There may be some tube amp companies that have reliability problems, but I don't think ARC is one of them. I've owned at least half a dozen ARC tube amps/preamps since 1978, including a VS55 and VSi60 currently, and I wouldn't keep buying their products if I had been experiencing problems with them. Yes, tubes have to be replaced, you have to make sure the bias is set correctly, and occasionally you may have to replace a resistor if you own the amp long enough, but this company did not gain its reputation by making unreliable products.
Audio Research VSi60 integrated reliability?
Just wondering the reliability of the VSi60 integrated. Am tempted by the idea of a tube integrated, but a little wary with the stereophile review and comment about exploding units. Saw a previous a'gon posting with quite a few replies about another similar situation which seems to have been deleted. Anyways I hear quite a lot of positive remarks about ARC's reputation and reliability, but those posts frankly are ridiculous if the amp is exploding.
