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!

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 :eek: so I skipped that.

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

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,
