Loss of volume

I recently moved, and now my analog system seems to be much lower in relative volume to my digital system than before. ....full volume on the preamp just doesn't seem nearly as loud as beforer. Any chance this is a problem with the tubes in my tubed phono pre? I'm baffled, and need some help.
its possible during the move the stylus got moved enough to not making proper contact ( just a guess )..If it where your tubes it wouldn't happen that fast and probably be in one channel only..Also make sure all your Phono amp connections are correct..Its easy to get a set of cables wrong when moving......Good luck
