One innovation was the front-loading arrangement. Pioneer's angled cassette bay and the exposed bays of some Sansui models eventually were standardized as a front-loading door into which a cassette would be loaded. Later models would adopt electronic buttons, and replace conventional meters (which could be driven over full scale when overloaded, a condition called "pegging the needle" or simply "pegging") with electronic LED or vacuum fluorescent displays, with level controls typically being controlled by either rotary controls or side-by-side sliders. BIC and Marantz briefly offered models that could be run at double speeds, but Nakamichi was widely recognized as one of the first companies to create decks that rivaled reel-to-reel decks with full 20–20,000 Hz frequency response, low noise, and very low wow and flutter.
