I listened ARC setup (with ref6 pre, ref9 CD and a power amp, guess it was 150, I guess) just once, I liked it but I'm more familiar with Accuphase.

...And I thought that class Ab deliver bigger soundstage and more power, better suited to larger rooms...

Im not sure I agree that you need more power then the A70 in a 500- 700 sq feet room, my room is 643 sq feet and my A65 drivers my 4ohm 88db speakers to 90-95 db crystal clear and compresses the room just fine. Depending in the sensitivity of your speakers I think there are other factors beyond the A70 not being able to drive your speakers to your desired listening level.The A70 also has a 800 damping factor which is twice the amount my A65 has.
The P7300 I have no experience with. |

Is your room acoustically treated or do you use any electronic compensation? |

Usually I don't listen music very loud but sometimes I have visitors enjoy super loud music. If I turn volume too loud the music of strings and brass start to sound harsh. Maybe this "deterioration of sound quality" is not just from AB amp. I probably excessive expect my lovely P7100. |

Interesting that the most powerful Accuphase @8ohm is the 180wpc E-470 integrated amp.

@ktliao88,
I cannot make to belive me 100%,normal,but try without DG-58,take care of line and of ground of all power cable,and!! don't use anymore on Accuphase gear Siltech and Cardas cable! If the problem persist,try with another final amplifier ,maybe with 2 M-6200.(this make wery good pair with c-3800 and B&W 803,(this speaker are at least a level below amplifier and source!!!). |

A very good step forward!
Do not forget to consider the phase of powering all the devices in the system. If it is possible to find out what is the real phase at the iec connector at the input of each device (not all devices comply with phase and zero standard), you may have a great improvement on sound. |

I'd be cautious about the bridged mode suggestion. Success will depend on the difficulty of the speaker load. I owned a pair of A50 amps and found that they worked fine when bridged but didn't sound as good as the unbridged configuration when driving my Martin Logan stats. If you want more power, consider the A200 or A250 since it will provide more power by strapping (parallel connecting the channels vs series connecting in the case of bridging) the outputs together. I don't believe an AB amp, all things equal, will ever better the A amp in regards to sound quality.
