Hiya, I currently have a pair of MA B2's running off a NAD T743 AV amp and a NAD C541i CD player I have the opportunity to purchase a pair of Epos ES12's. I realise the Epos is a little old, and the MA's are much more modern, but are also a cheaper set. Would the Epos be a better speaker than my MA's, and would it be worth the upgrade? Cheers
