Well, I research the heck out of most things before I buy them. So most important for me is to know what items are available in the sub class of the category I am looking for. Second is budget. Note here, Your stereo speaker listing was so long that it became a meaningless list of numbers. I suggest that when that happens, you break those lists down by adding a further category sub class. My suggestion? Price. Budget is where it's at unfortunately.
What happened for me was this: I'm looking for a new pair of speaker stands and power cables. I perused the buyers guide, found a list of items that suited my budget and looked the items up on the internet. I then contacted the local distributors of the products who have given me some more product details and some dealer information allowing me to make an informed decision on the purchase of said items.So now i'm looking at buying some stuff that last week I didn't even know existed, despite endless googling.
Well done you guys.
