I have owned a pair of Olympica Nova Vs for about six months. They constantly surprise and delight me. I upgraded from a pair of Goldenear Two Pluses. Big jump in price, but also in quality.
I think it is important what gear you use to run the Novas, though. I use a Pass XP-30 preamb, VPI Prime Signature turntable with an EMT HD006 cartridge. I think these are pretty "true" components, in that they don't color the sound much. My phono preamp and amp, however, are not quite so straight up. I love the ARC sound, and purchased a used PH-7, whose tube infusions I love--a touch of bloom and wide soundstage. My amp is a Hovland Radia. The only non-tube amp that Hovland made. It is so mellow, I love it, and like the ARC 7 is a perfect match with the Nova Vs.
I have heard that the new (Nova) sound of the SF's is more transparent than the older sound. With the right gear in front of them, I think the Novas are spectacular. I heard them demoed with Macintosh gear and the pairing was very smooth. I can see that if a person puts the wrong (analytical rather than musical) gear in front of the Novas they might sound harsh. The way I have them set up, they sing.
