I’ve said it elsewhere and say it again here: the weak link in 99% of audiophile systems (aside from room acoustics) is the speakers. Even if lamp cord is being employed as the speaker cable in an otherwise $50K system, it’s not likely to be the weak link.
Speakers, speakers, speakers…everything else is a distant contributor. I’d rather pair $30K speakers (or $10K DIY speakers) with $5K in electronics than $20K speakers with $15K in electronics.
