Wally, I have a 125 Anyos. It is basically an R4 with different tie block and rosette. I had it set up with D'Addario EJ45's. I have tried Savarez 520R, Savarez AJ500, Augustine Classic Red, henSe 500MT, Ramirez Med Tension with carbon G, LaBella 2001, and LaBella 2001 Flamenco strings.
The D'Addario EJ45's were the last set I had tried. Every one of the aforementioned strings has sounded great on that guitar. So far the set that sticks out as having dark sounding basses was the Savarez Corum/Alliance AJ 500. I also have three sets each of Dogal Diamanté trebles and Savarez Cantiga basses on order, following petermc61's advise. That guy has forgotten more about CG strings than I will ever know.
I tried all those different sets and nothing really blew me away as being superior, except for maybe the Ramirez. The trebles sounded warm and clear and the basses were deep. I just keep looking because I am trying to find an affordable set, but haven't been able to find trebles and basses that I am crazy about in a ready made set. I like the Ramirez strings, but they are quite expensive. I had the guitar set up with the D'Addarios because they are like $6.00 a set and are quite a neutral string. If it sounds good with D'Addarios, chances are it will sound good with just about anything. I will let you know how the Cantigas work out for me.
