Manley Labs Steelhead phono preamplifier

The Manley Steelhead tube MM/MC phono preamplifier was first demonstrated at the 2001 Consumer Electronics Show. Nine months later, my long-promised review sample of Eveanna Manley's new baby was delivered. While Ms. Manley may have given birth to the audacious product, it was conceived by the company's chief hi-fi designer, Mitch Margolis.

Moon 891 streaming preamplifier

No fewer than eight boxes, powered by six after-market power cables, comprise my current reference front-end. As much as separate boxes can afford superior isolation and provide far more room for visionary engineers to work their magic, the advantages of a single box, which requires a single power cable and far fewer after-market interconnects, are obvious.

Enter Simaudio's Moon 891 network player/preamplifier ($25,000; footnote 2). Also called a "streaming preamplifier,"it includes a DAC that converts PCM and MQA files up to 32/384 (with 24-bit files upconverted to 32-bit) and DSD files up to 256. It also includes what Simaudio company co-owner Costa Koulisakis describes as "a fully configurable" MC/MM phono stage. Both theoretically and practically, it's an ideal solution for someone with space and/or budget constraints.

Mytek Digital Brooklyn Bridge II Roon Core preamplifier

The concept of streaming digital music files over distances great (as with internet-streaming services like Spotify, Qobuz, Tidal, etc.) and small (from a home-PC hard drive, NAS, or networked music server) became mainstream only recently. But it was already brewing during the late 20th century, with people illegally downloading low-bitrate MP3 files made from CD rips and coming close to killing the recorded-music industry.

That wasn't streaming exactly, or not in the current sense, because the files needed to be downloaded, stored locally, then either played out of a computer or loaded onto a portable player, but from that point forward it was a steady march to the streaming-dominated present.

Never mind Napster—the first subscription audio "streaming" service was one you probably wouldn't think of: Audible, the audio book service now owned by Amazon, which started up in 1995. I did beta testing and editing work for early-days Audible, and around that time, I started loading up home-ripped MP3 files on a pocket-sized Rio MP3 player (which by then had replaced Audible's proprietary player), using it in place of a portable CD player. This led to experiments with a PC music library/player running Linux, controlled by a Handspring PalmOS device connected to the stereo system via a Sound Blaster 16 card.

NAD PP 3 digital phono preamplifier

Even Mikey Fremer is surprised at vinyl's current popularity. Some pundits postulate that eventually CDs will die out, and we'll be faced with the choice of LPs or downloads. (I hope not. I'm just getting used to CDs.) With abundant sources of new pop releases and a wide range of reissues on vinyl, and a variety of used LPs, every audiophile should own a turntable. And with the availability of affordable turntables such as the Pro-Ject Debut III, which I reviewedhttp://www.stereophile.com/turntables/pro-ject_debut_iii_record_player"…; in the February 2010 Stereophile, the cost of entry to VinylLand is not very dear. The problem is that so few entry-level integrated amplifiers and receivers available today include phono stages. (The Marantz PM5003, which I reviewedhttp://www.stereophile.com/integratedamps/marantz_pm5003_integrated_amp…; in the January 2010 issue, is a notable exception.)

Nagra BPS phono preamplifier

This tiny, lightweight, battery-powered jewel is loosely based on Nagra's VPS phono stage that I reviewed">http://www.stereophile.com/phonopreamps/908nag">reviewed in October 2008 but uses bipolar transistors instead of tubes. The bottom of the company's familiar brushed-aluminum case has a grippy rubber material die-cut to spell Nagra. It's intended to keep the preamp from sliding, but stiff cables will have the BPS hanging in the air if you're not careful. The BPS costs $2399.

Nagra VPS phono preamplifier

Not that many years ago, it seems, every sound crew in Hollywood and around the world recorded production sound using a compact, open-reel analog tape recorder made by Nagra. The first iteration of the Swiss-made machine appeared in the early 1950s. Shortly thereafter, with the addition of an inaudible recorded tone that allowed easy syncing to picture, the Nagra recorder became the industry standard, and remained so through the 1980s. To this day, Nagra's line of audio products retains the look of those early recorders.

Pass Aleph Ono phono preamplifier

If compact discs are so damned dynamic and vinyl is so dynamically limited, why do they sound just the opposite? Why do LPs sound so "live," so explosive, so "there," and CDs so dead? Even the best CDs usually sink to second-rate when you switch to their vinyl versions. I've heard it, you've heard it. Only those in deep denial, those who refuse to listen, don't. They'd rather read the published specs and consider the actual listening some kind of mass delusion among Luddite LP fans.
