Good External power amp in small room, will not overkill . But you need to careful the power rating of your power amp only. Don't select the power amp too powerful. until sound level setting minimum value -12db still cannot get the 75db standard.

Denon use Audyssey auto eq software to measure & calculate three thing, Room EQ, distance ( delay time) from speaker to your listening location. Sound level 75db from each channel & subwoofer to your ear level position. The purpose is make sure every channel come to your ear is same loudness & same speed. If one of your channel is too quiet or too loud , too slow or too fast. You surround sound quality will be drop. So Audyssey try to adjust sound level of each channel until 75db standard, even you are using different power amp to drive your speaker. So when you are using over powerful amp & your listening position is very near from your speaker. Audyssey may detect you need -15db to get 75db, but Audyssey limit to do -12db adjustment only. This is situation, you need to avoid. Sound level 75db is very important, over 75db your sound become Rough， less than 75db become weak. Because so important, denon &　marantz ecourange people use professional sound pressure meter to measure the buit in test tone generator , avoid you get wrong sound level other than 75db standard.

Calibrating levels using a Sound Level or SPL meter

Marantz 7055 will not overpower. But not much improvement from your denon 6700 internal power. My friend who use whole set svs ultra system, he suggest you use the denon internal power first. After a while , find another power amp better than marantz 7055.

Yes 。 Emotiva XPA-3 will better than Marantz 7705. My Friend which use same svs ultra center as you , now using 200watt power amp to drive .

Sorry, My friend give wrong information, He is using Arcam p777 only 7x150 watt. But his room is smaller than you, 2.895m x 2.926m. Emotiva & SVS dealer in Malaysia should be Maxx Audio Visual Trading Sdn Bhd. I saw his website show Emotiva product. https://www.maxxht.com/

Normally reference is better. This is default calibrated setting with a slight roll off at high frequencies, which is optimized for movies.

His room is full of heavy room acoustic, No more standing wave.
You should try to contact maxx audio boss ask for further info. He is friendly & good service.

Actually best connection is separate output. Video hdmi output send Pure video signal without audio to TV , another Audio Hdmi ouput send pure audio signal without video to AVR.
This way you get better video quality & better audio quality compare to single hdmi output.

I got one question to ask sifu here, especially Minidsp user. Is it audyssey LPF for LFE 120hz so important? My friends blame their av processor don't have this LPF for LFE 120hz setting. This reason make their audio system bass performance become weak, even they are using expensive multi 15" subwoofer. So they try to use the minidsp set up each subwoofer crossover become 120hz to 15hz with 24db/slope. AVR speaker crossover set 80hz. Now they are happy, bass become strong. But I think this method look like they are not bypass their subwoofer internal crossover, even their already bypass with turn the crossover knob to max value.
Is it this method correct way, nothing negative effect? AVR crossover 80hz 12db/slope, minidsp subwoofer output crossover 15 to 120hz 24db/slope.

After, I also find out many brand av processor like pioneer, yamaha , Sony, NAD, lyngdorf & trinnov. They also don't have this LPF for LFE 120hz setting. This setting only appear at marantz or denon which got audyssey tuning technology.
