I have heard these amps and I feel there is not a better sounding amp for the price of $5K. What a bargain considering the build quality and sonic's. It does take quite some time to break-in. At least 140 hours of listening on and off. If you want to do continuous break-in by leaving it on all the time, you need at least 200 hours. I suggest just listening as you would and it should fully break in after 3 months. Be sure to leave it on if you are not using as well. Awesome AMP!!!
