@gillj re:...
Are there specific features that are important to you when selecting a DAC ?
Of course...
- does the DAC use R2R/multibit or Delta-Sigma
- the DAC Chip manufacturer e.g. Burr Brown, Wolfson, etc..
- does the DAC have a physical volume control
- what are the sample rates supported e.g. 16/44, 24/96, 32/192 etc...
- does the DAC support Up-sampling, or non-up sampling, or both
- the number of inputs and outputs
- the type of inputs/outputs - i.e. SPDIF, Optical, USB etc.
- the type of input/output connectors..e.g. RCA, XLR, BNC etc..
- the type of power supply/connector i.e. Mains/IEC connector, Mains/C7 Figure 8 connector, In wall (i.e. Wall-wart) DC supply
BTW - That’s not an exhaustive list, just some that I have considered
