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

Take a look at the Aesthetix Pallene you can get it with line leveler or you can add a phono,DAC or upgrade the headphone amp you can add them at any time  I have one just with line level it is a new preamp for Aesthetix it is not on their web site but it is the preamp from the Mimus integrated amp a few of us on Audiogon have it

I guess I wasn't completely clear in my initial posting.  I'm wondering how much add-ons add to a preamp's price.  For example, is a $6K preamp with a DAC and streaming really a $4K, $4.5K, 5K preamp.  I'm asking just in case I find something I like but it has extras, I'd like to know exactly what I'm paying for.

I have to have remote, XLR in and out along with RCA inputs and outputs .   Bare bones other than that .   No internal DAC , would probably get an outboard phono stage ….

Do you want a classic stereo preamp or more of a DAC that serves as your preamp?   

Hard to answer your question but that’s probably a good guess of if it were not including DAC.  The thing about preamps is they are becoming more like DACs with volume and inputs   Some DACs even have analog inputs.
