Everyone's given me great advice and thank you for that
Two conclusions from what has been said that seem to be the most useful and deserve a follow up question.
#1. Budget is the core question: Or main factor when making a purchasing decision for the home theater.
#2. Subjectivity plays a role too: But (question here), budget aside, is there a way to qualitatively say that speaker "A" is better than speaker "B" by XX%? This is regardless of one's budget. I ask this because a cheap speaker likely won't sound as good as the most expensive one - but is there a way to measure that side by side (watts, ohms, etc...)? If so, then couldn't I do a side-by-side comparassion of what I currently have with whatever I am looking to buy and then decide if the purchase is a good value aside from my budget?
If there is such a way, maybe there's a web site or something that can help. Maybe that was my original question (to remove the subjectivity out of the equation). In a math problem it may look like this:
(A) Bose Accoustimass 6 + Mitsubishi M-SUB 10 (subwoofer)
(B) Onkyo SKS-HT540
(C) X Brand & Model
Attribute 1 (watts for example): (A) = X (B) = X (C) =X
Attribute 2: (A) = X (B) = X (C) =X
Attribute 3: (A) = X (B) = X (C) =X
Attribute 4: (A) = X (B) = X (C) =X
Or maybe this is a niave way of trying to think about this.
Again, I love the feedback - it is helpful. What a great thing to be able to turn to a community and find answers that you couldn't get in the "real world".
Sincerely,
Paul
