Once Class D is close enough in quality even some of the deep pocket Krell, Pass etc guys will switch.
Once that happens they will sell thier existing gear which will gradually bring the value of that existing gear down giving not so deep pockets the chance to own true high end as it exists today."
I think what you forgot to factor into this is if Class-D reaches or surpasses Class-A or A/B, then the prices for Class-D will also reach or surpass Class-A or A/B.
Some people may sell, but I don't expect to see pennies on the dollar. If so, I'll be the first one there to grab a pair of XA-160's!
