I’d consider some tube rolling with the AI before giving up that preamp.

Definitely stay with tubes if a Krell 350 watt amp can't do low end it's on the amp not your preamp. Are there better tube preamps than the AI? Sure do you have a budget in mind?

Backert preamp as superb.

Funny this post came up, wondered when it would again.  I just spent the last 90 days re-evaluating my SS preamp to my 6SN7 based tube preamp.  Both are nice in different ways, however nothing about the SS preamp can replace the sound stage, layers, 3d imaging of the tube preamp - IF that's what you are going for.
