Now I sorted the picture output from RAD 8500DV card to my conventional 29" Sony TV, I now need to improve the sound quality. At present I have RCA cables connected from the RAD 8500DV breakout box to the RCA ports on the Sony. I am looking at purchasing a good amplifier and some good speakers. At the same time I will upgrade my RCA cables to some good quality OFC's. My question is? Is it possible to connect using twin OFC RCA cables from the RAD 8500DV breakout box direct to the Amp and then connect the speakers to the AMP? Please can you help and also let me know which amp models to go for also OFC and speakers. Thanks in advance.
