Integrated: SS or Tube?

I'm currently using a Rowland Concentra II integrated, and while it's a great amp, I am wondering if I should go to a tube integrated amp. The Tenor is out, too expensive. The new BAT integrated tube is interesting. What about the Jadis DA60? Any feedback about this amp? I use the amp primarily for music.

Remainder of system is: 47 labs digital front end, silversmith digital and interconnects, analysis plus oval 9 biwire speaker cable, von schweikert vr5 hd speakers.

Thanks!
