Not sure that is the case as the "SV" circuit design is relatively recent and using "SV" in a product name just signifies the product is based on that circuit, afaik. In any event, the 30SV has been out for a number of years without an externally recognized update, such as a mk II, and with all of the new amps and one CD player they have come out with in the meantime, one might suspect an update is in the works. Or, they could be working on the phono section and DAC :)

So the initial word is that the 500SV has some parts not available when the 500AR came out (the AR did feature the Super Veloce topology). Not sure if this results in sonic improvements, but time will tell. Really glad more folks will be able to experience these amps.

Agreed. These amps deserve more profile than they have received, and hopefully this is a regular production model that many folks will get the chance to hear. When I dropped them into my system, it may have been the biggest improvement I have ever heard from any single component. They replaced 400 RS monos, that already sounded pretty darn good.
