The series is changing, Music fidelity is a good company they make the HUGE class a amplifier , music direct has deals like this once and a while, I know of people who payed full price for that setup and love it, I have seen them setup as dual mono blocks, so some people think its good enough to spend $4K on, look on you tube there are some vids of how that dac works, it is awesome... If I had room for another system I would have bought that and another amp, that is 100+ watts per channel with the dac for $1500.. Pair them with a new pair of seirra 2's and you would have something special...
If you don't want to spend that much I would just build a system, use a sb1000, topping tp 60 or emo mini x, with a small dac and cd player, the sb100 will handle you sub and main crossing...
