YW Shaizada, you've got some esteemed company in your Audio group. Bob L knows his stuff. Leif spends a lot of time tuning his speakers to get the sound he wants, and so to me there is no point in upgrading the internal wiring for example. Theoretically using the same wire internally as your speaker wire & ic's would improve coherency, but might upset the overall balance of the speaker which as you said, would have been tuned using Jorma No.2 in this case. Good show!
