Herron VTPH2 questions?

Are you presently using a MM cartridge that provides a higher output? If so, let us know its output rating, and give us some idea of the highest position at which you normally set your volume control. For example, if it is a rotary control its minimum position may be 7 o'clock; its maximum position may be 5 o'clock, and the highest position you normally set it to when playing records may be 12 o'clock.

Then, with no music playing, try to determine how much further you can turn up the volume control (e.g., what clock position you can turn it to) before hiss levels become objectionable, or you reach the maximum possible setting (whichever occurs first).

You should certainly talk to Keith, but providing us (and perhaps him) with that information may also be helpful (if, as I say, you are presently using a higher output MM).

Thanks guys, just got email for Keith. He said 1.5mv falls between the mm and mc area so it may work on both but could also mean not optimised on both inputs!! I think I will wait for a normal Grado with 4mv output. Thanks.

Check out the Gain Calculator at the KAB website

I have two Grado Wood body cartridges, The high output Reference Sonata1 (5mv) and the low output Statement Sonata1 (0.5mv). The lower output cartridge is in my opinion light years superior to the high output version. If you can provide the gain, it's a great cartridge. The only problem I ran into with the low output Sonata1 was from my old phono stage (Grado PH1) which had too much hiss on the high gain setting while using any low output cartridge. I upgraded my phono stage to a Jolida JD9, which has much more gain, and is quieter too.

So if your Heron can provide sufficient, quiet gain, I think the low output version that VPI offers may really surprise you. I have no desire to listen to my high output Sonata1, it just sits there collecting dust.

I think Grado makes a version just for VPI that has more output than my Statement. It may also be shielded to prevent the hum most "non VPI" Grado's suffer when used with VPI turntables (the motors are apparently not shielded).

I wouldn't go with a high gain cartridge again, and the Grado version should work fine with most preamps. Just check out the calculator on the KAB website

I am using a Benz Wood SL which has a 0.4mv output and I have plenty of gain with the 69db that the VTPH-2 provides.

Now, I am using Clear Audio Aurum Beta which is 2.5mv output and my volume is on 9'oclock. If grado's out put is 1.5mv. Does it mean I have to move the volume up around 12 o'clock?
