I think that the older Krells like the KSA50 are better sounding then the newest Krells being manufactured now. The older Krell has a very sweet sound with lots of presence and midrange warmth. It delivers the musical goodies. In comparison, the Halcro I think is a little too analytical sounding. It's too clean and sterile. Like wearing a condom every time you listen to music. I would rather get down and dirty with the Krell.
