Cable advice needed

Hi Audiogon Community:
I'm switching out my rca cables for xlr. Which IC's do you recommend going from CD Player to Preamp and Preamp to Amp.

The  IC's xlr I own are:
Purist Audio Design Venustas Praesto Rev &
Purist Audio Design Proteus Rev A

My system :
Ayre Acoustics CX-7eMP
Belles Aria preamp
Maker Audio G7 Amp
Tyler Dx2 speakers

Thanx so much for your advice

That's what I got out his question also.
I agree with jl35, "most companies recommend the best cable from source to pre." I have two different XLR cables and use the "better" one between my source and pre.
The rationale would be that the more "delicate" signal is coming from the source, so use the better cable there, as others have already said.
My experience different,source to pre amp which is in line with the philosophy of Dr.Ono.
