My turntable is a Micro-Seiki BL-51 with a Grace 707 II tonearm and a Signet TK7e cartridge.
I have the Signet TK7Ea, essentially the same cartridge in a different body. Signet or any Audio-Technica MM cartridge is notorious for being extremely sensitive to input capacitance, especially with 12AX7 type phono due to Miller effect. Make sure your tonearm cables are the low capacitance type. I made the mistake of not taking that into account and the sound became shrill and bright.....and I blamed it on the phone preamp! Oops!
