It would be helpful for us to understand more. Preferably the components and venue.
For ease of communication I would use the terms phono stage, and preamp. If a preamp has a phono stage… that is a preamp with a phonostage. In integrated amp is a preamp + amp unless it is additionally designated to also have a phono stage.
While you can probably safely plug a phonostage into an amp… since the output will be low. If you are interested in the quality of sound, then a high quality preamp is probably required.
