i just bought i pair of entry level boston cs 26 speakers and was surprisingly happy with the sound. i am looking to replace all my polk audios with boston but want to get something more substaintial then the cs 26 but want to stay bookshelf instead of going floorstanding for the sake of space and plus i have a decent sub so i need need floors. i was looking at the next level of speakers from boston ( the a series) online. but i can't find anywhere local that i can listen to them before i buy them. the spec on the a series don't different much from the cs. it gas a different woofer material and as a little bit deeper bass respense. will i be paying mush more for the a series for not much better sound but for better looks???? its that what the real difference is? does anyone know has anyone heard them both? comparably the cs26 and cs c225 center vs the a26 and a 225 center. if i get the a series i would move my cs to the rear channels.
