The Anniversary Custom is revolutionary in the world of audiophile mc step-up transformers being the only transformer in the world to feature dual cores (per channel) for hum-cancelling, giving at least a 20dB reduction in the pickup of external magnetic fields. It also features a very low-loss core material, multi-layer winding and adjustable loading for both the primary side of the transformer and the secondary side. The bandwidth is wide and flat with excellent transient performance. These features make this the ultimate step-up transformer for today’s state-of-the-art low output moving coil cartridges.
Hum-cancelling design
The Anniversary Custom employs two transformer cores per channel rather
than the usual one, enabling the cancellation of any hum picked up from
stray external magnetic fields. This unique feature, found on no other
step-up transformer in the world today, allows the user to enjoy music
with an exception signal-to-noise ratio.
Hand-wound coils
We carefully hand wind each transformer in-house using multi-layer
winding techniques to minimise inter-winding capacitance and maximise
the high frequency extension for beautifully clean transients.
Primary load adjustment
This facility lets the user select different loading resistors on the
primary side of the transformer which act on the cartridge directly to
alter the load impedance it sees. Six settings are available to fine
tune the performance.
Secondary load adjustment
This facility lets the user select different loading resistors on the
secondary side of the transformer which not only alter the load
impedance set by the cartridge but also have a subtle effect on the
performance of the transformer itself and can extend the low frequency
response of the cartridge/transformer combination and damp the high
frequency response. Six settings are available and used in conjunction
with the primary load adjustment there are 36 possible combinations
available to fine tune the performance of the cartridge.
Cartridge compatibility
The Anniversary Custom is optimised for cartridges with output voltages
in the range 0.3mV to 0.5mV and with coil impedances in the range 4 ohms
to 6 ohms. This makes it ideal for use with many cartridges from
Ortofon, Lyra, Koetsu etc. It is also compatible with cartridges with
any coil impedance of 12 ohms or below.
