Hi all. I'm deciding between the Topping BC3 and the iFi Zen Blue, and will be using mainly the optical out, so I'm not too concerned on the DAC or amp portion. Looking at the Bluetooth chipset, iFi is using the newer QCC5100 chipset for the Bluetooth decoding, while the Topping BC3 is using the previous gen CSR8675. The only significant difference i can see is that the newer QCC5100 uses less power, which doesn't really matter since the iFi is not a portable unit.
Other than that it seems the QCC5100 has higher processing power, but does this translate to better audio quality?
Appreciate any advice. Thanks!
