I am not sure whether Muljao comment was due to specific knowledge of the A-S3200 (and I have not hear this specific yamaha), because potential benefits from XLR will depend on how well the internal circuit implementation is executed, but on equipment where it is done well, there can be a benefit over equally priced RCAs. The level of benefit could also depend on how much external interference/noise there is in the area of your cabling as properly implemented (and I doubt Yamaha would not) XLR has a normal and inverted signal which when 'summed' allow the identification and removal of noise. Which is why they are used for studio applications, etc. On my current systems which have dCS, Vitus, Trinnov and Dan D'Agostino components XLRs are superior to RCA, noting that Dan D'Agostino does not put RCA inputs on his power amps. I have undertaking extensive comparison trials here with multiple cable makes including Chord, Nordost, van den hul, Tellerium-Q and ended up with the higher end Chord XLRs on that system. But I can also say I had XLR improvements on the previous Yamaha AV system I had using the CX-A5000 to both Anthem and Yamaha power amps. I found recently in helping a friend set up their system that the Chord Shawline XLRs were a worthwhile improvement over the baselevel ones into a mid-priced power amp. For these reasons I would agree with AL ears, see if you can borrow a set of XLRs and try them, how easy it will be to do in Lockdown I am not sure, but Richer sounds used to let you borrow comparison cables for a deposit. You may need to check with the supplier but Chord also did have a money back satisfaction guarantee. I'd also say that if you find a trial shows an improvement you could get a bargain buying a second-hand pair of old model "higher-spec" cables I picked up some Nordost Blue Heaven XLRs for under £100. Hope that helps.
