The Kuartlotron - keantoken's simple error-correction superbuffer

my attempt at building the K Buffer. i mostly followed the thread on hifivision forum and also got the pcbs from a forum member there [he is active over here as well - Sachu]
this is my first ever DIY attempt in audio. K buffer coupled with Source Selector module [with remote]

i know wiring is a mess, but it works! the thin black hopping wire on the right over the signal cables is a ground cable - only one end is grounded to power ground.

initial impressions are very positive. mids and highs are sounding crisp now! my sub integrates better with the music!
being my first DIY, i wasn't expecting much of an improvement. i would have been happy even if i had managed to retain the same sound quality :p
my chain is Foobar on laptop-> Muse DAC -> K Buffer-> Swans 1080 IV monitors + Yamaha YST SW-215 sub

finally thanks to @keantoken for this beautiful buffer design!
