Many thanks for your suggestions, you've been very helpful.
Are the speakers going to be able to be away from the walls or not? That will affect your choices
Well, unfortunately I wouldn't be able to place them any farther than 30-40 cm away from the wall. Does that necessarily entail having to go 'sealed box'?
By the way, I probably should have specified that I'm not from the US, and I wouldn't be able to audition or purchase those Tekton M-Lores and some other specifically US-manufactured gear except via ebay or something.
As for the source, I don't have one yet. I have a large FLAC music collection (as well as about 100 CDs), and I'm thinking of using a PC + DAC combo as a source first. If that option doesn't work for me in terms of sound quality, then I'll buy a CD player.
