Owning the DI upgraded version, I find that it is not lacking in bass in the least bit. It could be a bit more defined (upgrades will take care of that) and there could be some refinement that @grannyring mentions but all in all the DI's are very responsive, neutral and transparent at every level from top to bottom. Running 55 watts tube amp has more than enough power at any volume. Soundstage and detail are magnificent so I am guessing I would ask what components are not really giving you what you want in your sound?
