Difference in Quality between UR22C and UR22

[Y-D]

They probably included a number of other improvements, but 32-bit recording has nothing to do with improving results over 24-bit (used properly).
You can read my comment on 32-bit half-way in my too-long post here :

Outputs - balanced wiring or not?

I have a 44C and will grab my ohmmeter tomorrow and will make that test for you. However… Having a balanced connection for a high-impedance input (like a mic pre-amp) makes a HUGE difference (for noise immunity), while for a lower-impedance input (like on a line out) it makes little or no difference. So unless your cables going to your monitors are long and going around very noisy sources (ex. a frig compressor!), you will never ever hear a difference. I’ll make your test anyway, but it’s irre…

The UR-C series are great units!! But 32-bit recording is pure marketing fluff.

N.B. The 32-bit “integer” format of UR-C units is not to be confused with 32-bit “float” format, esp. when combined with dual ADC converters! Two completely different beasts.
