I too usually recommend Audience AU24 ICs but for your price you may want to try the less expensive Conductor series of Audience. They are supposed to offer similar tone but not at quite the refined level the AU24 has. BTW in my system the AU24 is very close to neutral, more so than any other cable IMO. Also Acoustic Zen Mat Ref MKI go for about $150 and is a very good cable for that price.
Also I am under the impression the Hero IC is a little warm but who knows? Also I am not very impressed with Cardas, too slow and sleepy for me as tried in a few different systems.
For speaker cables I usually recommend Acoustic Zen Satori or Hologram in your price range. Also Alpha Core Goertz MI2 speaker cable is terrific with beautiful tone. I think it is impossible to get totally neutral and all these cables have a tone of their own, just ones that I like.
all the best,
Phil
