Sony turntable makes speakers sound blown... but how?!

[jimginther]

First off, I know that by definition, a Sony turntable is never going to make vinyl sound spectacular, but as of right now, any records I play sound as though my tweeters are blown and anything with treble is very crackly.

Here's the part that I can't understand... how this happened after I moved, considering that there was never a problem prior to the move). While the wiring in the house is fairly old, I tried everything imaginable to rectify the problem. The turntable is hooked up to a phono preamp and then to a Yamaha A/V receiver using a standard line input. I've tried switching the cartridge, preamp, receiver (also tried on a Denon AVR-1706), cables, which power outlets the turntable/preamp use, and there is no change. I thought that maybe it was a grounding issue, since the turntable doesn't have a ground cable. I attached a ground wire from the base of the turntable arm to the chassis of the amp and there is still no difference. I've also brought the turntable into a repair shop 3 times and it worked fine there each time. Any other components that I use on the receiver sound fine.

I know that I'm not giving a lot of stuff to work with, but if anyone has had this problem or has any ideas, it would be greatly appreciated.

This is the part that does not make sense. If the turntable is faulty it should be faulty in different settings, to work at the shop and not somewhere else is puzzling. It seems you have eliminated most of the possible causes one by one.

Things to check.

Is the cartridge wired correctly, are all 4 wires secure, you may have a break in the tonearm wires somewhere which might come to light especially if you have moved recently if you have bare wire floating around inside a metal tonearm you could get shorting (?), cracked or chipped stylus on the cartrdiges woud cause distortion, incorrect tracking weight might do the same. other than that I am out, sorry.
