I have an elderly yamaha DSP595A and want to upgrade it for one with HD Mi connectivity. I need a pre amp output for my front speakers to go through my Musical fidelity A308 Amp with Castle floorstanding speakers. The rest of system is a Panasonic Freesat HD TV, Foxsat-HDR with HDMi and a upscaling Panasonic DVD with digital Coax. I have a pair of Sequence 1's for rears and MJ acoustics Sub. My budget is about £400-£500 . Can you recomend a decent upgrade please. Its just for playing AV as I use my MF for music.
