MisterRogers:
Hey Mates,

We're finally ready to release the dual mono AK4485S DAC many of you heard at the Denver week a few weeks ago. This DAC is the result of a collaboration between JLSounds and myself, so I intend to make it available here in the states. I intend to price out a matching case for those who simply want to install components and begin enjoying one of the best DS DAC's I've ever heard.

I'll post some new photos soon, but I thought I'd get this up.

The final design took a little longer than anticipated - resulting in several stages:
 
* First stage, the analogue circuit was designed for ‘through hole’ components.
* Second stage, the analogue circuit was reworked for SMD components.
      The idea was to compare both designs sonically. Many different listeners at different gatherings verified the SMD design to be as good, or better than the first stage through-hole design. Corrections or tweaks were identified during testing to insure the best possible sonic performance.
* Third stage, apply these changes to our SMD board.
We’ve also designed a control LCD indicator board, along with the firmware needed to provide complete control of all DAC chip features.

Specifications

USB (XMOS based) input: up to 384kHz 32 bit, up to DSD128 AES/EBU up to 192kHz, 24 bit, S/PDIF up to 192kHz, 24 bit, Optical up to 192kHz, 24 bit

* Outputs: RCA (Single Ended) & XLR (Balanced)
* All available features of the DAC are accessible via indicator board / firmware
* 5 different sonic filters
* DSD mode - volume bypass and normal path
* 5 different sound quality settings
* Volume control
* Phase inverting
* De-emphasisRealization

* Two AK4495S DAC chips are used in a Dual Mono configuration
* Discrete power supplies - one per channel
* Pre-regulator / LDO for digital circuit
* ADM7150 LDO is used for oscillators
* NDK NZ2520SD oscillators, optionally Crystek CCHD 957’s can be used
* All inputs are Galvanically Isolated
* In the analogue circuit we’ve only used PPS Film capacitors, no ceramic ones. All signal path resistors are Susumu.
* To power this board one will need three transformers: 2x22V and 1x12V.

Hands:
Looking forward to being able to really listen to this extensively and compare with other DACs!

Hroðulf:
Didn'tchya hear? Delta Sigma is dead!

Patiently waiting for photos...

Also - are digital inputs reclocked in any way?

audiofrk:
Interesting, what will the dimesions be?

I wanna  post this in the cavalli dac options thread on head-fi.

MisterRogers:
Just need to dig up my mechanical drawings - I'll post dimensions in a few. POSTED ABOVE.
