Any Sound Difference bw Tandberg 910a 3014 3014a ?

Besides price whats the sound difference and quality between Tandberg 910 3014 and 3014a the two tanbergs? and whats so special about the 910.

All Tandberg 3000 series models with "A" are sonically improved over the same model number without the "A".
3014A compared to the 3014 has more sophisticated recording and output circuits and better parts such as polystyrene caps and close-tolerance resistors in key sections of the signal path. I have never compared these 3 myself but I can tell you my 3014A is a keeper.
