Having gone from a solid state to tube preamp, I can say they will warm things up a bit, but if the problem is that your system is truly "bassless", I have my doubts it will solve all your problems.
I am going to go out on a limb here and suggest as a test that you reverse your speaker connections, on one end, for one speaker, and see if the bass magically comes alive. i.e. could one side be wired backwards, either internally or externally? Not trying to insult any intelligence(s), but if there is truly no bass on a set of speakers this size with these amps, it seems to me there is something systemically wrong. I have no experience with these speakers, and others say they are bright, but sounds like they are abnormally bright.
If that makes no difference, I saw an earlier question about the age of the amps, time to recap? Not sure that would cause the issue, but seems to me that the caps help provide the reserves to handle demand for bass. Not an expert here, but thought it worth commenting.
Hope you figure it out, lot of nice gear.
