I have no complaints on the sound quality from the Speakercraft amps however I have had to replace them four times in a year. The first three they covered but the inconvenience and time has made me furious. Now they seem to not want to replace a unit. That lasted a month I am now replacing a BB2125 with a 9 year old Denon POA 2800 that has never missed a beat from my old house. We have a house filled with their products and have had a ridiculous series of problems from the very start. I will not ever buy speakercraft products again. Thanks PG
