Hello all! I'm looking for input and ideas I'm basically looking at replacing my two front A638's with something smaller (due to new requirements from my dear wife), but I'm not prepared to step down in sound quality (some of you would probably argue that it would be difficult to step DOWN form the 638's ). I also have an aversion (irrational?) to the sub-mini silverdollar sized "woofers" you find in some of the really small enclosures. I will not be wanting to replace the center (NS-AC143) or the sub (YST-SW160). Budget is also a consideration (unfortunately ) Any and all input would be deeply appreciated!
