In Reply to: Turntable "upgrade" not living up to expectations? posted by Paul Keller on October 31, 2004 at 13:43:31:
Better resoulution has never made my old records sound anything but better- you're thinking too much! The PL-400 is a decent sub-$50 turntble IME. Check the basics:First, it sounds very much as if the cart is worn badly and/or misaligned. Don't risk trashing your records with an unknown old cartridge. Do the math: relative cost to replace that old Empire with a decent-sounding new Shure M70B or A-T CN-5625AL for $25, verus killing dozens or records! Check Needle Doctor, Ed Saunders on eBay, etc. for cheap deals and reliable service.(Go to your local HoFiHut- mine has carts in th little glass case for $30 to $3000, and they answer all qustions, dumb an smart.) When you get a better 'table, keep this cart as a back-up.
Mount the new cart and set it up decently- it doesn't have to be the National Bureau of Standards- you can do a good enough job. Look in VA FAQ- link at top of page. You want to set the tracking force with a scale, don't trust the numbers on the back of the arm. You can buy or borrow a friend's alignment protractor (commonly a mirored scale with calibrations printed on it) and make sure the cartridge is aligned as well as it can be on the arm, to reduce tracking error. Follow the E-Z instuctions with the protractor. Don't forget to look at azimuth (the twist of the crtridge about its longtitudinal axis). I don't think the Pioneer can be adjusted for vertical tracking angle easily, but read about it, look at yours, and think about it.
Clean all electrical contacts but be absolutely sure not to get contact-cleaner on the diamond tip of the cart- they can come unglued and fall off! Make sure the cart mounting screws are tightened snugly and the removable headhell is firmly attached.
Surprisingly, a major determinant for good sound is to clean your s records- some carts are more sensiive to noise and crud than others! I think its fair to say that cleaning in all cases improves the sound and makes your records last.
Good luck. Didn't mean to get too rudimentary- if you know all this already forgive me. Ask questions here if you get stumped.

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.
...1.25g seems a bit low. Too low a VTF can encourage mistracking and make records sound overly bright and harsh. Try it at 1.75g and see if the sound improves. This seems to be more or less the optimum weight for many moving magnet cartridges IME.Hope this helps!
