Sonore Signature DAC/PREAMP

The Signature Series Sonore DAC is the result of a two year R&D project collaborating with industry innovators, Raleigh Audio and K&K Audio. Based on their tried and true RAKK dac, our new digital-to-analog converter is specifically designed to get the best performance possible from our server, allowing 24-bit 192kHz high-resolution file downloads to be exhibited in their true splendor.
The performance of the Signature Series Sonore DAC has a huge soundstage, as in wide, tall and deep that will fill your audio room with gorgeous music. The sound is very relaxed, not at all displaying the digititus sound so common with many modern DACs. To me it's like everything is in its place and nothing is trying to get my attention or nothing is a distraction from the music.
The Signature Series Sonore DAC is designed and manufactured by a true craftsman in the USA. The modules that make up the heart of the Sonore DAC are assembled in the USA with the highest quality parts selected from around the world.

Support for legacy SPDIF and AES/EBU interfaces.
SPDIF and AES/EBU digital inputs are transformer-coupled to provide isolation from the source.
I2S digital inputs are galvanically isolated.
PCM digital audio data is up sampled to 192KHz for the minimum digital-to-analog aliasing artifact generation.
Each digital section has its own separate galvanically isolated voltage-doubler bulk power supply.

The Active Output Stage is a differential class-A triode parafeed output stage.
The amplifying device is the Russian 6H30P dual triode.
The output transformers are the superb amorphous core Lundahl LL1674 units imported from Sweden.
Analog outputs are galvanically isolated.
Dual-mono high-voltage Minimal Reactance Power Supplies are integrated onto the Active Output Stage board.
The switched attenuator volume control allows direct connection to your power amplifier without needing a preamplifier. It uses a Seiden 32NEG switch imported from Japan and SMT resistors selected to provide the best possible sound.
