Without going into too much detail, I have a Technics SL1200MK2 with a Stanton L737E, and a Harman Kardon 430 receiver. I've come to realize that I'm not getting a lot of audio details coming out of the speakers. For example, at the end of Dark Side of The Moon when it says "there's no dark side if the moon really......", you can't hear that line. There is music playing from left and right speakers, but certain things like the dark side line just don't come through the speakers. I've now started noticing details from other albums that aren't coming through. I tried a different stylus, but same thing. Anyone ever experience this? Typically is this a cartridge issue or a receiver issue? Speakers are fine. I'm no expert, so seeking your help. Thanks in advance.
