Calling All Analog Gurus! What to do about my vintage Signet TK7LCa?



I just took a chance on buying a Signet TK7LCa cartridge on eBay to try with my new Allnic H1201 phono stage. I got it yesterday, checked the stylus (looks straight), and mounted it on my Well Tempered Amadeus. Unfortunately, the sound is dull, dull, dull regardless of what settings I use with the Allnic. I cleaned the stylus, so that is not the issue.

Am I correct in assuming that the stylus is just worn out and will need to be replaced? Are there other things I should try? What are my best options? What would you do?

Thanks in advance for any and all helpful tips. I continue to have high hopes for this cartridge despite this inauspicious debut.

Walter, if you bought the cartridge on the 24th, we at least know it is an actual TK7 stylus and not a aftermarket stylus. I would set it up with a positive VTA. Butt UP, cartridge down. 

The Signet TK7LCa is one of my favorite MM cartridges, and maybe your stylus is worn, but I do remember several  people including the former MM guru turned digital fan, Raul, saying they did not like it, and used the term "Fumigate" to describe  it. I think if you are used to the sound of most modern MC cartridges, it will sound dull. 

So work with the VTA and if you still don't like it, have it looked at by a cartridge rebuilder and go from there.
