Thoughts on interconnect vs. speaker cable length.

Tpreaves, To help you understand.....
The OP is considering a shorter SC run and a longer IC run from Pre to Amps.
General experiences suggest that shorter ICs and longer SCs are the better sonically with all else being equal. Others more knowledgeable will chime in.

As Schubert offered, as well.

I prefer IC to be 1 - 2 meters, speaker cable 8 feet. Lots of opinions on this, just don't assume that shorter is always better.

I like my equipment rack at my side. Which creates the balanced IC between the pre and amp at (currently) 7 meters. It could be shorter, but with the extra length it can berouted to be unnoticed. My amp is between the speakers behind a chair. And the speaker cables are about 6 ft long.

Speaker cables should be fairly short. With balanced cables to amp the length of the wires from pre to amp do not matter nearly as much.
If i had to use RCa coax cables i would be making the pre to amp wires shorter, and could use 4 meter ones with them no so hidden.

The which os better short speaker cables/ short IC calbes has been discussed a LOT over the years. Used to be short speaker cables, long IC was the standard response. not anymore. Too many do the opposite to say one way is 'better' than the other.
Which basically means you can do what you want that sound better to you.
No one can make the decision for you. No matter what you choose, half will say the other way is better.

Thanks Schubert and Iso. To bring specificity to my question, I am indeed asking opinions on IC vs SC lengths for a run between pre and amp of 3-12 feet vs a run between amp and speakers between 6 and 15 feet. I am currently in position to try 8 and 15 ft SCs with 3, 6 and 12 ft ICs. Just looking for opinions and having fun with audio.
