noise at the rectification frequencies and at multiples 50Hz, 100Hz, 150Hz (or 60, 120, 180 for 60Hz countries) etc.
The iPower Elite was designed to deliver the smooth and silent power. It gives your streamer/DAC/amplifier all the silent, clean power of a battery with none of the hassle.
Tom Evans who makes very nice phono stages made the following astute comment:
A rumble filter simply adds to the bass cut making your already “cut” records sound bass light. Plus, it “time-steps” the bass in relation to the higher frequencies (where our hearing is most sensitive) so much so it can confuse the ear into believing the bass is playing out of tempo.
iFi solution:
Since the very first iPHONO launched in 2012, we have used our own in-house ‘Subsonic Filter’. It made it into the iPHONO2 and the iPHONO3 and now, the ZEN Phono which is the very first time this filter is seen in such an affordable price level.
As there is only minimal vertical modulation remaining at very low frequencies with an an actual cut LP that is playable, we know that “vertical modulation” at low frequencies must be warp.
So we designed a filter to take advantage of this.
This is not artificial but real knowledge. By understanding fully how LPs are cut and replayed, it is possible to filter record warp strongly without at the same time attenuating low bass or adding group delay.
