The Purity Reference is a Class A, transformer coupled balanced linestage
and is the result of years of intensive research
directed at attaining the most accurate reproduction of recorded
music. Unique topology and application of the most
advanced technological resources and processes bring the Purity Reference to a threshold of excellence in sound reproduction. To add to
the main features, the
Purity Reference utilizes transformer coupling at both the input
and output. Transformer coupling output results in a low output impedance
making the Purity Reference a versatile unit that is capable of
driving both solid state and vacuum tube amplifiers. Extraordinary transparency of perceived
sound which in turn assures the recreation of a three
dimensional soundstage.
The full function remote
handles mute, balance, source selection and phase inversion. The
volume is handled by a modified shunt type hybrid resistor
design with precise 1dB attenuation steps.
The best sounding volume control next to
autoformers is one that has the least resistance in the path
and can maintain consistency throughout all frequencies, for
this we chose to use relays.
With
3 sets of balanced inputs, 3 sets of unbalanced inputs and 2
sets each balanced and unbalanced outputs, connection
possibilities are vast. When an unbalanced input is selected,
the signal still passes through the input transformer
maintaining a low output impedance as well as the resolution and
transparency transformer coupling is known for. Absolute phase
and balance control are selected both through the supplied
aluminum remote handset and the front panel controls.
As with all
Purity Series products, the remote circuit has been granted a dedicated power supply including a separate, standalone
power transformer as not to interfere at all with the analog
circuit.
