The problem with small companies that's kind of run like a one-man show is that you do not have support reliability.
Just check out their bad publicity on head-fi forum
A complainI rather spend more money with established companies, who cares foreign, contacting them is just an email away with the advent of internet.
As far as Audiovalve goes, they have existed for a long period and the Eklipse is a very mature design which was reviewed by Art Shapiro in the very 1st issue of Positive Feedback way back in 2002
http://www.positive-feedback.com/Issue1/eklipse.htmNot only that, Audiovalve claims that the Eklipse is supposed to be the culmination of 15 years of preamp design
http://www.audiovalve.de/eklipse/eklipsee.htmlSo I guess in 2008, the current Audiovalve Eklipse is a 20-year old mature design ;-)
And as far as german products go, this is supposed to be a steal. Check the price way back in 2002 and now, just attribute the price increase partly to US$ decline and you will know the quality/price factor is very high.
