Budget Tube Preamp with Remote

I need a preamp with remote. My system is Adcom GFA 545ii; JM Labs Daline 3.1; Moon Audio 100D Dac; Onkyo NDs-1. I was interested in trying tubes. I'm replacing an Adcom GTP 400, and was thinking of something warmer. I listen primarily to classical and jazz. I would like to keep the cost below $600. Would an integrated amp such as a Jolida (using only as a preamp) make sense? Thanks very much.
