cartiage for Kenwood L07D genuine tone arm

Jagdzaku, I wouldn't let the stock tonearm discourage purchase of an LO7D. It is a superb TT, even without the arm. If you have access to a machinist, it is feasible to devise a generic turntable mount that will clamp down into the stock tonearm pod collet and accept pretty much any surface mounted tonearm(e.g. Dynavector, Trans-Fi, Talea, Kuzma, Schroeder.) I've had great results with Trans-Fi on L07D.

Jonnyb53,thanks for input. I have to admitted I did not considered it before
in some vintage preamp, there is a low frequency cut ( <20hz)；does it work?
Dgarretson，I will consider it on the second arm! :)

Jagdzaku,

Even if your phono preamp has a LF filter, an arm/cartridge combo with a native resonance of ~5-6Hz is asking for trouble. At a minimum, it would impair clean tracking and overexercise the suspension in the cartridge, possibly shortening its life.

Anyway, most LF filters do not operate as brickwall filters (unlike the HF filter in redbook CD players). SOME of that LF energy is going to make its way past the filter and into the amplification chain. At best, that adds sonic mud and raises your system sound floor. At worst, it may overstress amps or speakers.

Listen to Johnnyb53, he answered well.

Any and all low frequency "rumble filters" that I've tried robbed the musical presentation of a solid foundation and much of the life of the music.

Those LF filters were mostly for attenuating the "rumble" or motor noise of idler-driven turntables, and not for taming bad arm/cartridge mismatches, which can affect things (such as tracking) long before the result would reach the speakers.

I received it last weekend.
I found its sub weight should be attached to the arm for more choice of cartridges.
Does it change the effective mass of tonearm?
