Sale about to happen, what do I buy?

[Oscar]

Hi guys,

A retailer in my home country of New Zealand is about to have a crazy 12 hour sale tomorrow and I am unsure what speakers I should buy. My two options currently stand at;

Logitech z600 for $64 NZD or $51 USD (http://www.pbtech.co.nz/index.php?z=p&p=SPKLOG2445891&qr=ec_12hr-OctoberA_56)

Logitech z506 for $87 NZD or $69 USD (http://www.pbtech.co.nz/index.php?z=p&p=SPKLOG1196579&name=LOGITECH-Z506-Surround-Sound-Speakers-5.1-channel-)

 

Are the cheaper z600 an alright desktop speaker for standard youtube/movie/casual games? I like the ability to stream wirelessly from my phone/shield/computer and also like the look but I would also like the sub and speaker set up from the z506... I will use headphones for any serious gaming or immersive experiences and my current speaker set up comes from a budget HDTV so anything really is an upgrade.

 

What do I get??

 

Thanks for the help in advance
