I need more voltage out of the IVY-III balanced outputs. How high can it go with higher values for R13-R16? I would like about 12 volts peak differential, with is about 8.5V RMS differential.
That's asking a bit too much (not enough headroom) You could get pretty close though as long as you use 15V rails and the impedance of the next stage is high.
I would try 470R at R13-R16 and see if that is enough gain for you. Those resistors should be closely matched to each other.
Cheers!

How many U.fl cables do I need to connect a waveio to my b3se? 3 or 4 ? I don't know if I have to connect the master clock cable ... Thanks
Ok answering myself, after reading this topic http://www.diyaudio.com/forums/twisted-pear/215775-my-thoughts-miniature-coaxial-rf-connectors.html I don't know if it's a good idea to buy U'fl cables. But what kind of cables is the best for soldering I2S input from a waveIO card? Silver/Copper/PTFE ?

I went for u.fl at the "WaveIO" and soldering at the buffalo end.
Tried soldering the u.fl's but it was a little bit tricky 😱 so I skipped that.

I was thinking about soldering both pin headers and u.fl connectors onto the B3-SE. Any reason I shouldn't?
As another Wave IO owner, it might help if you pre solder the ground ufl connections, and then tap the solder with the connector in place. Then use flux for the + pin on back. Maybe pre tin the + pin as well to get the solder to flow quick and easy.
I made a short video on how to hand solder the u.fl connectors here: Hand-soldering u.fl connectors - YouTube
Hopefully it makes it a little easier. (Sorry for the shaking camera... I kept hitting it with my hand.)
That's how I did it, but I was shaking a whole lot more i'm afraid 😛
I've done smd before but one way or the other I found these parts difficult to solder.

I think I won't use these U.fl, I want solder these cables, but what kind of them ?

It does not matter much, just use what you like. If I am soldering small gauge wire, I like to use PTFE/Teflon jacketed wire, as it will not melt and pull back when heated. I would not go crazy ($$) picking the wire.
EDIT: ApexJr has a good selection of PTFE at a good price: http://apexjr.com/wire.html

Also, does the B III-SE work in mono mode, or is it only Stereo? thinking about maybe going passive with two dac boards and ~32mA per channel, that would suite a 1:25 transformer perfect with 1R to GND!
Question...
Buff 3se on waveio
spdif work fine
i2s lock is off and mute is on
BLCK - DCK
LRCK - D1
DATA - D2
GND - GND
with isolated i2s the same result
buff 3se all switch on
idea ? 🙂 thanks a lot

Hi Russ
It plays perfect on i2s now 🙂
many thanks for the quick response
I should study the manual better🙄😉

Does the BIII SE need an earth reference? Or should one just let it float? I am using a power supply without a mains earth. Should I connect the PS regulator GND and BIII GND to chassis? (chassis connected to the RCA outputs 0v)
I am using a transformer for analogue output to a SE amp so the secondary could be left isolated from the DAC chassis, but the BIII would then be left floating.
thanks,
