If you think your system sounds great, why not just stick with it? Keep in mind that if you go with tubes, you may end up going down the "rabbit hole", spending countless hours and dollars looking to get the lowest noise and highest performing tubes. This is coming from a tube guy.
If you are still "tube curious", see if you can find a decent phono stage" that comes with a trial period. Modwright, Music Direct and Tavish Audio Design all offer trial periods (to get a taste of tubes)...as does PS Audio, but it’s not a tube design. : ) Good luck!
