OK,... it's been a couple days since receiving the new versions. With both the new and old version in hand, I can definitely say there is a difference in how they sound. I'm able to tell the two apart by looking at the back of the units, the old version has @ sign, but instead of the 'a' in there, there's an 'm'.
On both sets, the bass (which is most inportant to me) is incredible, but the new versions seems to do a better job of balancing the bass with everything else. Also,... the new version seems to do a better job with the mids as well. I don't have to EQ down the middle so much to get a good clean balance. Fact is, I don't have to tweak so much with the newer version as I did with the old.
I will definitely replace my old version with the new! Twleve bucks sounds like S&H. Sweet customer service! Like I said before, I wished Maximo made Kitchen Appliances like refrigerators,... hell, I wished they made cars!
Thanks again Andrew H.
