The difference in sound quality with power supply and decoupling caps is very interesting. The IC PurePi 5V UC supply didn't have much height, for some reason, but it's super quiet and the deep bass is amazing. The Allo 5V 3A supply had a bigger soundstage, but it's noisy and the bass is not nearly as good. The LifePO4 seems a good compromise. I think the value of the decoupling caps changes things, too. These observations are on my system and may not translate to other systems. It's a slow process. The decoupling caps take 60+ hours to break in.
