@journal - out of the above mentioned DAC's I have heard/owned hifi rose, mhdt, Chord, denafrips. To me out of these 4 brands, a chord qutest at approx 1 lac is the best. If I was in your place I would get a wiim pro (I own one - 20k at hifi mart) and run it into a qutest at 1 lac. This combo, again imo will beat units/combos upto 2-3 lacs. However due to wiim pro lacking usb out for audio you will not be able to experience dsd. For that you can consider upgrading to lumin u2 mini down the road. With this combo., (2.5 lac) you will easily approach 4-5 lacs sources again imo.
All of the above are based on my listening, and the formed opinions consequently (and as Jai mentioned above an R2R dac sounds very different to a chip based dac which sounds different to a fgpa dac). The qutest is a fgpa dac.
A very unpopular (due to geopolitical issues) but regardless solid sounding DAC should you consider the China hifi option is the SMSL (D400 pro at $600). To me this one beats the Chord qutest, but limited availability in India and has to be imported. It is based on an AKM chip.
