The most criminal practice in the speaker industry revealed!! Keep reading
Who's going to verify the manufacturer's measurements aren't biased?  
Total bass suck out at 40hz
Is the test tone playing at 40hz or is it a dead track? Try another speaker.If the file is good, then check to see if your woofer is moving at 40 hz. This is why I always measure frequency decades one foot from each speaker before I measure at the... 
Dynaco Stereo 120
The output transistors are wired to the capacitor positive, that white wire connected to the negative terminal of that (output) capacitor, then wrapped around the capacitor in series to the speaker terminal. The cap blocks dc and the wire is an in... 
The blackest black paint ever
It's like how much more black could that be? The answer is none. None more black. 
Siemens 20 amp breaker for dedicated lines
Why Siemens? I assume you have a Siemens or Murray panel. If not, use the breakers recommended for your panel.You do not need GFCI for a music room.You many need an arc fault breaker if required by local building codes, if you are doing new constr... 
Leave tube amps always on?
The way I read it is his reasoning is based on environmental concerns and not the life of the tubes. I have had a Cat preamp for over 25 years and there is no difference in sound after 20 minutes of playing no matter how long it is left on. Based ... 
Whats a good economical way to test the electricity on a circuit?
Oscilloscope for time domain, FFT analyzer for frequency domain, and LISN for what comes out of the power cord of equipment. They are not cheap but that's the only way to visually see/measure noise. 
adjustable "fixed" bias amps
Sounds to me that's for both tubes and the bias is measured at the power supply takeoff. 
Dedicated line: 10 gauge solid core or 8 gauge stranded
On the 10/3 romex, I do not use the bare copper grounding conductor; I cut it flush to the jacket at both ends. Use the red wire for grounding to the receptacle screw and the panel ground bus (don't forget to wrap the red insulation with green ele... 
Does the first reflection point actually matter??
Eric:Try the "Circling Tones Test" with and without the first reflection side wall panels: https://www.yarlungrecords.com/sonorus/ In my room, the sound is a full 180 degrees with the GIK panels and a little less without. Noticeable. 
Dedicated line: 10 gauge solid core or 8 gauge stranded
I use 3 wire 10 gage Romex because the wires come pre-twisted. This goes a long way to reducing common mode noise being picked up from the EMI producing computers, routers, modems, iphone chargers, alexas, etc.If the circuit wire hot, neutral and ... 
Isolated ground for 20 amp
Receptacles with isolated grounds are still grounded. The ground is isolated from the grounding system downstream of the panel. For example, if you install a receptacle to a metal receptacle box you tap from another circuit, the grounds are common... 
Thiel Owners
As a Thiel 3.6 owner for over 25 years, I'm considering replacing them with either the 3.7 or 7.2. Found a pair of CS7's that were converted to the 7.2 but the cement baffle has a horizontal crack from each  side of the midrange to the edge. Is th... 
Schiit Yggsdrusil - with New Unison USB
My two cents is Yes. Prior to the Unison the Yggy sounded slightly better through my Theta Data Basic with RCA than the Aurender N100H and USB. With the Unison, the differences vanished and I prefer the Aurender/USB. The real improvement through t... 
Why are there so many wooden speakers?
If a speaker weighs as much as a duck... it is made of wood... and therefore... a witch!
