  Any error in set-up, including marginal VTF can excite/exacerbate resonance.

  Good luck,

• 11Hz should not a problem, yes I read the posts below. - Garth 07:45:59 08/12/06 (10)

  Adding the weight at the headshell is as John points out the only reasonable way to change the masses, either consider it an increase in cartridge mass or arm mass...same difference.

  BUT ... with the combination you have 3 grams added at the headshell, which is not a small chunk of "stuff" will barely lower the RF 1Hz, namely to just about 10Hz.

  If the combination currently fails at 16Hz I doubt lowering the RF 1Hz will help much.

  Forget the test record for a moment. How does it sound playing something like say "music"?

  Perhaps you can't trust that test LP. It is one of the few I don't have.

  Good luck.

    Hi Garth,

    I forgot to mention that I also tested the Satisfy-Sumiko Blue Point

    Special Evo III some time ago and it also got passing grade. For the

    music of course the Stradivari beat them by miles, but at 14Hz it is

    very close to a low violin tone. Its one of those thing wherein we

    say what you don't know won't hurt.

      A double bass maybe. A violin's lowest fundamental is nowhere near 14 Hz, unless I'm sadly mistaken (a distinct possibility).

        The lowest note on a string bass is about 42-Hz, depending on tuning.

          19hz, the lowest pedal note on the pipe organ.

          My subsonic reinforcement delivers this and it puts chills up and down my spine listening to these type of fundamental notes.

          Cheers!

          I am busy burning those test CDR's I have promised.

              Dorian mastered some CD's with these big pipe organs. I wonder what they did with Red Book's 20hz brick wall filter? I don't have an oscilliscope to see what my copy hits as the lowest note.

              An HDCD, DVD-A or LP would have no problem hitting the 19hz note.

                  which is below the Nyquist frequency. The Nyquist frequency is 1/2 the sample rate and is the absolute max frequency that can be reproduced with a given sample rate.

                  It is more like 20kHz.

  resonance figure of 11 Hz, nearly ideal. are you sure about those figures?

    According to the Cartridge DB my arm/combo should have a a resonace freq of 9 or 10hz. On the HFNTR it comes in at 15hz...

    If my arm truly has a mass of 11g (nottingham interpace arm) and the Karat weighs 5.3g and compliance of 15, something doesnt ring true.

    I do love the sound, but if there is a warp on the record I do hear that energy coming out of my sunfire sub (xover is at 32hz) main speakers are Magnepan 3.6's

    I have thought about getting a 3g headsheel weight from VPI to see if that would help.

    Just have not gotten around to it.

    Any thoughts on the subject?

      In Reply to: My experience is similar posted by DKG on August 12, 2006 at 12:08:04:

      If it were too high there would be too little bass energy all else being the same.

    Hi Henry and Paul,

    
    My turntable is Ambient, so its purely Clearaudio. When I subjected

    it to Image Hifi Ultimnate pickup Test Record's tonearm-cartridge

    resonance test, the tonearm started to shake from 16Hz to 12 Hz and

    gave warbling sound. I was really disappointed since my other system

    which consist of Cl A Emotion-Satisfy-Classic Wood passed the test

    easily. And I'm sure the specs are correct.

    
    Best regards,

    Joseph
