Upgrade from Paradigm Studio 100 v2 speakers [real cases only]

I have had them for almost 20 years now, they did not disappoint.
These v2 have great bass too, unlike v3 or v4 as I heard.
Anybody upgraded these speakers? Any opinions for before and after?
I was thinking about Tekton's Double Impacts for a possible upgrade.
Let's disregard for now the "it depends on your other equipments".
Any cases?
Thank you.

I owned the Studio 100 V2 for about 3 years in the early 2000s. They were nice speakers for their price point and time period. Many other speakers have come and gone in that time. I have owned the Double Impacts with the $300 upgrade for a little over a month. The DIs significantly out perform the Studio 100s in every sonic parameter for my tastes. Not even close.
I have had the Paradigm Signature S4s twice and ran with a JL sub since then. I liked them enough to buy them twice. I enjoyed the Sigs much more than the Studios. Again for my tastes the DIs do everything better. YMMV
Standard they are not bi-wired although for a small fee I believe this is an option. Any specific questions you can call the number off the Tekton web site. Eric usually answers and can answer any questions you may have.

System matching is the single most important factor when building a system. Its not something you can save for later.
