Is overloading of a preamp volume dependent?


I have read that if a phono pre signal is overloading a preamp, it should be independent of volume. Does this vary based on the preamp's architecture or is it always true?

I have an EAR 834p with 70db gain on its MC stage, going into a Thor TA-1000 preamp. I am hearing crackly distortion only on loud transients such as loud piano strikes, etc. It seems to be there even when I don't have the volume up loud.

Thanks for thoughts.

The louder the signal from a phono cartridge, the more likely it is that the phono preamp output will overload the line stage, regardless of the setting of the line stage's volume control. But you won't risk such overload if you choose the right selections of cartridge and preamps and - if the option is provided - the correct gain setting on your phono preamp.
