Do I have to brand match preamp and amp?

I recently got an Ayre v-5xe Amp for my two channel setup (with Revel f208 speakers and PS Audio Directstream DAC). At a good price locally.

I looked at the matching K-5xe MP matching preamp, but it’s too expensive brand new and nothing available used.

Do I have to get a matching brand preamp? Or something different would do. My budget for the Preamp is around two grand.

thanks!
