NuForce
NuForce analog switching amplifiers are in my opinion the best value in compact, high end, ultra low heat amplification. Many users have remarked on how open and natural they sound - a welcome departure from much of their competition. NuForce is an exceptionally innovative company and has come out with quite an array of products. As of this writing I don’t have a pair of their loudspeakers on hand, but I think the basic approach is very promising.
