Karan's amps have the bottom end control of solid state, along with a sweet mid-range. They would probably keep the same company as Lamm, Dartzeel, Pass XA series. However, their power is in a league of their own. They may not have the speed and slam in the lower end as Krell or Boulder, but that is OK.
I have spoken to quite a few people recently about solid state amplifiers, and many people find the typical contendors to be too analytical. I never heard anyone speak of Karan as overly analytical.
In addition to the unlimited power and a midrange that is musical and dynamic, I like the added bonus that they do not run hot. That way, they stay on all the time, and always sound their best. My experience with Pass is that it took quite a few hours of being on to sweeten, preferrably more than 24 hours. Very difficult during the summer.
