Best Speakers for Symphonic Line electronics

Gregm,
I had the RG3 MK3, but much prefer the tube pre. The sound stage is broader, focus is better and it eliminated a harsh high pitch (I'm being very picky. the RG3 MK3 is a great preamp.)Also all music sounds more real now.
When I first got the Kraft I had Audio physics Avanti Century speakers and I thought it was a terrible match. They were very bright sounding and everything sounded kind of light weight. To remedy that, I bought the Gershman Avant Garde's (They are known to be non fatiguing - much better in my opinion). Now to me most music sounds natural and accurate.
I should probably leave my system alone, but I'm really curious how much better top notch speakers would sound.
Other than the Belcanto's, I'm considering the Vandersteen 5A or a big Sound Lab speaker.What do you think? would one of these be better than the belcanto's. Any other speaker suggestions? I'm looking for music to sound as real as possible. Not too warm or bright.
Just curious, how do you know so much about Symphonic Line? are you a hobbyist or are you in the business some how?

Thanks

Just wanted to thank everyone. I'll have to check into all of these speakers.
Gregm, Do you think the Audio Artistry Beethoven grands sounded better than the Belcantos with the Kraft 250?
