Can't count the many times I've observed the oft repeated mantra of illogic that believes no further improvements available, and this applied to every single component in audio systems. And then these individuals open their minds to trying the things more experienced audiophiles suggest, shazam, new converts!
Funny thing is, I don't see individuals, at least within all the audiophile forums maintaining long term static setups. If one already had a setup that couldn't possibly be bettered, why would you change a single thing, and furthermore, why are you even involved in these forums. If I was as truly happy as these individuals profess to be I'd not be involved in any audiophile talk, just blissfully happy and ignorant in my little bubble. Seems some unncertainty here, just jump in, the waters fine!
