Jalen- I had a C38 (among others) for a while which is basically a simplified C40 and found it to be very good but not quite as transparent as my C712. The C712 mates super well with my MC7100, not to mention they are in the same chassis which looks great as a stack. The C712 is the next generation after C38/40 and so perhaps the C45/46 are better than the C712. I have yet to hear these new ones. By the way, I love my Mc7100.
