I haven't heard the Delos, but, I am pretty confident you will like what you purchased. I've owned a Lyra Lydian and a Helikon, and I currently have a Titan. All were/are great cartridges, all are very long lasting (the Helikon is in a friend's system and it has been going strong for close to 2,500 hours of use), and built to close tolerances (cantilever/stylus straight and true, very close channel balance).
My other cartridge is the Transfiguration Orpheus L. This too is a terrific cartridge. This is the first Transfiguration cartridge that I've owned; so far, it has been terrific. I have heard the lower cost Phoenix and really liked its performance -- very lively, with the kind of midrange presence and clarity that particularly suited jazz recordings. That might be a candidate for the next step up.
