Preserve Golden Referance sound add Netrual Ref ?

Thanks to everyone for your advice.
ICs are balanced. Teac Esoteric X03 and Droplet CD players are connected with 2 pairs 1 meter Golden Ref to Bat 51 se pre. 4 meters from pre to Bryston crossover, 2 meters to non-bass BAT 150 SE amps and 2 meter to bass Simaudio W10 amps. 2x5 meters speaker cables to Magnepan MG 20r. Cables are all Tara Decade.
The Golden Ref makes a change in the music that I really like:
By adding more Golden Ref , I am concern about the 'additive effects', in other words I would prefer to create IC chances between the CDP and pre, since this is the shortest run and most economical.
John, thank you.

Thank you for all your response.
After several days and hours of listening here is what I have found in my system as many of you indicated.
Connected between CDP and preamp is a 1 and 2 meter pair Golden Referances at different inputs at the preamp. Both cables sound different. The 2 meter tilts up the bass notes that it is not listenable. The 1 meter sounds the best. However I do prefer the 1 meter Netural Ref over the Golden Ref.
And as you guess, the 8 meters NR run from pre to crossovers to power amps creates outrageous bass which is no good. I think this is additive effects.
Replaced the 8 meters NR with the 10-12 years old Tara Decade brought everything to normal again.
It now appears to me that I should only change the IC between the CDP and preamp to gain controllable changes.
What I have learned now is that each different lenghts of IC will change the sound and seems to me that the IC are sliding knobs on an equalizer.
Thank you again.
