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
-Lossless Digital Volume Control
-Advanced connectivity for Remote Control options of DAC via PCs, Tablets, IR remotes, SBCs or SmartPhones. Web/IoT capable. Remote Media Player Control options-e.g. Roon
(View/Set registers). Multi-master control, display port.
-Advanced features: THD Compensation and AGC for matched performance. Load custom filter profiles.
-OS & hardware independent Comms API. Allows open-source control option.
-Low-level I2C comms or easy to use high level functions
-Mono, Stereo and Multichannel versions. Controls up to two DACs automatically
-Master control option of other connected devices
-Trigger Output for power amps or AV systems
-User's Manual with comprehensive integration guide and support information provided.
-Supplied as shown. Options are extra at cost.

Reviews:
-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!
