The ebb and flow of the hifi market happened. It seems that more folks are using tubes these days. The tube integrated amp has increased vastly in the last 10 years or so especially. The days of the expensive SS amps, at least those built in the USA seem to have ended. Krell, Mark Levinson, Jeff Rowland, Threshold....those were the 80's and 90's. There are still expensive SS amps from darTZeel, FM Acoustics, Goldmund, etc., but they are made overseas.
What happened to Krell
I was out of the HiFi world for the past 8 years and in the past few months that I have been back, I never hear much about Krell anymore. Are their products not as good as they used to be? From what little I have read, it seems like its their low priced (low for Krell) equipment isn't what it used to be. I have not read any reviews, but I am so surprised because they were the one main alternative to McIntosh that I was looking at when i was considering Dynaudio and B&W speakers.
