AKD38 Ultra DAC

ESS 9038PRO-based DAC in stereo, mono or multi-channel...

-I2S/DSD inputs direct-- up to 768KHz PCM and up to DSD1024 options

-Modular design, flexible options, integrated solution.

-Optimized direct connections. No jumpers, switches or links in signal paths.

-4 layer, 2oz Cu, Gold Plated composite board optimized for high speed mixed signals. Split power planes with star-point grounding.

-Wiring mostly embedded on board

-Precision metal film resistors and COG capacitors in critical sections

-On-board low phase noise clock. Options for on-board clock upgrade, Dual Fs Clocks and external Master Clock

-Asynchronous, Synchronous clocking schemes

-Individual x8 ultra-low noise linear regulators, 3-Term type, for each power section of DAC - no sharing. Can be removed for upgrades.

-Ultra-high performance IC OpAmp I-V for Output Stage.

-Ultra-low distortion line outputs, THD+N: -120dB typ.

-Direct-coupled Balanced and SE outputs. All fully balanced processing, even for SE outputs.

-Precision nulled output offsets; < 200uV (direct trimmed - no noisy dc servos used)

-Full Control of DAC module via on-board switches, memory or remote control.

-All separate power supply points:

5Vdc master supply for DAC section (wide range 4V-10Vdc regulated, raw dc or even batteries/SuperCaps) - reverse polarity and over-voltage protected up to 16V.

+/-15V for Output Stage power

-Advanced Thermal Management for reliable operation right up to the highest Fs

-High performance DAC Controller with NV flash memory for 'soft' switches and settings. Galvanically isolated from DAC for minimal interference

-View/set registers.

experiment different settings and save configurations without having to update firmware

... This is the best sound I have ever had from a DAC in my living room and beats my previous ES9018 Dual Monos

..Your attention to detail and quality of your product is unsurpassed!!! ... I am finding it hard to impossible to go back to my previous DAC even for short period!

-My 8-channel active crossover system (which has AKD38 running in the voltage-out mode at its core) is fully operational now, and I am very impressed with its performance. Thank you for making this DAC available!
