Looks like your front to back separation may need further adjustment, when you get your Fisher disc adjust the signal with the front channels turned all the way down and adjust the separation control until you can just barely hear the tone. Don't forget that you are not going to achieve the kind of separation you are used to with digital media, with analogue sources you should expect anywhere from 20-30 db, depending on the cartridge. This means that you may still hear some sound bleed, but you normally wouldn't listen to only one channel at a time. Now, I can't tell from the wave forms what you're hearing, but if you could post a a sample, I'd be interested in hearing how loud the sound bleed is. Also, don't forget that you are dealing with a piece of electronic equipment that is at least 35 years old and no doubt it may not be performing to spec. Let me ask you this: do the chimes seem like they are moving around you or does the bleed blur the image so much that you can't tell where it is coming from? Also, is the sound distorted? You may have a disc that has a damaged carrier signal, though in my experience that usually causes a "gritty" sound.
Thanks Quadjoe for responding. I have posted a DTS version in a previous post (although this was recorded with the Grado Cartridge - the AT12Sa is similar. Here is the link again http://sendshack.com/download/4htqi64
And regarding bleed - it bleeds very loudly front to back - even if i place the adjustment in the hardly audible range. I am going to say (although i can't really confirm) that it sounds like an SQ with a very early decoder with poor separation. Please, listen to my DTS sample and let me know..
Thanks again..
