The
Genesis Preamplifier represents the first product in the Genesis
Project series and was actually given the name Genesis as
per the request of the customer who first sanctioned the development
thereof. This customer had fallen head over heels for the
Black Widow Preamp sound, but required a balanced preamp in
his system. He felt that the name Genesis was apt as this
was to be the first product in the balanced series from Valve
Audio.
The
development model was based around an eight tube layout. Per
channel two 6922 differential stages buffered by two 6H30
followers per signal phase formed the core of the original
design. Power supply duties were taken care of by ten toroidal
transformers, ten rectifier stacks and eight high and low
voltage regulators. Premium quality components were selected
for their sonic attributes, rather than their price tags.
Remote control functionality was a given in this no-compromise
design,with the actual volume control being achieved by phase
cancellation, rather than the traditional voltage divider
concept.
This
concept design attained production status after about a year
of fine tuning and became the very successful Original Genesis
Preamplifier. |
| The
second generation Genesis Preamplifier strongly draws from
the design roots of the original model, with a complete revamp
of the power supply methodology. Three dedicated toroidal
transformers replace the ten of the original model, with five
rectifier stacks and a ten regulator layout. All signal capacitors
are replaced by the magnificent Cardas Golden Ratio TM Signal
Capacitors. Where customer preference dictates, the equally
supremely musical Hovland Musicaps are used with absolutely
amazing results.
