phono preamp for Grado Master low output to C11

I use a Sutherland PhD and it really shines. With the Grado Statement1 at 500ohms input.

Grado's makes it own PH-1 phono amp that sells new for $500. It has switchable 40db/60dB gain

Your Mac C11 supposedly has "Voltage gain 20dB aux, 60dB phono". So let's see how this works out electrically...(experts please correct me if wrong, I'm trying this at 2am after a long night out)

Grado Statement Master @ 0.5mV x PH-1 @ 40dB gain = 50mV output x Mac C11 aux @ 20dB = 500mV output

Grado Statement Master @ 0.5mV x PH-1 @ 60dB gain = 500mV output x Mac C11 aux @ 20dB = 5000mV/5V output

I'm hoping that the volume control on the C11 attenuates the input voltage before reaching the amplifier stage. If so, on the 60dB setting things should work nicely with the volume less than turned up all the way.

I have used a Jasmine phono stage with great results with a LOMC Denon DL-S1. Second hand they sell for $450. On Ebay, a little bit more (this is where I purchased mine). These come directly from China. Read some of the reviews here on AG.

Second the Jasmine, much better than the Pro-ject tube phono box II with upgraded tubes (which was already pretty good to start with) and much much better than the Vincent Pho-8 two boxer. They are available from Amazon also.
