I am torn in two at the moment (not literally). I am wanting to upgrade my Amp/Reciever, I have a Sherwood 6090RDS bought approx 2 years ago. The Amp is fine but i want to be future proofed for DTS and also i'm not happy with the Sherwoods bass. I have short listed 3 Amps, the Yahama 596, Pioneer 709, Yamaha DSPA5. All seem to get good reviews but what does the general public think. My current Set up is a Panasonic DVDA100 (not DTS compatible) Mission 77C1 centre Mission 702e fronts Mission 701 rears Yamaha SW60 Sub With the above, would i hear a difference ? Is it worth the extra money buying a different Amp/Reciever? Thanking you in anticipation.
