BAT/Levinson/Aerial have good synergy. I owned 10T's and used 33H's with a VK50SE. You have a great system going there.
If you are happy with the sound without a preamp, then good for you, enjoy the music and pocket the savings.
You make no mention of the cables you used for the preamp when you had it to try. All of your current components will reveal all about the interconnect and speaker wire used, and show you nothing but the truth. At the level you are at any change in cable should be immediately noticeable for better or worse. This could be why the BAT preamp didn't do much for you.
Best,
Paul :-)
