Well, let's hope Vladimir Shushirin lives long. I believe, there will be a few places that will service pieces like Lamm and Rowland. If not, they only need service every ten years, and if this becomes impossible in ten years, that's all right. Lamm has a cult following, those amps will be serviceable for a very long time, little doubt. Biggest problem might be special tubes that he uses, matched to each unit.
If you will forgive this, I don't need this vintage Japanese junk, either serviceable or not.
