Does impedance of a speaker change when one bi-amps?
IMO, parametric equalizer pair with active crossover can make a huge improvement! 
Setting up 2 power amplifiers to setup at once help?
Might consider using the 2801 to power the highs for your speakers and the 'sub' out from the 2801 into the Yamaha to power the lows. Imo, it's not a good idea, you don't want to use a active crossover in the receiver and the passive crossover...

If they add a tape loop after the source selector will be very nice!

Just got a Schitt Loki mini for mine! How you connect the Schitt to your Kinki ? 
Any meaningful differences...
I like stepped attenuator because I can matching resistors for perfect channel balance and alter logarithmic curve to my liking.

How nice if those still available in record shops and drugstores! https://www.ourfavoritegadgets.com/images/vintage-tv-tube-tester.jpg

I helped my friend wiring 8 speakers for his 2000sq ft. restaurant dinning room powered by a 80Wx2 receiver with satisfactory volume level.

Try connect 4 speakers as a group follow the wiring diagram, one group for right channel and one for left channel, leave the last speaker unconnected and see what’s the result.http://www.colomar.com/Shavano/4ps-spkr.gifhttps://www.amplifiedparts.c... 
If I buy electronics from England, will I need some sort of converter to use them here?
Its wall wart is multi-region, and come with plug adapter.  
Powering nine home speakers
Can I ask what’s the risk if the impedance doesn’t match (ie using the current speaker selector and a second amp)? Harm to the equipment or just uneven sound? Not too many power amp can handle 2 ohms or less load, Some amp protection circuitry wil... 
Can this be good first tube amplifier?

Discontinued equipment that you wish were still here. What do you miss or think will miss?

it references:impedance protection circuitryandImpedance-Matching Autoformers safely distribute maximum power throughout your system. The TSM8 and TSM12 come with autoformer and impedance protection circuitry, not on the ATM7! 
Powering nine home speakers
I suggest you try this first: Onkyo front left and right speaker outs --->  speaker selector with impedance matching ----> speakers Imo, when you parallel all speakers without impedance matching, it give a very low impedance for the On...

The OSD Audio ATM7 7-zone speaker selector dose not provide impedance matching, try one speaker distribution selector with impedance matching, if still has insufficient music volume then add a higher power stereo amp connect to the Onkyo front R/L...
