The sonic effectiveness of modern low cost lightweight
receivers gives the lie to the theory that home audio gear
has to be built like a masonry commode to sound good.


It sure helps. If weight is not a big issue, such as if it were on an
airplane or even a car, a heavy unit is less expensive and longer
lived-one can overspecify transformers, put in bigger caps, use a
heavier chassis.
