Yes thanks for the information. Interestingly enough my soundcard interface has a volume range to -132dB to +12dB (144dB) in the software side of things however the actual specification of the DAC won't go that low. The analogue inputs and output are more likely to be 20-bit (120dB) at very most. Also I've seen that DSD developers aren't really pushing the envelope for any claims beyond that. It makes me wonder if I should do dither at 20-bit for futher recordings although some of my plug-ins dithering on the fly internally reducing the need to do it anyway. This is why I get bemused when I see people arguing about the quality of the copper and AWG used for speaker cabling, I'll buy good reputable OFC although not $100's for it.
