Help with my Canton speakers dilemma

[Thias]

Hello, everyone! I am in the process of choosing bookshelf speakers for my room, for both my vinyl and mp3 collection. Amp that i use is Yamaha A520, which i will eventually upgrade to A1020, although Onkyo Integra 8670 also caught my eyes. As for the speakers, i plan to sell my Allison LC110R for something more modern. After losts of googling, reviews, and reading ads for selling used hifi, my current dillemma is between Elac Debut 2.0 B5.2 and Canton Chrono 502, which both sells for 200 euro. There is another option, Canton Ergo 21 DC, for only 100 euro, which saves nice money, but if those speakers i mentioned before are better, i will rather buy them regardless of the price. So, i am asking for advice, can you give advantage to anyone? What will you choose? Thanks!
