One more time, then-- Hey! It's Christmas!
-None of the amplifiers listed follow your rule- TRUE! They have their own priorities and reasons-- mine work better.
-What source component outputs 7 volts?- The LYNX L-22 computer sound card puts out 3.5/3.5 or 7 volts balanced. Most Blu-Ray players output in this range also. This is absolutely ideal for a passive volume control/attenuator. Blu_Ray movies are now the best sound the consumer can easily buy.
-I can only guess that you have your passive VC preamp turned way down-- It normally runs at 1 to 1:30 O'clock.
-none of this has anything to do with dynamics- Oh, but it does, and the difference is large. You're dealing primarily with the S/N (signal-to-noise-ratio) of the interconnects used in the system.. Any wire has a "perfect" power range where it performs best. Put too much energy into it, and it balks, put too little in and it becomes a poor conductor at that signal level.
This does depend on what interconnects are used, how good RCA jacks are, etc., but in general, the boutique wire makers have this pretty well ball-parked for their intended uses.
If you build your own cables & interconnects, (I sometimes do, and sometimes I buy them-- depends), then you'll want to take a look into that.

The LYNX L-22 computer sound card balanced output is pro +4.
That's a different conversation.
BTW I didn't know your passive VC was balanced in and out?
I know, as a fact, that your power amp does not have a balanced input. So why would you be using the balanced output of your sound card?
The blu-ray players I looked up have 2 volts outputs but there is no standard, no rule.
"We've found some BD players output at 2Vrms when presented a 0dBFS signal while other outputs are at 1Vrms."
You said,
"You're dealing primarily with the S/N (signal-to-noise-ratio) of the interconnects used in the system.. Any wire has a "perfect" power range where it performs best. Put too much energy into it, and it balks, put too little in and it becomes a poor conductor at that signal level."
S/N (signal-to-noise-ratio) of the interconnects used in the system? Really Dennis?
Too much and the wire heats up and the DCR goes up and it becomes a poor conductor.
I guess you can call that "balks" if you want to but 2 volts or 7 volts or 20 volts into the input impedance of the power amp is not enough current to heat up the wire. So once again you are wrong Dennis.
As for "too little in and it becomes a poor conductor", that is just so ridicules I won't even offer a retort.
These things are all just more of your made up stuff Dennis with no basis in reality.
You can have an opinion but when you state your opinion as fact, without showing technical proof, then you and I will have a problem.

You remind me of a "computer tech" years ago who told me I can't make RS232 cables with 22awg wire because "the thicker wire soaks up too much data".
P.S. To the more technical here: Lets not get caught up with all the RF theory that would support the computer tech's theory with high speed data transmission! This was 9600 baud at less than 50 feet! As with audio signals, data signals at that rate and equivalent frequency are not sensitive to these parameters.
And FWEIW, CAT6 cable is 23ga where as CAT5 is 24ga due to the RF issues.
