@ papyneau I guess you will need to decide if you are going with an integrated or not. My personal opinion is the preamp is more important than the amp since it’s closest to the source. I also believe in system matching with separates i.e. using the pre and amp from the same company. Just my preference and you may have good luck using different manufactures but it takes a fair amount of experimenting.
There are some good suggestions on the integrateds. Luxman, Krell, Simaudio, and another one to consider would be the Coda csib. I don’t have any direct experience with Coda but they can be configured in class A and A/B and have been reviewed well. I think at this price point an integrated can provide a better value with a single chassis rather than getting another "box". Of course you lose some flexibility but perhaps not sonics. You won’t really know unless you can listen to the contenders in your or a similar system. Just my two cents.
