The better a recoding is the better it sounds through a class A system

for example a Jobim Verve album


Signal path:


Carlos Jobim CD - Sony CD Walkman line out bridged - Pleiades BD139 class A no feedback with output matching transformer - 4Ω linoleum Pleiades Auratone 5C type cube speaker - reverberant room


Class A operation means electrons flowing all the time
