I already had the Logitech Z-2300 on my PC, I offered the Z-623 at Christmas to connect my TV thanks to the RCA jack! Nothing to say, very good material, good sound quality, at a reasonable price for a 2.1 system, so do not deny it. The little less, and this is only my opinion, it's the look of the satellites ... not very nice with TV! Z-2300 + were much class ...
