Best way to set gain

My new system consist of Accuphase; A-70 x2, C-2850, DP-720, DG-58, with ASLC-15 x4, and AHDL-15 x2 front end. With Martin Logan; Renaissance ESL 15A, Sony; HAP-Z1ES and Torus RM 75Bal. My question to members is what is the best way to set the gains on the amp and preamp. Which is to say should one set one high the other low such that at mid volume setting is at the level I would normally listen to. Or should one just choose settings that do not over drive the amp when at max volume. In which case should one just select gain settings the same on both units that will not overdrive amp. Opinions welcome.

IMO, A preamp will always sound better when used at the upper range ( past 12 o'clock) on the volume control.

Yes would have thought more swing if you will, less constrained, more dynamic. Your thoughts on best way to break-in new system. Loud and hard or slow and easy. Still liked what tecknik had to say and I thank you yogiboy for your post.

The Accuphase well take 600 hours to break in, its a slow painful journey but between 500 & 600 is when you start to say WOW. I used CasCade burn in about 250 of those hours and let it run 24/7 mostly and then started turning off the preamp a half dozen times to let the caps expand which helped. Accuphase recommends the pre at 18 db & amp at full gain so its up to you on which gains sounds good and the knob at which position to accomplish this. The AVAA is very good and its not a digital so having it at noon to hear more swing so to speak would make no difference.
Check out AA they have a whole section of Accuphase devotees where you can learn more about your Accuphase components.
