During the Black Friday melee I was able to land a set of R-26F speakers with a R-10SW sub for quite cheap. I am running them from an old (15-20 yrs.) Onkyo receiver mod. TX-SV414PRO, 60 watts per channel. I'm not sure I'm getting all that I can from my speaker/sub set up using this receiver. I have all my music on Ipod so I had to hook up a Rocket Fish Bluetooth adaptor to the rca connections so it may be possible I'm loosing something there as well. Would it be worth my while to take the money I saved on the speakers/sub and invest in a new receiver. If so, any recommendations?
