Anonymous or not, your comment was directed at him and put him in a non-
flattering light. Perhaps his comment was too flippant as stated, but it seems
having experienced both speakers, he does not feel there is much sonic
difference between them - true, a subjective conclusion - at least not as great
as the price difference would suggest.
I do have a bit of a problem with the question as originally framed - OP asks
if the differences are HUGE - well in my opinion the 3A is better, but not
HUGELY so, and even less so when OP already has a subwoofer which goes a
long way to bring the 2s closer to the level of the 3. Are their differences to
be had? Sure. Is the overall quality better? Probably. But both speakers are
clearly the work of the same designer, and if the differences were huge that
would not be so apparent. Doesn't mean it is not worth upgrading to the 3A,
that was my preference too, and still a good value, but not the killer value
offered by the 2s. If OP is anywhere near New Jersey, he should go visit John
at Audio Connection - a good place to hear the differences and get good
advice.
