I use an Audio Space AS-3i with EL34s to drive my Titus Es pair. You can also get a KT66 version.
Various tweaks can make this combo sound very nice indeed. NOS driver tubes, Herbie's tube dampers and Iso-cup footers, a premium AC cord, an isolation transformer. These all contributed to clarity and timbre right down into the bass, but the two factors that seem to have touched bass the most are the stands and the choice of speaker cable. I am using Audioquest Type 4 partly because it does bass.
So yes, you can squeeze more bass out of speakers with limited bass response. It's a question of optimizing setup and tweaking. Perhaps for that reason you might choose to go the KT88 route, but don't reject EL34s out of hand.
