Metrum Pavane NOS DAC

The Schiit Yggdrasil is also R2R using 4 $75 exotic 20 bit super precision Analog Devices DACs to give "pure 21 bits of info". My friend has one he lightly modded and he says its outrageous. You can see the mods on my website: http://www.tweakaudio.com/EVS-2/Schiit_mod.html
He is in Pocoima, CA and would love to A/B with the Pavane or other fine DAC.

I am not totally sure but I think the ad5791 has no internal IV converter. If you make a discrete R2R DAC as MSB and TotalDAC do they both have voltage out without an IV converter. I think the same for this part.

George,
As I described earlier it is possible to make an R2R DAC that has voltage out and not current out. This is what TotalDAC has and so does MSB. They do not need IV conversion. Maybe the 5791 does the same. The amount of voltage out on the 5791 is determined by the power supply voltages you use on the DAC. The Yggdrasil actually puts out 4.6VRMS out of each DAC chip (4.6V per phase). This was just measured on an Yggy today. There is no measureable DC offset on the output of the DACs. The voltage coming out of the output stage buffers is 2VRMS per phase so the buffers actually lower the voltage coming out of the DAC. I will call Analog Devices on Monday and ask them if there is a built in IV converter.....I don't think so. Anyway, the stock Yggy sounds great and the modded one sound way better and now I will be putting my zero feedback fet buffer on the output instead of the Schiit stage and see what we get....fun times ahead.

According to Analog Devices the 5791 has no IV converter....voltage comes straight off the resistor string.

Now back to your scheduled programming.
