Hi there and thanks for the replies,
I have spoken to the girlfriend and it turns out that when she was at school in 1986 she saw a film that captivated her. She has started up a fan club, opened up an online page and collected a lot of merchandise including the Japanese and German versions of the film, which are exaclty the same...just dubbed. Anyway, during the pivitol scene of the film there is a dance/party scene where a TEAC A-2300SD is featured supplying the music. She wants one of these players as it featured in the film and only wants to use it to play the soundtrack back. Not sure how she is going to get the soundtrack on tape, but I was told that was for her to worry about, and she is very resourceful when it comes to that movie.
So, it has to be a TEAC 2300. However, I have managed to talk her into being a bit flexible with the model. I am assuming that the 2300 S was the base model, and has been mentioned previously the SD had the Dolby option. What I am wondering is what made as SR model a SR and what made an SX a SX model. If the SD is the only player with Dolby, did the SR and SX only have one extra feature than the S and what would these differences be? Also, if there a particular model that commands a premium for some reason.
Thanks in advance.
