260 has a higher rating than the 240 ... slight better performance .. for 50 bucks more .. might as well
dont mismatch the company of ur speakers ..
tho the altecs are awesome ... u could consider them if u want
if u can hear a demo before u buy that would be the best ...
( im not sure the altecs less than 5.1's perform better than creative tho ... it rules the higher segment thats for sure ...viz 4.1 and 5.1 )
