It is the newest amp from VTL, my local dealer was discussing this with me late last year. VTL website is not up to date. Very nice cosmetic upgrade, I don't think there is a sonic difference but I have not heard the new amp.
New VTL Stereo Amp?
I see there's a dealer advertising a "New", "Used", VTL ST-150S - presumably the replacment for the ST-150. It looks great but VTL doesn't have it on their web site yet and I can't find any other info on it. Has anyone heard of it or seen it at a dealer?
