old news, over a week ago I saw on Krells web site that they had already recalled the amps, the difference being that unlike most companies Krell not only provides the new fuses and directions for their install but compensates the owner to the tune of $100 for the trouble.
It's what's called stepping up to the plate and correcting the problem.
The amps that have the problem are the KAV (Less expensive line) series.
I use to own a KAV-250a amp, and it hardly sucked. It was very competitive with it's AV oriented competition (Primarily Proceed, ATI and similar products)
As far as "most of krell equipment sucks" that's typical audiophile snobbery. Krell is the best known high end solid state electronics manufacturer and just like B&W (The best known high end speaker manufacturer) Audiophiles love to attack the big guy. Just like any company that's been around for 25+ years they have occasionally produced a piece or two that didn't perform up to their usual standards. Just like B&W Krell's equipment generally offers exceptional performance.
