RE: Improved Regen sound

Thanks again, Pictureguy, you seem to have a good knowledge of battery chemistry. What we want to avoid is a regulator on the battery output. Can you nominate any others that have 3.3V output & a similar discharge curve to LiFePO4 batteries?

Regulation from my experiments so far, have proven to be noticeably detrimental to the sound when compared to using power from the batteries directly.

I've mostly used these batteries on digital ICs which require 3.3V power. I'm not sure if it's the low noise (especially at LF) or fast transient response that accounts for their advantages in this role? The only regulators which seem to come close to these batteries are the Paul Hynes ones so it's possible to build. He has different regulators for different roles, digital or analogue power, low current or high current & he emphasises transient response for digital but I would also add low noise at low frequencies as also being important for clocks, etc. These batteries seem to check both of these boxes

I've also tried them on smallish, chip-based power amplifiers & the improvements were also noticeable
