Pros and Cons of using same brand IC- please


Hi, I have been using same brand IC.(harmonic tech-TruthLink ) for CDP to Pre and Pre to Power amp.
I read few website reports that 1 pair is good but 2 pair is'nt as good (for such applications);just wonder do you confer such findings ? Whats the reason behind it ?
Your explaination, opinions is eagerly needed and thanks in advance

Thanks S23chang.
My less refined IC is Chorus-Straightwire( GOOOD Bass , strong mids ),while TruthLink is BIGGER (+ 25%THICKER gauge)- supposed to be HIGHER Copper purity ,cost almost 6X more $ .
Whats your suggestion then ?- should Chorus go CDP to Preamp ? or Pre to Amp ?
Thanks in advance
Simon
Try either way and see what sounds better to you.
When I said thicker gauge, I mean the strand wire ( not the whole cable itself.) If I have more choice, I would get rid of the Chorus and get something else for the CDP to preamp.
