Phono stage inquiry


I have an upgraded Whest PS.30RDT & when I increase the volume on the phono stage input when nothing is playing to a level not too far beyond my usual listening volume, I can hear a hiss. 
Should it be silent? Do any of you have this with your phono stage?

Thanks for your time.

Phonostages with SUT for the MC gain are normally super silent (if grounding is taken care of). Active stages can have that mild hiss.
Thanks for the replies guys. It's good to know it's normal... so it's the design of the Whest...?
@yogiboy what is your phono stage?

Thanks Bill.

Thanks for the info Steve, I'll try that.
I disconnected my tonearm cable from the Whest & the hiss is still present. Also I didn't mention that with the hiss there's also a mild hum. The chassis of the Whest is grounded.
Also when I disconnected the XLRs from the Whest & increased the volume on the phono stage input I could hear my CD transport playing.

I have this Quicksilver Audio tube phono preamp!

I have a Herron Audio VTPH-2a that is dead silent, even on the MC side.  There should be NO noise from a phono stage at slightly elevated listening levels.  If there is, it's either a bad unit or it's a bad design.
