Before starting this review of Rotel's Michi P5, the 60-year-old, Japan-based audio company's recent preamplifier design, I thought it appropriate to consider "What is an audio preamplifier? What should it do?" There are plenty of opinions to be found at stereophile.com:

"What a preamp ought to do, apart from changing volume and switching sources, is as little as possible," wrote Stereophile Editor Jim Austin in his 2017 review of the PS Audio BHK Signature preamplifier.

Ever since I stopped using my Audio Research SP10 preamplifier in the early 1990s—its eight phono-stage tubes used to get too noisy too quickly—I tried a variety of standalone phono preamplifiers. Seeing the most service through the 1990s and 2000s were, first, a Mod Squad Phono Drive EPS, then a Linn Linto, both of which I purchased. But when I measured Channel D's Seta Model L, which Michael Fremer reviewed in the August 2010 issue, the Linto was pushed to one side. The battery-powered Seta L (footnote 1) had the lowest noise and distortion I had encountered in a phono preamplifier, and I eventually bought the sample I had been sent for a follow-up review in 2013.
