Cartridge recommendation?

I am not familiar with your current cartridge or the other ones you mentioned.
I have Ace medium on my table and love the sound. It was a HUGE step up from the Sumiko Pearl I previously had.

Don't own the Telarc 1812 on vinyl....have it on CD and my player tracks it fine...no problems with cannon fire.
:)

I put a Shelter 501 mk2 into my MM7 and the improvement was substantial. A friend of mine put a Lyra Argoi in his MM7 and I think that is even slightly better than the Shelter. I know this because he brought his table over to my place and we A/Bd both MM7s directly in two different systems I have.

hello:

If it helps, one of my turntables is the MMF-9 with the stock maestro cartridge. I have 2 Lps of the Telarc 1812. One Telarc tracks perfectly all the way through...the other "throws the arm" at the cannon fire. I have not had time to experiment with gram weight adjustments yet on the 2nd one.

Furthermore, I have read that the Dynavectors "ride a bit deeper" in the groove, but have not personally tried their cartridges yet.

By the way, arresting the tracking problems on this Telarc it is a worthwhile pursuit....

Good Luck.
