Componentes antiguos que suenan mejor

Tal es el caso de este video que muestra un componente con partes marantz y que se siguen usando por su calidad, sin importar que tan antiguos sean.

Cintas de Carrete Abierto

Aparatos como este el Modelo 7, se vendían en los años 80, el resultado o resolución de audio que poseían estos fabulosos grabadores, era superior a los Decks, por lo mismo que era una fuente analógica, usaba cinta, pero mas ancha que la del casette, por lo tanto que a mayor espacio y velocidad el sonido era mas puro y con frecuencias mas altas, lamentablemente su manejo era un poco difícil, pues la cinta era delicada y era necesario saber bien como colocarla en el aparato, además sus precios eran onerosos, no al alcance de cualquiera.
