Sfrounds,
I used to own the VK-30, I found with good NOS tubes I preferred the VK-30 to the 30SE version. I have experience with MANY 6DJ8/6922 subs in the VK-30.
IMO, based on what you're looking for, there are two tubes that will probably work for you. The first is the Amperex-Holland 6DJ8 Bugle Boys, you want the real deal, not the ripoff Richardson fakes. The Bugle Boys have terrific midband bloom and an overall "wet" sound, with a forward soundstage--it will correct for the flatness of your current sound.
The alternative are Mullard CV2493 gold pins, these are British military versions of the E88CC/6922. These Mullards also feature a very "wet" sound and are terrific, a little rolled off in the treble compared to the Bugle Boys, but an extremely lovely sounding tube.
I would also recommend you look into different cables, the Nordost is a terrible choice with BAT in my opinion. Look for some nice copper cables like Analysis Plus, Acoustic Zen, or Cardas to get you closer to the sound you're looking for.
As for power amps, there are better choices out there than the BAT solid-state amp for your Logans. Innersound, Belles 350A, Llano Trinity would be three excellent choices in the same price range....
