I have both systems and I use the 5300 with my PSR 3000 and my 5500 with my Tyros and both are fantastic systems that leave you wanting for nothing....BTW, when it comes to the Logitech speaker systems, trust in what Gary (Travelin'easy) has to say...he is the expert in this field and is responsable for most of us using them..Thnx.
