@cleeds : You are argumentative because more than enhance our knowledge levels you want to " win ".
Who asked by digital/computer alternative? just argumentative.
In the other side I already listen the SG cartridge at least 3 times in 3 different systems and at least in two room/systems where you can only dream its very high quality performance levels.
Now, do you want to " win " ? I can help you: agree with you, you are rigth. Satisfied? Useless and futile to follow about.
