this is in my opinion one of the great animes of all time, if not the greatest.
The compression on the dvd's audio according to some sites though says are not As good as the re-issued laser disc box set or movie box set. If I had the equipment i would definetely do transfers of the lasers.
In fact there are a lot of anime laserdiscs that need preservation being as the dvd releases are inferior in most cases or changes have been made.
