How much $$ do bells and whistles add to preamp?

Hi All, I’m looking for a new preamp, but I don’t want or need things like home theater bypass, streaming, DAC, headphones, etc. Just a great preamp (maybe with phono). I’m looking at lots of models (Like Classe, Wyred4Sound, Peachtree, etc.) that come with lots of extras, and I’m wondering how much of the price devolves to those add-ons that I don’t want. Any feedback will be greatly appreciated, as usual.
