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.

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.  
It’s impossible to say whether what you are hearing is “normal” or indicates there is a correctable problem in your phono stage. This is because we don’t have adequate information regarding the gain structure of your system, your cartridge, your amplifier, your speakers. However, solid-state guys may resent my saying this, I have often heard the sort of low level hiss you’re describing to emanate from a solid-state phono stage set at high gain or wide open. I would call it “white noise”.
