Thanks for the info M Code, yes it seems Sherwood have a prominent role in the HIFI world without having to use market and distribute their own products. However, I have had a lot explained by Pogre and Rojo about buying a new set of speakers rather than a new amp to improve the sound, but could two different amps with different power ratings affect quality of sound even with the same set of speakers too, especially if one AV didn't have enough power to drive a speaker properly?
