Well, Mr. Humber and the Company feel that this is the most important component of a quality Audio system. I very much disagree with the whole premise and I disagree at two levels.

First, I feel that the concept of Linearizing of sources preamplifier is very faulty and absolutely not necessary. This reminds me that crazy preamp where each input has own flavor of driver tube. I do welcome the fixed RIAA corrections at Phonostage but to have it at line level preamplifier is ridicules and serve purely self-entertaining purpose.

The second is the means of Linearizing. Manuel claims that he has subtractive phase liner filtration. The phase liner filtration variable filtration? Good luck with that. Any filtration is a delay. Even if you run the main signal none-filtered then soon or later he need to sum the none-filtered main signal with the delayed branch. It is not a single point of delay but the delay wary with octave. So, his assurances that it is not EQ but completely different this is not really warranted.

It is very possible that this FM Acoustics preamp is a fine unit and that it does better than other EQ solutions but why the EQ solution shale be implement in preamps is beyond me. Should a person to “correct” bad recordings, the room problems or expectation problems? I do not know the answer.
