Vandersteen Treo CT, which can be placed very close to the front wall, or its bigger brother the Quatro CT (or even the Kento, but $$$$) . The Humboldt is a superb integrated, I’ve read, and the question is whether it would work with the high-pass filters that the Quatro CT requires (and that’s why separates are more ideal with the Quatros).

Quatro Wood CT
"That's primarily what I want from a pair of loudspeakers—not deep bass (which these Vandersteens do have); not wide dynamics (at which the Wood CTs excel); not clean, uncolored mids and highs (something the Vandersteens readily offer); but a stereo virtual reality engine to connect me with the music I want [to] listen to. On that ground, a pair of Vandersteen's Quatro CTs scores big-time." ~
