Sadly no longer with us, I regard Russian opera singer Dimitri Hvorostovsky to be the finest bass/baritone of recent years, until his untimely death from a brain tumour in 2017 aged 55. Here he sings the well known and loved aria from Handel’s opera Xerxes (or Seres), probably better known as Handel’s Largo.
You've posted him before. That's OK. I find his voice too much just as I find Pavarotti's but I realise that I am in a peculiar minority.
