Krell Reliability?

I have Krell 300i for 5 years driving ML SL3 and nothing required Krell to fix. I will say their build quality is above norm. As for you problems, your local dealer should take care of the problem themshelves, unless you purchased the Krell through internet. In general, purchase expensive item as Krell via internet or mail order would be fine until problem like this happens. It adds the stress factor by 10 folds which something we need to consider.
