As I have double Schroeder Method running currently, I will be swapping their positions to see the effect. Swapping single ICs is efficacious, readily heard in a good rig, so I would expect the same with double IC.
shkong78, I thought you had used two sets of Schroeder Method ICs in your rig. Not sure if you swapped out their position, but you may want to consider it. Frankly, you would have to rebuild all the trials you did with double and triple again in the new positions. The results will vary for each one of those. Perhaps you already went through this, but most audiophiles miss this. Whereas most audiophiles are too lazy, or don't see the potential, you would see the potential and likely would have the zeal to try. :)
I recommend trying all compatible cables in all positions, even power cords. It's more work, but imo the only way to find the best expression of a system. :)
