@iwanami  - Either of the speakers you mentioned will work. It's simply a matter of trying each and deciding which sounds better to you. 

Thanks for the replies everyone. 

Thanks for the reply.

I am now thinking I will just go and grab some new bookshelf speakers.

Something a little better than the ones I have. So hard to know what they will sound like though.

Try the speakers you already have available to you. They may meet your needs. If not, buy some new speakers. That way you have a reference to know if the new speakers were actually an upgrade over what you already had.

If you do decide to buy new speakers, check out the reviews by Zero Fidelity and Steve Guttenburg on YouTube. Both of them review several budget priced bookshelf speakers.

I'll offer one opinion, if you don't mind..... Buy speakers that are sealed enclosures, or have ports on the front (not the back), if you are limited in space and require the speaker to sit close to the wall behind them.
