Best Speakers for Symphonic Line electronics

Hi Turek -- I'm pretty familiar with the K250. In the absence of info on personal tastes, I can only offer general comments. So here goes:
The 250 can drive practically anything and I've rarely (if ever) felt there was a "mismatch" with the different brands of speakers I've heard driven by it. If anything, it was just the inherent "musical character" of the speaker coming out; one either liked the speaker in question, or didn't...
So it all boils down to:
a) the volume limits imposed by your room size and treatment...
b) yr tastes in reproduced sound, i.e. which speakers reproduce what you cannot do without and compromise where you don't really mind!

OTOH, I find (you're the better judge, however) the tube pre a bit on the warm side, stronger in the mid (& upper mid) region So, maybe, speakers that are generally termed as very "flat", "a bit on the dry side", etc, could also apply.

BTW, SL make their own speakers; 1-2 models sound beautiful (but they are expensive)!

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

Hi Turek -- I'm far from biz connections with the audio manufacturers! I met Mr Gemein of SL, talked about jazz & Brahms, tried his equip & liked the sound.
I also have a pair of RG & Kraft mono's at home. (I also have other amps -- this is a disclaimer)
As to speakers:
I admire the Vandies for their "correctness", but I'm not enamoured by the overall sonic result. It's a matter of taste, really.
For me, the Soundlabs are another matter. The big ones are magical (but don't drive them TOO loud with a 250 -- the 250 outputs lots of voltage when asked for, it could damage the speakers). The Belcanto are not that far removed, soundwise, from the Soundlabs. They have more dynamics, while the Soundlabs have better nuances, reminiscent of a "full-range" Quad.

You noticed my preference for stats. Take what I say with a grain of salt. Your 250 will drive them anyway, so it's up to your ears. Cheers
