Speaker up grade options. Current system, Yamaha RX-A 3010 Advantage Amp. 5 x Paradigm Millenia One speakers 1 x XTZ 1x12 Sub I want to expand the music side of the system and am feeling that I want to go the 2 channel speaker route rather than using small drivers in the MilleniaOne’s in combo with the sub. The crossover point @ 120Hz is impacting on the vocals and the bass is slightly disjointed. So I am thinking of moving replacing the Front left and right channels with a full range speaker. I like rock and new age music along with some classical. I think I need solid base and clear vocals. Size is an issue lol. Floor standing speakers are not going to work with my room, and the speakers need to be close to the wall I have a budget in mind of up to £2000 and am think of replacing the amp to an Arcam 550. With an option to go DTS-X. I think the Sound correction could be good for my 5m wide by 4m room. So what speaker wise would fit the bill?
