I considered both models before buying my Dodd 120 MK II mono blocks. Mine had the cap upgrade already installed.
I am quite pleased with them. near Dead quiet... hold bias, and sound super. Quick, honest, and reliable.
Manley, Dodd, and Cary all have good customer support. I almost went with the Manley's, but the Dodds came up for sale here and presented a far better value, and oh yeah, some more power too.
Good luck.
