Great, can't wait. Al, if I could be of any help, please let me know. I'm retired and plenty of time on my hands, though I'm a software engineer, so when it comes to hardware I freeze...;-)

Hi Alex,
I let you know if I need additional help. Thank you so much for offering.

Quick Update
Hi Everybody,
I've started populating the new DAC and I/V amplifier board to make sure everything works. The new changes are minor but I want to be 100% sure that everything works before going into full production. The PCM/DSD and S/PDIF input boards, OLED control board, and power supplies will be here next week.
The plan over the next two to three weeks is to complete another DAC build including all the new boards. I thought about skipping this step since I've done so much testing already but experience tells me the added time and expense will be well worth it and give me peace of mind.
I don't anticipate this will push back my previous schedule too much. I still plan on being ready to take orders in December, and go into full production sometime in January.
Best regards,
Al

Hi very interesting project, if i can order fron you in early January, I want a 4 channel kit, one dac and two amp board. I´m right? Thanks
Hi cloudalmasai,
I'll try my best for early January but most likely it will be mid to late January.
You're right for four channels you'll need one DAC and two Amp boards. So you'll have two DACs in parallel per channel.
Thanks for the interest.

Ok, thanks. In that timeframe is perfect for me, I will follow this threat for your updates.
PD: sorry for my crapy english.

Hi Alex!
My Fav DAC chip and Fav open-development baord. Nothing could be better.
I just got a Cambridge Dacmagic for my Stero setup ( NAD 320BEE/KEF Q300), which could not win over my makeshift Audioengine D1 - the limitation of 16bit in USB mode on CA Dacmagic sucks.
So here is what I need:
1. The 2.1 Stereo output (Yes, a nicely done sub out is great)
2. No Amp stage. Only balanced RCA.
3. Take advantage of of input sectors:
a. 3x S/PDIF
b. 3x Coaxial
c. 2x Asynch USB.
Do let me know the price of the kit/PCB of for my required setup.
Eagerly waiting for your announcement of the board.

Hi Kuribo,
Thanks for the continued interest. I've been working on lowering cost as much as I can. Pricing will be similar to lower than other ES9018 kits currently available. I'll announce the numbers early next month after I'm done building and testing all the new boards. Stay tuned for pics of the new build. December will be a very busy month. Thanks again.

Hi AAK, I'm very interested in the I/V boards for an active 6 channels project. I already own a Buffalo III DAC and I wondered if I could easily connect the I/V boards to the existing DAC headers (which can be seen here : The Buffalo III Digital-to-Analog Converter).
Thanks!
Thanks!
Hi Zaireeka,
I doubt the headers will align correctly, but you can easily wire the connections. Should work great.

Al

Hi AAK,
I posted earlier with less understanding. I am having a Stereo Setup and using CA Dacmagic to power my Amp, and using 2xS/PDIF inputs. I am not very impressed with the CA DAC and would like to upgrade that DAC and somehow get a Sub. I looked at commercially available Pre Processors like Emotiva UMC-200 and Outlaw 975. I would need a unique configuration from you, somewhere between 8-Channel and 2 channel where you apply HPF on L-R channels and a LPF for Sub Channels, and 3 I/V for the L,R and Sub. I would also need the 1xUSB , 2xSPDIF and rest Coax.
Could you please see if your current designed be scaled to this kind of configuration with MCU, 3 I/V and other input boards.
Regards,
Ujjwal

Hi Ujjwal,
My design can be configured to work with your application, no problem. The DAC/Amp output section supports up to 8 channels. The input section can handle up to 8 S/PDIF channels, balanced AES/EBU, Coaxial, Optical are all supported and can be configured in any combination you want. The input section also supports two stereo or multichannel I2S/DSD inputs.

Thanks for the reply AAK. So Please Add me for a 2.1 Stereo Kit list . I would need the main DAC, MCU/Rotary, 3x I/V, 1xUSB , 2xSPDIF boards and the PSU.
Would be so eagerly waiting for the new year when you would be announcing the Kits!
Thanks
Ujjwal John.

Hi AAK,
I would like to know if you had some free time to determine an approximate price for your wonderful kit?

Hi Alexandre,
Not yet, I've been way to busy with my regular job, and testing all the new boards on my free time. I'll need the holiday break to get it done. I'll do my best to announce pricing for the entire kit by the end of the month.
There is some good news to report though. The new DAC PCB works beautifully and sounds great. I also modified the firmware so the OLED displays volume with 9 characters per digit instead of one. The numbers can now be seen clear across the room.

Hi Al !
Please Add me for a dual mono kit list . I would need the main DAC, MCU/Rotary, I/Vfor dual mono,XLR out, 2xUSB , 1xSPDIF boards and the PSU,possibly with some changes.
OLED displays is fantastic upgrade from regular LCD disp. Bravo!
I would like to know if I can connect on the output I/V headphones with an impedance 32 ohms? Thanks!

Hi jazzbear,
I've added you to the list. Thanks! The balanced outputs from the LME49600 can handle 32 ohm headphones with a power dissipation of about 0.5W.

Hi Everybody,
I've attached a couple pics showing the OLED display set up with larger volume characters, and a pic of two of the new DAC boards stacked operating in stereo with 8 DACs in parallel/channel.
