I am not familiar with that particular test record, but I would try to come closer to passing that "Torture test". Ignore any and all manufacturer's recommended VTF and anything you have heard anywhere about what the ideal VTF "should" be. Increase the VTF .1g at a time and listen for an improvement. Usually .2-.4 makes a noticable improvement. All styli are not absolute identical. Some may sound better a little over the recommend norm, and some may actually sound better a little under. When you get a replacement you will need to play around and find the best setting again. And keep that tip clean! I recommend Oznow. Any yeah I would not go and get some 8000.00 speakers anytime soon if ever. Make the most of what you have now before spending big on more components. You may find that only spending a little bit can be a noticeable improvement.
