Advice on cables for Tannoy D500 powered by Sansui au-317ii

What are you using now and what lengths are your current cables?
How many Interconnects? RCA or XLR? Price range? I have some ideas but need more data from you;>)

Thank you Tom for your help :)
I have the tannoys connected to the sansui with 2 cables of 4 metres of cheap QED (0,74mm2) white. They cost me 22€ or something in FNAC (http://www.qed.co.uk/speaker_cables/profile/qed_classic_42_strand_cable.html.)
My RCA interconnects for the CD are those regular red and white found in my house from other gear, perhaps with 60 cms (6€ maybe).
My old Philips turntable has its own RCAs.
Any ideas on how to improve?
Best

I forgot to mentioned that I intend to add to the system a chromecast audio (short cable with 3.5mm jack and RCA) and a 5 metres cable jack 3.5mm (male) and 2RCAs (male) to connect my macbook. Any hints on those?

TANNOY expressly recommends  Van Den Hul speaker cables with all their speakers. They even had their own TANNOY brand cables thst were rebranded VDH Inspirations.

 That's what they are internally wired with so it makes sense to continue the same sonic signature upstream.

Google which model has which level of cable in it.

thanks akg_ca. I will google those two hypotheses and report back
