New upper trim level Corvette or seven year old used amps?

Recently I have experienced quite a few people I know either passing on or being diagnosed with some type of cancer. And as I have never strived to be the richest guy in the graveyard, I was thinking of buying one of the new Corvettes. I also started to look at my older tube amps, good, but I had had them for about nine years, and the whole tube thing....then I started to think about some SS amps( I know, I’m going to hell). TAD M600, Dagostino M400, and then ventured into Dartzeel territory. Long story shorter: I came upon a pair of used Dartzeel 458’s, totally crazy price, totally crazy good. I have had them about a month and have enjoyed over 100 hours of listening nirvana. Had I bought the vette and drove it 100 hours, I’d have lost my drivers license, and spent thousands on tires, fuel, fines, etc.  
myth buster: it’s all worth it! Expensive power and speaker cables, interconnects, speakers, and Dartzeel 458’s.
Anyone that tells you otherwise is using cost not quality as a determining factor.
Enjoy the music and Life
