Which is better as a PrePro: 1056 or 1066?

Assuming both costs the same, which is better to use as a pre-pro with a 1075 amp?

I'd take the 1056 any day. I've owned both the 1055 and 1066 and in my system when both used as pre amps the differences were so subtle as to be a non factor. The true pre amp would have a lower noise floor on the bench but in the real world the added features on the 1056 easily make it the smarter choice.

What are the advantages of using the 1056 over the 1066? What are the advantages of using the 1066? I'm guessing the 1068 would be a better option over both of these?
