ZEN CAN
Each Panasonic ECPU capacitor features some 3,500 layers of
ultra-thin dielectrics less than 0.5
μ
m thickness. This gives
class-leading Equivalent Series Resistance (ESR), low impedance (other than at the
desired capacitance) as well as frequency stability and vanishingly low distortion. A
total of 6 pieces are used.
TDK C0G (Class 1 ceramic) capacitors offer high stability
and low losses for resonant circuit applications. They are
pricey but are a perfect addition to our products. Getting
ever closer to the theoretical ideal of pure, frequency-constant capacitance, these
capacitors reduce capacitor-induced distortion to vanishingly low levels.
iFi/AMR ‘OV’ series stands for ‘Operationsverstärker’
(German for Operational Amplifier). The ‘OV’ range ICs use
HCOFC (High Content Oxygen Free Connectors) copper
lead-frames and 4N gold bond-wire which are streets ahead
of mainstream commercial chips that use inexpensive aluminum bond-wire and
low-grade/low-cost copper in the lead-frames. Containing four independent FET op-
amps in a ‘folded cascode’ internal design as also found in the ‘HDAM’ circuitry of
certain high end speaker amplifiers,
(
HDAMs consists of discrete surface mount components with short mirror image L/R signal paths. Those
devices are doing exactly the same thing as the op-amps, but outperform the regular IC op-amps dramatically
in terms of the Slew Rate and reduced noise level, resulting in a much more dynamic, accurate and detailed
sound.)
The OV2637A J-FET op-amp used in the ZEN CAN boasts an extremely low noise, low
distortion (0.0001%) and wide bandwidth.
TI low-noise ICs offer great unity gain bandwidth, very low noise
and distortion, high output drive capability, Common-mode and
Power Supply Rejection Ratios of over 100 dB, wide maximum-
output-swing bandwidths and high slew rates.
