I currently own a sony STR-DB930 AMP and Sony DVP-NS900V and am thinking of upgrading to the Arcam DV78 and AVR250. This has big cost implications and was wondering if it's worth the jump. I have a Pana TX32PD30 tv with component inputs and Bose AM15 MKII speaker system. I have heard bad reports about both of these but I'm very happy with them. Are the DV78 and AVR250 the right choices or should I maybe have the DV79 and AVR300. Will they be that much better. Any advice is appreciated. Ash.
