Integrated for Vandersteen 2ce sigII

Open baffle needs power.
To me they sounded very narrow or no soundstage at all with Belles 150 or Bryston 3b-st -- both over 100wpc. Macintosh MC352/Audible Illusions Mod3 pre did good job on these.
Tube amps on these normally OK only for chamber or symphony music. For rock or electronica they'll be very slow or require some room tweaks to compensate.

In low-powered setup listening to dynamic funky music such as Stanley Clark or Grant Green, I found that speed isn't there. I expected that the driver should stop after the drum beat or the bass slap, but it didn't. 
For the same price (+ a-bit extra) you pay for Marantz pm8004, you can get much more powerful Sansui G-9000 vintage receiver that compares to that little Marantz as BMW M-series vs. Mitsubishi Galant. Moreover, compared to this modern and cool Marantz that may go bad after just few years, Sansui is serviceable unit that will only go up the value and not down.

sbank,
excactly at AudioConnection Verona NJ I was not impressed of Rogue/Vandy combo for the reason I described with all due respect to John Rutan...
He also demoed them with Bryston amps which was a-bit better. 
Speed for me was very important factor since I mostly listen to instrumental music rock, jazz, electronic and classical.
