Re: Turntable "upgrade" not living up to expectations?

Thanks for all the replies everyone.

I suspect the cartridge is simply worn out; in addition to whatever use it was put through by my relative it also sat unused for approximately a decade.

Careful cleaning of the stylus did reduce the distortion; now the PL400 and ATPL50 distort about equally now. Neither seems to do well with complex, loud passages.

The PL400 is definitely more musical. I suspect I'm now hitting the tracking limitations of a cheap factory mounted AT3600 cart. in the ATPL50, and the limitations of a worn-out cartridge in the PL400.

I checked the alignment of the PL400 with the free, downloadable protractor from http://www.enjoythemusic.com/freestuff.htm . It's actually basically right on. The VTA is not adjustable, as mr. bear pointed out. I don't have a VTF scale yet; I have it set between 1 and 1.5g right now, where the previous owner had it (after balancing the arm). I don't have the manual, and therefore don't know where to adjust the azimuth, but it looks fairly good anyway.

I also looked at the stylus tip with a jeweler's loupe that I happen to have around. I can't see any sharp edges/flat spots on the diamond, so I don't think it's tearing up the records I put it on at least.

Guess that just leaves me looking at new cartridges for this thing then. Do these types of turntables (quartz DD) typically have the infamous "Grado hum" issues? Aside from that the Grado Black seems to get good marks at its price point.
