Recommended loudspeaker cable for my Sonus Faber Guarneri Homage?

Guys, it happened that I found myself with old Sonus Faber Guarneri Homage speakers, Audiolab8000 amp set (Q plus 2xM) and MIT MH-750 speaker cables. Although I plan to replace amplifier a bit later, now I decided to start from selecting the proper cable to match my speakers, mainly because my old MIT's are too heavy and rigid (and probably not right at all for Guarneri speakers).
I would appreciate any recommendations on the best fit loudspeaker cable in my current setup, also being universal enough for further amplifier upgrade. Expected cable price range up to 5000 USD. Thank you all!
Thank you, alexatpos, for your helpful and very relevant opinion, I plan to keep speakers and go in the direction you advise.

I really like Acoustic Zen Absolute speaker cables (a silver copper blend) connected to my Sonus Faber Strads. They should be in your price range. I only needed 6' since my amps are next to my speakers.
GH’s are the main part of my system. IME, there are very few, if any, stand mount speakers that can compete with them. They are like a fine lens on a camera, everything that you change will be revealed.
I would recommend the best tube amp you can afford, GH’s love tubes..and cabling that is fast and resolving. Nordost is my current favorite in this regard.
Thank you, daveyf1, for supporting my confidence in GH's and agree that they help you to reveal every difference in sound coming from every system change you make. Will keep your recommendation in mind for my next upgrade from solid state to tube amp. Thank you for Nordosts, they are on my list.
