I like the Ksa-250, it is one of the best amps ever made by Krell. The 250 has much better midrange than the smaller 150, the downside, more heat. Krell still has great service on these amps should you ever need it and can change over to monoblock on the 150/250 models. I have a Ksa-250, IMHO, it is better sounding amp than the 200s and beats out the big 300s also but with less power than the big 300s.
