Krell makes amps that are built like tanks. USA made to last at the top of the audiophile food chain. Krell has crazy dynamics. From quit to blowing your roof off with bass and back to quite. This is a true audiophile top notch amp. I will put it up against any anp in its class including the boutique amps. I has my tech clean and service it and its ready for the next 10-15 years. Sound is factory specifications and its ready to go. This baby will drive any speaker you can throw at it where other amps would sound like 15 watts. It works flawlessly. Power cord will be included and if you pay full price i'll include a set of mogami gold balance cables for free. Talk to me !
