Mine came with aquilas on it. It improved a lot to my ears when I put some Worths on it. I tried both Browns and Clears, I am not sure which I prefer.
I'm not a fan of Aquilas either sound-wise or feel-wise so it's not a suprise to me that the uke sounded better to you with Worth browns and clears. I've only ever tried Worth browns which to me, have a warm and mellow sound. They're good strings if that's what you are going for but what I like even more are Martin and Oasis strings. Both are brighter sounding and to my ears, a bit louder than the Worth browns. Maybe it's just that I hear the brighter sound better which gives the impression of more volume. I don't know, I'm not an expert either.
Thanks for your feedback on the uke. I think you're feeding the itch I'm not sure I should scratch. I already have four ukes which is managable but I thought I was really pushing it when I bought the fourth. Buying a fifth may be pushing it over the line with me. But like I said earlier, this uke checks a lot of boxes for me.
-It's a soprano and I don't have a soprano which is too small for me to play comfortably and effectively. Since this one has a concert scale, playing a soprano comfortably would be possible for me.
-Adding it to the collection would be adding something different, not something similar to what I already have.
-I've always kind of wanted a mahogany uke and I don't have one. This one's solid mahogany. (and I still like the look despite it being quite plain)
-It has a satin finish. My first uke (which I've since sold) had a satin finish and I loved it. (and miss it) All my other ukes have a gloss finish except the ziricote one has a satin neck finish which I love.
-It's very reasonably priced. Even with a case I could probably be all-in for less than $200
