well I tried a music hall mambo class A integrated this weekend and fell in love with it,its a sweet sounding 50wpc integrated and mated well with the corns,better bass control than the tube amps I have tried with them and none of the harshness that I have heard with other ss amps. it runs hot but that expected with class A, it also has a 24/96 dac built in though I havent tried that yet but this amp aint goin nowhere,its a keeper! try one if you have the chance
