Not sure which Dynaudio speakers you have, but my dealer's setup with Lamm ML1/1.1 amps driving the Dynaudio Temptations is excellent, bettered only by the Siltech amps (and at $75K per pair, they're only a gleam in my eye!) and far better than any solid state amp I've heard at the dealer's, even the Boulders and the big Classe. You can probably get used ML1s and a used Lamm LL2 line stage in your price range (although I'd suggest springing for an L2 line stage if you could stretch the budget), and if you get a later production pair of the ML1's it'll be almost the same as the new 1.1 version. If your room is really big, the larger VTLs are also good and may be better for higher spls, just not as refined or natural as the Lamms. I find the Lamm equipment to be one of those rarities, components that are quite accurate, yet somehow excel at conveying the soul of the music.
