I've owned both of these woderful amps and can only say that it has to come down to your own personal taste. I found the 432 easier to listen to for long periods. I never grow tired and want to listen to more. I did find the krell to be more bam brighter a little more slam than the 432, but I don't like too bright and can find it tiring. So The smooth silky sound of Brendel or Horowitz playing piano on the 432 is heaven. The Krell was great but the Levinson is smoother. At low dbs the detail is more evident with the ML
