RE: Do you realize

"There was an Acurus RS 10 preamp that measured the same as a Rotel and sounded very different but I can't recall the model number of the Rotel. Also an NAD measured very similarly to a Theta."

I am willing to wager that SOME of the measurements were similar but not all e.g they might the same FR into standard test load, but that's a whole 'nother matter. If they sounded different (i.e. not the observer's fanciful imagination), some of the parameters will measure differently. Basically preamps and amplifiers are mapped-out territory, you can develop various novel ways of building one, but measuring their performance is not rocket science.
