Sounds like Vac Products require lots of maintenance. What do they do to it and why is it necessary? Super inconvenient for a quality product
You come off as a troll, but just to clarify for the benefit of others:
No, they don’t need more service than other brands. My Ren 3 went in for cosmetic touch-ups needed due to a slightly careless prior owner. And when a component lasts for 15+ years, then it’s prudent to refresh any electrolytic capacitors, regardless of brand. I would wager VAC products have a much longer "usage" lifespan than average, because they still sound great 20 years later.
I have not personally had a failure with any VAC component - 15 years, 9 (I think) components.
