Funny, I had the same question about a year ago. I have the same Krell 400xi and went with the Vienna Acoustic Beethoven Concert Grand. They went a little lower than the Baby Grand but still very much the same sound. They're a tremendous match with that specific amp. I listen to classic rock and jazz. The pair work together very well and while they sound great at medium levels I enjoy it loud when the situation permits and you if want to get that from this set up, you can. At high levels the music doesn't sound compressed. It pulls you in and holds you there. I heard three of the four speakers you mentioned. I didn't hear the VR-4jr. The ones I did hear all sounded very good as I'm sure the Von Schweikerts do as well. Having that same amp and after owning the VA's for a year I can tell you I'm really pleased with my decision. Looking back on it I'd also have to admit that the physical looks of the VA's probably swayed me as well. The build quality is superb. If you have any specific questions about the pairing feel free to send a note.
Lastly, as good as they sounded out of the box they're much better now that they've broken in. It really is a noticable difference.
Enjoy the hunt.
