Tantalum Capacitors in Signal Path

Hi Guys!
I remember that in the late 70s or early 80s Hi-Fi Answers (England) had an article where they suggested removing the tantalum I/P caps in the Naim power amp (mentioning that you will void your warranty!) but the sound will be much improved.
All the best,
