Upsampler SNR 121db vs 145db

Upsampling is a tradeoff between accuracy and processing power. Greater accuracy (as in 145db SNR) demands more processing power. By accuracy, I mean correctness of signal amplitude calculation. In the graphs, plotting 145 and 121 will show differences in signal amplitudes (which probably won't be visible graphically and instead, you'd have to look at individual sample values).

So for best 24/96 output, use 145db upsampler. Likewise, at 24/192 you can choose the accuracy you prefer. Using 145db demands better hw.
