Which sound you want your system to be? That's the most important. Transparent is very good cable for Dynamic, warm and detail but not on all of them. I have a pair Transparent Reference MM and they sound very good to my system.
A friend of mine have very similar system as you have. He bought a pair of MusicWave as well and he put it on the side just after 2 days of used. MusicWave is a lit bit too bright. Specially when you play some of High Vocal Sound, It make you feel sick of the music.
For your system, I thick you should try Harmonic Technology Pro 9 Reference SE cable. It will make dynamic tight base and fix the sound of your KW-500 to be more neutral and soft because what I think Musical Fidelity is too thirsty on the music.
Hope this will help you for the choice.
