Solid State Preamp Reviews

Ah, domesticity. Just when I had the reference system sounding better than ever, the husband decided to relocate his electric keyboard and music stand, which had been positioned along the right wall of the detached music room, to the dining room in the main house. His reason was rational: While I did the reviewer thing in one space, he'd be free to practice keyboard and sing in another. But what was rational to him screwed with my reference sound and drove me to the brink of irrationality.

I start this review with a confession. I have consistently found that when I play CDs on a transport and feed the digital data via AES3 (AES/EBU) to a D/A processor, the music has more drive, particularly at low frequencies, than it does when I send the same 16/44.1 data to the same D/A processor via my network.

There has not been a conventional preamplifier in my main audio system for quite a while, because no multichannel preamp is available that's of high enough quality. Instead, I use the high-precision digital volume controls in my players and DACs and choose sources with a relay-based multichannel analog switch. Plus, I tell myself that no preamp can be more accurate and transparent than no preamp.

In the summer of 2021, MoFi Distribution's Jonathan Derda emailed me about the South Korean HiFi Rose brand. "This brand strikes me as being the spiritual successor to the original SlimDevices Transporter and Squeezebox Touch," he wrote. "We're all really excited about it."

Even as I was admiring some of the handsomest audio gear I'd ever set eyes on, my thoughts kept returning to equipment of a very different sort.

Flash back maybe 40 years to my one-bedroom apartment on Elgin Park in San Francisco during the period when I was whistling for my supper and performing Puccini's "O mio babbino caro" in the Emmy-nominated Peanuts cartoon, "She's a Good Skate, Charlie Brown." Cue the constant din of an elevated four-lane freeway, since demolished as a blight on humankind, which I tried to pretend was the sound of water in the accompaniment to one of Schubert's many "water and fish" songs.

I am certain the quality of life I live is determined by two factors: who and what I give my attentions to, and my ability to observe all that I encounter with an open mind. This approach to living has served me well—especially during this review of the Benchmark Media Systems HPA4 headphone amplifier ($2999).

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.
