Burned in ultimate cables do not sound thin to me. If I were you, I would have inquired about purchasing one or two ultimate cables, and after two weeks, go back for more. Personally, I don't feel like I'm missing anything with the Ultimate cables. Not thick or thin, not bright or rolled off (after burn in of course), I would say that it's in the Goldilocks zone. I bought a well burned in ultimate cable from a member here, and it sounded warm compared to some of my other power cables. If they aren't for you, you won't have a hard time reselling ultimate cables in my opinion. Just remember to give them a week or two of use, before any final judgement. If you're like me, you will not like it at all for the first few days, but it will get better. The ultimate cable has the biggest change with burn in than any other cable I've tried.
