engineers, and computerized automatic systems; and

it offers the portability that allows the system to be

taken out of the home and away on vacation.

Here at last is a "mini hi-fi system" that is perfect

consumer.

However, when it comes to quality of sound

reproduction, many of the new mini-systems fall far

short of expectations. For the portable cassette-radio

—

descendent of the 50's transistor radio — sound
