Ya es de madrugada, tras ver este Spectral puedo decir confiado: muy buenas noches.
Increíble reproductor de CD, descomunal. A mí que me disculpen, retrógrado o anacrónico no importa el adjetivo, pero en plena era de los servicios de audio (post descargas) y del tan mencionado HD (aún por comprobarse) yo sin duda alguna preferiría poner un reproductor como este en mi sistema y escuchar discos, es un pequeño monumento. No ofrece tonterías innecesarias, acabados de "dandy" o "playboy" ofrece lo que debe ser, ingeniería y refinamiento que descuella, impresionante en todo ángulo de visión y seguramente al oído, si no que desperdicio.
Admírenlo, Spectral SDR-4000SL
