Sorry, missed it among the chaff. But I was really going down the "proof of listening" DBT path that is so maligned.

This is all due to Ohm's Law. The reason fuses appear to be directional is that they are not perfectly cylindrical and the fuseholders...

There is a random element in any measurement. Nothing is perfect, including a measurement system. It has finite resolution, dynamic...

The measured difference is tiny and somewhat random as one would expect making milliohm resistance measurements. It will be swamped by...

How Does the Output Voltage of DAC Affect the System's Sound Quality? Does it Matter if One is Using a Quality Preamp?

Short answer: I don't know. But note the transformer's max input spec does not matter unless you are pushing it; what you need to know...

400 W into 8 ohms is 56.57 Vrms and given 28 dB(25.12 V/V) gain requires 2.25 V for full-scale output. I would try the DAC's 2 V output...

What is the input sensitivity of your amplifier? The equations get a little complicated, but I'd start by choosing the DAC output that...

Specs for audio components are usually Vrms (and Arms for current). Power is normally average power in W (there's no such thing as rms...
