VENDO: Perpetual Technologies P-3A Upsampling DAC
Do lançamento:
"Perpetual Technologies' goal was to design a new generation D-to-A Converter that would set new performance standards for DACs under $3,000 (...) This amazing product sets new standards in both dynamic range and signal-to-noise performance. At better than -140dB signal-to-noise ratio the P-3A is almost 20dB quieter than any other DAC that we have measured, or listened to, at under $4,000. It presents a completely black background to the music allowing your speakers to produce dynamics that you've never heard from your system (...) The P-3A is truly a benchmark product for this new era of higher bit densities and sampling frequencies."
Specs
State-of-the-art Crystal Semiconductors CS4397 reference quality 24 bit 44.1/48/96/192kHz stereo digital to analog conversion system platform.
140 dB signal to noise ratio
120 dB dynamic range
Crystal Semiconductor CS8420 digital input receiver / sample rate converter – accepts 16 to 24 bits, and sampling rates from 32 to 96 kHz.
Auto-upsampling inputs - converts *ALL* standard CD’s to 96 kHz.
Future upgrade support for 192 kHz.
Built-in jitter reduction circuitry – based on an ultra high precision, low jitter, quartz oscillator used to generate a stable reference frequency clock, upon which all conversion processes take place.
Class A high-current audio output stage with 5 pole split passive/active anti-aliasing filter surrounding high-performance
Burr-Brown OPA134 driving the outputs.
Digital phase inversion selector (user selectable)
110V Power supply unit included
etc
Rear Panel Inputs (4 digital inputs):
- S/PDIF coaxial
- Toslink
- AES / EBU,
- I2S
Alguns reviews (c/ fotos):
"All in all, the P-3A is a very musical and involving piece of gear which I can heartily recommend on its own, especially at the very competitive, internet-direct price of US $799" ( http://www.audio-ideas.com/reviews/digital-sources/pertpetual-p1-p3.html )

O P-3A encontra-se em perfeito estado e funcionamento !
Preço: US$ 650
Um novo no site da Perpetual nos EUA custa US$ 799.
PS> Não tenho cabo I2S. Tem manual e caixa original. Estou em Campinas-SP.
