Listen to both if possible.
I would take the TAS Marsh review with a grain of salt (tho they also reviewed and were impressed by the McC) as they have also raved about products in the past designed by Marsh that I thought were disappointing, like the Monster power conditioner. Marsh used to work for TAS.
I'm not really suggesting an consistent editorial bias, just be aware that rave reviews are not a good enough reason to buy an amp.
