These products are not represented by the same people. Wavac is by tmh audio who is the US Importer for WAVAC Audio, Köchel, Miyabi, Pure Silver Co.
Viva was originally represented by Victor Goldstein of Fanfare in New York until about January of 2000. He also (previously) brought in Jadis and now represents the German Physics line. If you received rude treatment concerning either Jadis or Viva, It was someone other than Victor Goldstein, as he is a gentleman.
Viva is currently brought in to the USA through Dallas, TX. By an importer/audio dealer. The owner of Viva is Giampietro Schembri of Grisignano, Italy.
As far as performance, the Wavac is one of the best amps of its type ever built. I have heard all these mentioned, except for the German Physics. The Lamm amps are also worth consideration, as they are a very stable product and offer extraordinary performance with excellent reliability.
For the record, I own none of these currently.
