Dude, yesterday you couldn’t afford a new DAC but today you spent $4K on one but only if they would ship it today. Then you ask for advice on speaker cables and 5 minutes later say never mind I bought some Wireworld’s.
let me save everyone here sometime time and energy; You have an awesome system and are making perfect choices.
The only advice I can give you is no matter how good your system is, it will suck when anyone else hears it on a Facebook video.
btw what kind of car do you drive? Again?
