Der MDS-JA3ES ist der erste SONY Minidisc Recorder für die Hifiisten mit höheren Ansprüchen was die Gehäusequalität und Wandlersektion betrifft. Waren die bisher überwiegende Anzahl der Minidisc Geräte mit Kunststofffronten versehen, hat dieses Gerät deutlich mehr Metall.

Leider leidet dieses Gerät (wie auch einige der Nahchfolger wie JA50 und JA30) unter einer Fehlkonstruktion des Laser Pickups. Dieser wird gerade im Aufnahmebetrieb mit einem zu hohen Laserstrom angsteuert. Daher empfiehlt es sich diese Geräte, wenn sie denn noch funktionieren nur für den Wiedergabebetrieb zu verwenden.

Im Gerät verbaut ist der Laser KMS210 und ein hakeliges Laufwerk. Ordentlich gewartet verrichtet es aber seinen Dienst. Viele Nutzer berichten darüber, der JA3 hätte den bestklingensten Wandler, andere schwören auf die umschaltbaren Wandler des Nachfolgers JA30/50 in der Position "Spline". Aufgrund der Laserproblematik sind viele dieser Geräte heute nicht mehr funktionstüchtig. Die Laufwerke im JA3, 503, 303, JA30, JA50, Kenwood DM 7080 und 7090 sind identisch. Dies bezieht sich nur auf Laser-, Antriebsblock und BD Board, nicht jedoch auf den Lademechanismus. Der ist nur bei JA3 und 303/503 gleich.

Remarks[edit]

  • The MDS-JA3ES is the first SONY Minidisc Recorder for the Hifiists with higher requirements concerning the housing quality and converter section. Were the so far predominant number of the Minidisc devices with plastic fronts provided, this equipment has clearly more metal.

Unfortunately this unit (as well as some of the close followers like JA50 and JA30) suffers from a faulty construction of the laser pickup. Especially in recording mode the laser pickup is driven with a too high laser current. Therefore it is recommended to use these devices, if they still work, only for playback mode.

  • In the device is the laser KMS210 and a hakeliges drive. Properly maintained, however, it does its job. Many users report that the JA3 has the best sounding transducer, others swear by the switchable transducers of the successor JA30/50 in the "spline" position. Due to the laser problem, many of these devices are no longer functional today.
  • The drives in the JA3, 503, 303, JA30, JA50, Kenwood DM 7080 and 7090 are identical. This refers only to the laser, drive block and BD board, but not to the loading mechanism. This is only the same for JA3 and 303/503.
