Looking for a phono preamp that has volume control

You can find many options and some good suggestions above.
I also have the PS Audio GCHP-(no idea what that stands for)
which I bought for $500 on Audiogon. Hell of buy by the pound.
Since we are only left to guess whether the OP means to spend 
$500 or $5,000 many of these suggestions are not going to work.

We don't even know what he's trying to accomplish.
Nice tries anyways.

Look at the Aqvox2CI. It has a balanced design all the way to the Cartridge and thereby provides the lowest hum and noise I have ever experienced. 

Graham Slee Accession has a volume control.

hi georgehifi
You're right about the vdH Grail.
Last year I auditioned nearly everything balanced in the £5k to £15k range.
Grail was the best by a long road.  It has everything, accuracy, soundstage, realism.
And it can be connected single-end or balance.  I noted many contenders are SE only when balanced is the clear best way to go.  I didn't audition any of those because my system runs balance from stylus to speakers.
