John Grandberg has posted a review of the Cayin iDAC-6 DAC ($999) and iHA-6 headphone amplifier ($999) at InnerFidelity. His conclusions:
“At $999 each, these two straddle some sort of line…I’m sure some would call them “affordable” while others would balk at that price as being way out of reach. Personally I think it’s actually a somewhat interesting space—we’ve got plenty of affordable gear in the sub-$500 range, and lots of all-out-statement type pieces with huge price tags, but not as much in between those two extremes.”
