Some of the denial is probably solely an intention to be deliberately & provocatively contrarian and 'edgy' on forums and elsewhere. 
Some also advocate the use of bent coat hangers as interconnects & lawnmower flex speaker cable.Ermm

Many electromechanical systems must be energised or operated for a certain period of time before they reach an optimum and consistent output state. It is simple physics/kinematics; I do not work in any professional field but the rational side of me accepts this as fact and I am confident that experiments could be devised to validate the existence of a "run-in" period.

From a newly powered-on electrostatic speaker panel to brand new shoes on a person's feet, it is obvious that materials undergo changes through use. Those that cannot contemplate this are like "flat-earth" believers that refuse to consider the possibility of a round Earth even when presented with plentiful evidence that supports a new principle. Cognitive dissonance and bias. You cannot reason with that kind of thinking.

No, just ill founded and overbearing opinions.

As to the question of pre-burned in equipment, I would rather hear the burn in process for myself. It's all a part of the enjoyment of our pastime. The loan scheme equipment provides the opportunity to hear burnt in units with no obligations, apart from returning it, that is.

Just listen, if it sounds good to you, enjoy it.

Time left powered on is part of the "burn-in" process. After quite a bit of use from new, the electronics improve from their "brand new state" but will not stay in their optimum state once powered down for a considerable period of time and will have to be powered up again for some time until they return to the optimum state. It's based on capacitor charging/discharging and stored energy held within the electronic components. I would envisage that they could influence impulse/phase response and distortion audible in signal reproduction.

From new, the electronics probably takes a few weeks to reach optimum charged stable state but after this period has passed, the power-on period needed to restore the charged stable state is probably reduced to a few days, depending on how long the electronics have been off.

The Reflex M on the European loaner scheme has been well and truly run in.
I am happy to help if you want to borrow something.
