I wish to discuss a little known fact which goes far to eplain the build quality and sound of this player. These "gold" ES players from the late 80's thru 1995 were essentially units designed and built for the home Japanese market. Their sound was voiced for Japanese preferences, i.e., harmony and tone rather than American high-end preferences, i.e., analytical detail often accompanied by tonal sterility. It's no accident that so much old McIntosh and Marantz tube gear has been exported to Japan.
In any case, because of the small volume of sales to the US, Sony simply took their domestic units, changed printing to english, adjusted the AC line voltage, and gave us the "gold" ES players. In direct comparison the the best domestic and English players, these ES players have an unmatched full tonal quality and "naturalness". Just like tube equipment, however, they lack the pin point detail of top end transistor equipment. So if you're an engineer conducting scientific measurements these units are not for you; but, if you're a music lover, who simply wants to experience the full emotional involvement with the music, these units are unsurpassed.
In addition, considering their build quality, at their current used prices, they must rank as one of the great buys of the music equipment world. And no, I'm not getting ready to sell my unit! I simply wish to share my opinion with other music lovers on a budget.
