Second-hand entry-level speakers to pair up with NAD C 315BEE amp

Hey audiophiles,

I am currently building my first decent audio system but I am trying to stick to second-hand components, as I might need to move overseas a couple of years and I don't want to lose a bunch of money when moving out. I managed to get a NAD C 315BEE amp (according to reviews, a pretty good entry-level amp) and I am bargain hunting for some suitable speakers. They have to be bookshelf speakers to be placed alongside the TV, I am a bit limited in terms of where to put them on. Unfortunately, this is somewhat below ear level.

The source would [mostly] be my computer/phone playing 320 kbps MP3s (Spotify Premium) or FLAC (from ripped CDs) connected through a 3.5 mm to RCA cable. Music genres are quite varied, but main ones are (1) acoustic-ish stuff (e.g., The National), (2) late night beer music (e.g., Radiohead, Sigur Rós) and (3) synthpop/electropop (e.g., Chvrches, Robyn). I will be sitting on my couch, placed about 1.5 m away from the TV. My budget is around 1000 Danish kroner, but I am open to expanding if it is really worth it. But again, for something that I will probably need to give away in a couple of years, I am a bit skeptical of spending too much.

Here in Denmark DALI speakers are super popular and the second-hand market seems to be flooded with Concept 1's. I listened to them and I was not very impressed, though (too bright?). Concept 2's might be better but are not listed as frequently. I am trying to get a hold of a pair of used Zensor 1's (very well reviewed, apparently) but I have been unsuccessful in my bids so far, so now I am considering other options.

So far I set my sights on Mission M70s (500 DKK) and a pair of B&W DM600 S3 (1000 DKK). I am aware that the B&W's are very likely the better set, but for the price, I am seriously considering going for the M70s although I cannot find much information about them online. Any clues?
