Up until 2012 I used only one selling ID (the one I use to post here), this was at a time when free listing promotions were just starting. I was tired of not getting any listing promos while other people seemed to get them all the time. Tjios lead me to start a few alternate selling id's which as I hoped were getting all the free listing promos.
It took me the minimum time to move from "new seller status" to get past the payment holds and selling limits and by that time (90 days) the new id was outselling the old shooting star ID. Over time I moved all my good listings to the newer id's and to this day only use the original one for dead items (and the results prove just how dead they are).
For every buyer who won't buy from a new / low feedback seller there is a buyer who won't buy from a "big" seller with too much feedback.
While eBay MIGHT give a little Best Match bump to an established seller it's probably way down near the bottom of the (100's?) factor that go into Best Match ranking.
Forgot to add.....
On your old main id you have almost 2000 listings, on the new one 61, if there is any reason why you are not getting much action on the new id is because you only have 3% of the number of listings.
Also don't know how you decided what to list on the new id, maybe the new id has the items of lesser interest. Plus you've only been operating the new id for a few weeks so about half those listrings have only been up for half that time or less.
The sale I made today was to a Canadian and it was the Doors CD. I sent him an email stating I saw The Doors when they came to Vancouver on July 13, 1968 and sent him a photo of my tickets. He was impressed and stated he wasn't born until 1974.
