Jsman, I used to own a DV 20X 2 (H). Traded it in for a Lyra Delos. I loved the Delos so much, I wound up traded up for the Lyra Kleos ... which I love even more.
IMO, the Delos does a lot more a lot better than the DV 20X2. I think the Delos' output is .6 mV. Not sure how that will integrate with your preamp.
Also, you should confirm that your phono pre's loading is compatible with the Delos.
Good luck.
