ackoDAC based on ES9018

[acko]

For those whose want something ready built consider the combo series. The latest one shown below has this Synchronous Master Clock. integrated. PM me for DAC user's manual and other details.

[acko]

Mid-range product using 9016 DAC is on the way. Will have DAC, Controller and IV stages integrated with several options. ETA ~4-6wks

Balanced outputs are also present, just not shown yet.

There are on-board LDO/low noise regulators for each of the power input of the DAC chip. Master supply is 5V (4.5V-12V) for DAC module and biploar +/5V to +/15V for IV stage.

nice, I was going to ask about that as they arent present above.

Hi acko,

Three questions:

1. The u.fl and 2.54/5mm pin header stuff at the top centre of the combo you've just shown, are they just there to change termination style available depending on input devices i2s style?

2. With the combo boards is deleting options from the combination a possibility? Ie to purchase the one pictured above without synch master clock, spdif and usb?

3. What is the purpose of the onboard osc in a system with the synch master clock integrated?

A few of us Queenslanders had the opportunity to listen to qusp's ackodac on the weekend at a small get together, I had heard it a few other times before that though, very enjoyable. I'm saving for my own

Ah! So he did manage to take it.
Any pics?

[hochopeper]

I don't have any pics but I believe vitals of the system were nattonrice stick pre-regs, acko AKR, acko AKD12P, SPDIF input via I2S FIFO, 'The Wire' BAL-BAL headphone amp and IV + HD600 that we were listening to. The same system that had qusp posting eargasm and gushing audiophool speak in the FIFO thread not too long ago! For good reason too IMO.

There was some technical difficulties with the usb device power cycling (and having never hooked that device up to either the 2 computers I bought along for the day we weren't savvy to the nuances I guess) but only XLR outputs from that system and nothing that took an XLR input on the day.

Sounds cool!
The usb thing sounds like a pita.
