The Khartago was rated very highly by TAS. I personally own a Stratos and it is an amazing amp. The Khartago is a lot of amp for very little $$$. It also comes with a 20 year transferrable warranty and the build quality is incredible for the price. If you were to buy the amp through a dealer, it would probably cost over 3K. It would definitely be my choice. The Cyclops is a Khartago with a preamp built in.
