Sorry, I missed this earlier. Yes, early last year I found out about the chokes because I "ventured" into a 3.6s discussion.

Upon reading about the sound improvements that the chokes caused in the upper Maggies, I had a haunch.

I was already getting something akin to these improvements, but in my MMGs. Not "ribbon" sound, mind you. But at least far better than I had before the "capless" tweeter mod that gave me these improvements. Given some drawbacks of going "capless", I wanted to move on to a line-level xover.

One little problem with that...early tests suggested that in simply going to line-level, I could lose a valued contribution of "capless".

This contribution was better imaging and 3D soundstaging. When I read that the chokes were doing this for some of the upper Maggies, I JUST HAD TO TRY!

I got the chokes and I also went to the line-level xover. It worked, grandly.

Around that time, other users picked up on the discussion of the chokes and tried it in their non-ribbon Maggies. Many reported solid results. Others could not hear much of a difference. All I can say is that, here, they have become key to enhancing the 3D imaging sound of my system.

Al Sekela is the originator of the chokes idea. If you search around for his inputs, you will find valuable details.

[Edit: I forgot to add that imaging attributes are not the only contribution of the chokes to my system. I consider them partly responsible for the cleaner-sounding upper registers in my tweeters. I had never expected the upper end to get this good because, indeed, that is "ribbon" territory. On SACDs, friends can't believe the extension and cleanliness that these cheap old MMGs can deliver. That does not happen if the chokes are off. It will only get better the day I can afford 3.6s]
