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.

In place of my usual Wilson Alexxes, a pair of small (though very fine) two-way speakers has been in my system this past month: the Marten Oscar Duos I review elsewhere in this issue. Without my usual reference speakers in the system, I didn't feel comfortable covering anything that affects sound quality for this column, so, with the exception of one item—the first—this column covers accessories that don't require sonic evaluation.
