Wait until you choose your amp (at least...maybe when the rest of the system comes together as well) as it's the pairing of the amp and speakers that you want to focus on. The Audio Note cables should be perfectly fine for the present. I've owned several models of Harbeths and always felt that they are less fussy about upstream components than most other audiophile speakers. Not that you can't hear differences, just that the differences between components are less noticeable.
I'll add that I think some of the components you are looking at (e.g., Pass separates) are overkill price-wise for your Harbeths. Just my opinion of course.
