Using battery power to go off the City's power grid
Most electronic equipment is 100% happy from 108-132 because they are designed to. Mass consumer gear will not even blink.  Only poorly designed, poorly tested audiophile gear has issues. And no, there is no research here, just some listening test... 
What I really hate about some music

DSP vs. active analog crossover vs. passive analog crossover. What is your take?
I don't think anyone will ever quote Nelson Pass in a DSP class, but then again probably not an amplifier class either  
Tube PHONO preamp interference - RFI, EMI, bad grounding?
@filipm    I go back to my original statement. Flawed design or broken. It should not due this. If this happens on both channels, then it is a flawed design. A small capacitor between the signal input and signal ground (or case ground) and the n... 
Wendell Diller: "You don't wanna put a subwoofer with a Magneplanar; it doesn't work."
Not really. The frequency response and phase of the woofer and midrange have to match through the crossover range. That’s the direct benefit of a woofer with extended high frequency response.   No really. After 120Hz you have direct directiona... 
Damping Factor vs speaker sensitivity
@audiosens    Yes technically an amp can have a damping factor that is very high as it is measured at the amp terminals.  I was listing all the parasitic values in a system between the amp and speaker driver that makes this value meaningless.  
Damping Factor vs speaker sensitivity
There is inductor resistance, voice coil resistance, resistors, capacitor impedance, inductor impedance. Your real damping factor is never anywhere near 4000.  
Tube PHONO preamp interference - RFI, EMI, bad grounding?
Yes aluminum foil would be fine as a shield.  
DSP vs. active analog crossover vs. passive analog crossover. What is your take?
IMO it's not a question of better but which approach appeals to their potential customers. I doubt very much a designer or anyone else could tell whether an analog crossover has been replaced with digital if the digital is programmed to mimic the...

First world problem solved by an amazing invention from the 70s.    
Using battery power to go off the City's power grid
No inverter in PS audio units. It appears to generate a voltage just above the input AC that follows the AC then uses a linear amp to make the output.

The powerline as a source is not at all ridiculous.  
DSP vs. active analog crossover vs. passive analog crossover. What is your take?
If you start with digital there is no way anyone could know if DSP is used or not. You would know if it was turned on/off but it is supposed to be doing something so I hope so. Can you hear an A/D and D/A conversion? With the right parts highly do... 
Can anyone tell me where the progress in audio went?
@tannoy56 from what I remember Bob tried to make his SS amp in that instance sound like his tube amp and failed and made a bad amp. A better comparison would be his big tube amp against a Krell or maybe something Purifi based. I would take the lat... 
Can anyone tell me where the progress in audio went?
I agree with the premise they want what sounds enjoyable @kingdeezie    However I disagree and believe it is lack of knowledge. There is a big big difference between having what you like, which we can assume most audiophiles have achieved to som...
