No, I haven't listened to the speakers mentioned.
I took the OP to mean that the newer one was an updated design compared to a previous model that had been around a few years. Typically, when speaker companies bring out new models, they usually at least claim some technological improvements. Whether it be new cone materials, driver design, cabinet type etc.
With regard to the OP, if I already have a great performing speaker that I like, something else better really grab my attention when I hear it if I intend to replace what I have already, regardless of where I get to audition it. Fortunately for me, I can tell a speaker that will work for "me" by listening to it near field, and individually. Second would be the published frequency response, and how the speaker works full range.
My question to the OP would be, what is it that you feel is missing from your old speakers? Do they distort more now, lack of bass, or any other part of the frequency spectrum? I don't easily take a manufacturers claim with regard to upgrades. I tend to hold them to their original boastful claims the last time they sold me on something new unless it actually sucks. Why? Because if the upgrades are audibly subtle (which most are), then the newer model's improvements will be lost on me 20 minutes in as I get used to them and the only real difference will be that my pockets are emptier than before.
IMO, there are just too many speakers to choose from these days that offer pretty much the same audible performance in a different package. As someone who has been used to large displacement speakers for the last 40+ years, I would find anything with less than an 8" woofer underwhelming, regardless of quality. Bookshelf designs to me are an immediate downgrade that need a lot more help after the fact, such as subwoofers.
When I get bored with audio, I don't try to improve so much via some relatively empty upgrades, but just put together different types of systems, or high performing portable types that knock my socks off in different ways. But, if I am honest with myself, my main system is the one that really can't be beat with regard to what I can actually hear anymore.
