Yes, the boards are mono as Stefan says.

Here comes a block diagram (hope it makes sense....):

Do you really need the I/V's? can you run voltage out at all on the B3?
SMPS are also an option that would simplify the huge amount of power circuitry maybe ?

Love the work, would love to get my hands on a few of the boards.

I used voltage out in the previous build. I think it worked good, but since I had the boards and parts for I/V's I'd like to use them. And I *think* is sounds better with them ;)

Now, I plan to get a second miniSHARC in the box as well... :blink:

Thanks Crumboo !

All is working now, i've just made a shortest flat ribbon and use only one ground pin on the sharc (but with all the grounds coming from flat ribbon attached on).

Good work for the adapters !

Hi Foyus,
Is it possible to see (or to get) the photos of your proper wiring between the BIII and MiniSHARC?
I think I don't correctly understand what means "use only one ground pin on the sharc (but with all the grounds coming from flat ribbon attached on)". Is it means that you solder only one ground wire of the ribbon on the SHARC side but - all ground connections (one for each signal line) on the BIII side?
Thank you in advance.

I have SL's LX Mini + Subs speakers. I'm currently using nanoDIGI plus 3 DACs (cs4398), great results, but I want to build something new. Getting rid of S/PDIF and going to I2S would be fun.

I'm thinking Amanero USB to I2S --> MiniSHARC --> Buffalo III

In your miniSHARC with Buffalo III, is miniSHARC running as Master for: Input, Output, Neither or Both?

p.s. Awesome build you have!!

Hi,

I am planning to implement a similar setup as to the ones shared in this thread. I have searched and read through several threads here and twisted pair and just want to make sure what I am planning makes good sense. I have a 3 way open baffle speaker system.

My current idea is to use an OPPO 103 as my source, connect that to a DIGI-FP, connect that to a MiniSharc (as my DSP engine), connect that to a Buffalo III DAC, connect that to 3 IVY-III boards(or build my own), connect that to ATI AT52xnc power amps to drive my speakers. I will get power supplies from MiniDSP and Twisted Pair for each of the units that I plan to use. There are several parts to this that will be a new endeavor for me, the MiniSharc and the Buffalo III DAC mainly.

My question is: Do I have any glaring problems with what I am proposing? Am I missing any boards from MiniDSP or Twisted Pair that I need to implement this?

Thank you in advance for any input!
