Well engines do require break in and how you break an engine in will define how it works or lasts in the future. A fast break in usually means a faster, less reliable engine. A slow over time, reduced RPM break in usually means a longer lasting engine, with tighter tolerances, but a little less willing to rev freely. A compromise is usually best. A break in period that sets the compression rings with undue friction and heat changing other critical components.

What I worry about more is not the initial break in of the 950, but having it and the other components in a closed AV rack were the heat can get higher than sitting out side of the AV rack. This, I know, is outside of the original design specifications. I feel I need to circulate more air in the AV component rack without drawing dust into the cabinet. Any suggestions?
