I'm getting a shed load of hiss on high end vocals and the like (think esses sounding like the snake on the jungle book). It's only on Vinyl.
The setup is a Technics 1210 turntable on a Yamaha A-S500 amp with bi-wired Wharfdale Diamond 9.1s. It's on a stanton D500 cart and the vinyl is clean (and the needle appears to be too).
I'm pretty sure I've done something daft though the arm seems well balanced and it's not a constant hiss and only on the high end range. Mid and low seems fine. If anyone can point out the error of my ways (no matter how daft it may seem), please give me a shout.
LGF, I had to retire my Rotel amp last year - they sound lovely but mine developed a static fault around the volume and Main/ remote switches. Switch cleaner didn't fix it
How old are your cartridges ? As moving magnet carts do wear out over time so a new cart and stylus may be worth a punt, for cheap try audio technica . Stantons have never been known for sound quality they are just hard as nails for mixing with .
One other thing to check is the four wires that connet cart to the headshell as they maybe a little slack
