My amps were also delivered today and it took couple of minutes to set it up. They replaced my 100lb monster Pass amps. Powering from cold, my initial impression after playing couple of songs is that these amps are a killer. I have the SI installed and also got the Sparkos along with it. Not sure if I will ever use the Sparkos since the SI sounds very good with the Cary pre. The amp runs cool which was one of the important factor (and my listening room doesn't have air cond) - so no more sweating. There is nothing that I know would compare these at its price point. I will post later about the sound quality after some initial breakin but so far I am a happy camper. Bravo Collin - an incredible job done.
What do you expect after 300hr break in ?
