JerryBJI know exactly what you mean. The cables I've bought in the last year are hopefully my last, with retirement a wee way away, but certainly a factor. The Audience Au24SX are certainly my end interconnects. My ATC SCM19v2 are my 'end game' speakers.
Top quality stuff. Don't let the media / marketing shills or the mega rich (who want to feel special) try and convince you anything is lacking. If you are happy with them enjoy!
This is what price to performance in audio boils down to. Marketers that want to sell a dream at outrageous prices. And the people with more money than brains that want to make you feel humble and try and justify their purchase.
