Dongle delight from HiBy Music looks like Darwin R2R. The FC6 DAC/amp packs the latest version of HiBy's growing R2R capabilities.
Controlled by code from a FPGA, there is nowhere you cannot enjoy the discrete resistor DAC Head-Fi has come to love from HiBy. Being an "endearing standout R2R dongle DAC rather than a ‘me-too’ copy" drew praise from Headfonics.
With the work and skill it takes to design one's own R2R resistor DAC from scratch, and place it into a portable dongle, we must say: FC6, like RS2 and RS6 before, is proof of how far up the ladder HiBy have climbed.
We've heard multiple times it's not a matter of parts but the implementation that counts. So we pay attention when FC6 coverts PCM and DSD via separate circuit paths, doing so for the former ala typical R2R – NOS (non-oversampling). MOONSTAR Reviews enjoyed finding NOS in a dongle this size! [See Product Desc. For More]
