Why manufactures donĀ“t burn in their amps and ...
Most factors/dynamics(with the exception of speaker system drivers) that are involved in "burn-in" will also diminish with idle time, and require another burn-in period. If a manufacturer turned out 2000 amplifiers, and ran them the 200hrs, to the... 
110V or 120V for Power Conditioner?
You won't hurt anything by trying both, and listening to each for awhile. You might find your system somewhat more dynamic with the 120V setting.

The companies I'm referring to test every driver for consistancy/tolerances, plus match the drivers for use as pairs. BTW: What you just posted as Bud's actions concerning the source and quality of his drivers confirms what I said of, "most higher...

Any aftermarker speaker reconer(unless an authorized warranty station) will be using Waldom parts with which to affect the repair. Your speakers will never sound the same(or even close) if this course is taken. Unless you replace the driver(it's n... 
Dahlquist speakers
Most of the opinions you'll get will be from those having listened to the Dahlquists almost 30 years ago, and playing with the equipment and cabling of that decade(obviously). Very doubtful that they can actually compare what they heard then with ...
