ProtoDAC TDA1387 X8 project

[OnkelPH]

Regarding power supplies, I am planning to build a 5V 2S 18650 LifePO4 supply using this Ali BMS and my favorite linear regulator (LT1963, this module needs a general purpose 10uF cap added to the output, DS recs 10uF 50mOhm to 3 Ohm ESR). I think it can be built for <$20.

Hoping to answer the question: What is the difference in sound quality between a low ESR ultra cap PS and low ESR LifePO4 PS?

The added linear regulator might add its own sound character, but no other way to get 5V from 6.4V.

Really looking forward to hearing the results.
