Excuse me - I am not into electronics. I just want to try out current driven or current feedback topologies here discussed.
I think these are two quite different concepts. One is a low (?) ohmic feedback path - the other is about output impedance. They are definitely not the same thing and don't do the same thing.

Why? 1875... Built as per the Data sheet! is a decent amp.
Not world beating certainly, but better than most commercial efforts of comparable power output .
And especially Why ? if 'Not into electronics' 😉
Could try for a composite build much like the ones developed for the Lm 3886 .
That has proven to give advantage.

You can look at this one:Can you recommend a composite build thread/instruction?

Years ago I put a lot of efforts to build Howland current pump amp using LM1875. Finally I got stable and nicely sounding circuit but far, far away from the sound of the composite amp describe in the thread above. If you have not very good speakers (woofers) a current drive can help but apart from that I couldn't find anything comparable to the sound of the composite.
LM3875 and LM3886 are hard to find, eventhough they are better than LM1875.Why? 1875... Built as per the Data sheet! is a decent amp.

But LM1875 there are plenty of to buy.
Composite topology is much better. The sound is super clean and no listening fatigue.Could try for a composite build much like the ones developed for the Lm 3886 .
