Need suggestions for bookshelf speakers to pair with an Arcam A70
Happy wife, happy life : ) 
Recommend a power amp to pair with Yamaha A-S1100
At this point - after spending serious $ on speakers and the integrated amp - I’m hoping for a decent yet significantly more budget friendly power amp. New or used. I’m talking $500-$2000 (hard stop). The power amp can be upgraded in a couple... 
Recommend a power amp to pair with Yamaha A-S1100
The power amp would need to be "gain matched" to the gain of the S1100, unless you would be using an active adjustable crossover. That’s true, or you can use the Yamaha as a pre-amp only and look for an power-amp powerful enough to drive your spea... 
Hybrid tube / SS system
The Yamaha units seem rather bland and flat with their "Natural Sound". Or am I crazy? Or, are the Cerwin Vega D-8's an issue? Your CV are great speakers for parties, if you looking for more warmth and refined sound, my suggestion is upgr... 
What is the voltage To bias a marantz 8b?
The one caution I would cite for the OP, if he purchases that device, is that if the tubes are removed shortly after the amp is powered down he should be sure that his fingers do not come into contact with the pins of the tubes while they are ... 
Class D amplifiers have very little phase shift
I'm not worry about the small inductor, but the capacitor parallel to the speaker. 
Class D amplifiers have very little phase shift
I don't know, just based on this https://1.bp.blogspot.com/-Ni37SFEN2MQ/XlP4XBgOSjI/AAAAAAAAMzk/L8hslF5zwbIQoO_EyctCbn5gWvDOwnyBQCLcB... 
Class D amplifiers have very little phase shift
@erik_squires Would you please Xsim with a 1mH inductor in series to your speaker and also with a 10uF capacitor parallel to your speaker and show us the result? 
What is the voltage To bias a marantz 8b?
Adjust both output tube cathode current to 50mA and you will get 0.68V across cathode resistor.

The most critical parts when recapping
There are a bunch of tiny caps, like 10uf 50v. Worth swapping out? If you have the time and skill, replace all Electrolytic Capacitors, they 'age'! Relays on amplifier protection circuits also caused problems went they get old.  
sub-woofer/speaker wiring
RCA Y connector will work.  
MX132
I have a pair of MC2100 amplifiers. I recently purchased a MX132. I am having trouble connecting my amps to the Zone B out put. I can connect them to the fixed out puts but than I cant use the volume control. Can you using the gain knob on MC2...
