The Peachtree Audio ‘Nova’ is an integrated amplifier
with a built-in DAC. Heralded as the perfect computer audio integrated amp, the
Nova is equipped with a hybrid amplifier using 6922 tubes for the pre-amplifier
and a solid state MOSFET power amplifier. A unique feature with the Nova is the
choice of DAC, an ESS 9006 Sabre 32-bit DAC which
to date has only be used in a handful of commercial products.
Since
many users have bought this fine product to use the high performance DAC we set
the task of pushing the performance further with our upgrade modifications. The DAC audio board get the fundamentals right
implementing 11 regulated power supplies, extensive bulk decoupling to keep
noise at bay. We have two levels of upgrades available; level-1 replaces 22
general purpose electrolytic capacitors on the audio board with Sanyo OSCON SP
type. The NE5532 op-amps for the audio
stages are replaced with LME49720. To complete we replace the 4x 20mm fuses
with 24K Gold Audio Grade type from Isoclean.
