To open ended a question for viable suggestions.
As others mentioned budget, intended use, source, local/abroad etc are certain parameters that have to be defined first.
If your budget is around a lakh, then the Chord 2Qute is a brilliant piece of equipment if just a DAC is what you need without the extra features of a pre-amp and headphone amp...else for all extra features, the Chord Hugo is equally good but more expensive...
There is an Audio-gd on sale here in the forum. Look in the 'For sale' section, to boot it is in Kolkata. In your budget too, hear it, and then carry it home!
