Well the dac was bought from London in my last visit there infact my whole audio system is sourced from there. Not sure if its still available in India. I also tried Rega, dragonfly. Some more expensive ones which I tested were NAD M51 (which is also a preamp) and Metrum. To my ears NAD sounded the best which it should given the 1500 GBP price tag (if you ever get a chance do try it ) For some reason Metrum sounded bit thin unlike the glowing reviews which I have seen.
As for the rest Halide sounded the best, I wanted to like the Rega but just couldn't adjust to the sound which was lifeless over USB but using a SFDIF converter the sound really opened up. For dragonfly it sounded much more compressed compared to Halide. Incase you have PC with a digital out then you should give Rega a try but strictly for Audio using PC I thought Halide DAC HD was the best bet. It really gives analog like sound, bass was quite tight unlike that of dragonfly and with a very nice midrange.
But end of the day as they all say only trust your ears that's the best judge. Hope that helps.
