Is there any truth to this question?

Generally speaking, phase coherence without time coherence negates the advantages. Most speakers that are time and phase coherent tend to have impedance's that generally work better with ss.

Digepix, if you have a solid wall 3' behind the listening position, you might want to consider putting some absorptive material on that wall behind you, and moving your sitting position further back from the speakers. Not only will you get the rather considerable (with Vandersteens) benefits of driver integration and all advantages that come with it, you just might get better bass response at the listening position as well.

Unsound I'm limited to location, because I'm in an apartment and this is the only place that works and I'm also in a wheelchair full time. The absorptive material might work I have to look into that.

Unless there is something behind you, the wheel chair might actually be an advantage in this particular case.
In answer to your question, I'm not sure if the YBA or the Krell will sound better, but I'd think the Krell would work more effortlessly. If that effortlessness makes for better sound, only you can decide. I suspect it could.

Opps, hit the click to quick. I haven't heard the YBA's in some time, and honestly don't have a recollection of their sound. With that said, the Krells, have legendary tight bass, something that could help with the Vandys somewhat woolly bass. On the other hand despite claims to the contrary, the upper end of the Krells are not bright, in fact they're a bit dark. I think some confuse the bit of grain that Krells produce in this area with brightness. In any event, the Vandys can be a bit dark in this region too. So you might be concerned about doubling up on those traits.
