Navision Audio

Maybe they don't understand English at the factory. Does Navision have an American importer? You may want to try them, or whatever importer works in your region.

i took the liberty to visit their web site. they have a north american distributor, rives audio.

several years ago, after their first visit to the us, i reviewed an early preamp and spoke to the designer. at that time, they had a plant in california.

if you read my review, at audiophilia.com, it may provide some useful information.

since i reviewed the preamp a while ago, you may have to search for it, either under preamps, or under my name, roy harris.

I contacted Rives Audio and they wrote that they don't carry Navision Audio any longer.
