The FiiO K9 Pro--Now With Dual ESS DAC Chips

The FiiO K9 Pro Desktop DAC/Amp has become a huge hit thanks to overwhelmingly positive reviews from YouTubers like DMS and Joshua Valour. It featured an AK4499 DAC chip that was in short supply to begin with, due to the fire at the AKM factory in 2020, and is now completely sold out.

Now, FiiO has pivoted to using dual flagship SABRE ES9038 PRO DAC chips by American manufacturer ESS paired with dual THX AAA 788+ amplifiers for a fully balanced hi-fi experience. (The original version featured a single DAC chip and amp chip. The rest remains the same.)
