Herron VTPH2 questions?

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?

My guess would be more like 10:30 or 11 o'clock. The difference between 2.5 and 1.5 mv is only about 4.4 db. There may or may not be an additional 3 db of difference because different test standards exist, as discussed in this thread.

I believe that volume control rotation from 9 to 12 o'clock typically corresponds to a volume change in the area of roughly 12 to 14 db or so.
