@romyeo, I know it is tough but I'd suggest you wait for the 75.4.
It's less than a month away. And overall you save 3K for waiting,
and you get a really good amp in the bargain. As I love saying again and again,
all good things come to those who wait. You've built a good system over time. If you're going for the 60.4 and 300.1, ok -- you still get a really good setup. But
don't compromise for a lesser 4-ch amp now just to have your setup completed immediately.
My 2 cents
