If you are going to use turrets try and get small ones, not those "forked" turrets normally seen in guitar amps. Reason for this is that smaller allows for easier soldering, components like some types of caps sensitive to temperature will get less heat, soldering will be more reliable, shorter current loop is very good thing too. Just look at how V72 was done for example, they could put 4 channels in 2U rack and still have some space left, with all precautions about interferences taken care of (no parallel wires where not needed).
Maybe connections look long because of pic, short current loop is good thing not practiced often enough in p2p builds.
