A couple years ago I built a little SS phono preamp kit from DIYAUDIO that was designed to run on batteries. I was interested because I wanted to see the differences between 9 Volt batteries, SLA, and LiPo would sound like.
The 9 v batteries was horrible. The big SLA was a bit better and the LiPo was the best, probably because the internal resistance of the LiPo was the lowest.
The less than $100 board still was not very musical so I tried using a leftover shunt regulated PS from Twisted Pear that supplied mort than 10 times the required current and the sound was great.
In fact that phono preamp is living in a friends Uber system replacing a $6500 Ron Southerland phono and my friend could not be happier.
But....
My friend just cannot live with a cigar box phono preamp in his Uber-system so at his direction I am building for him an AN L3 phon preamp at almost $2k for him. Will see how this compares to the cigar box.
Auidiophiles are funny.
I would be proud to have a cigar-box preamp that beat a $6500 one, and would make it the visual centerpiece of my system.
