The Surprising Audreal LP-2 Phono Preamplifier
Michael Fremer  |  Sep 10, 2012
Back in 2005 I reviewed what was then the $1500 Jasmine LP-2 MM/MC phono preamplier. It was a two box unit with an umbilical between the power supply and the signal path circuitry. The 70dB gain MC input was commendably quiet and the unit sounded pretty good but I couldn’t justify the performance for the price.

Liberty Audio B2B-1 phono preamplifier
Michael Fremer  |  May 24, 2012
The all-FET, class-A, B2B-1 phono preamplifier ($1749), made in the US by Liberty Audio, is beautifully built inside and out, and comes in a heavy-duty aluminum chassis with a baked-on crackle finish and a 3/8"-thick, black-anodized faceplate. The overall build quality and physical appearance suggest something that costs more than $3000, which is probably what it would cost were it sold through retailers and not factory direct. It comes with a two-week return policy.

Precision Transducer Engineering MMMC Phono Preamplifier
Michael Fremer  |  Feb 13, 2012
The phono preamplifiers reviewed this month are both affordable ($400–$1960) and highly accomplished, and the most expensive of them offers versatility that's unprecedented in my experience. Three of them are designed to be used only with moving-magnet, moving-iron, and high-output moving-coil cartridges, so I installed Shure's V15VxMR cartridge in VPI's Classic 3 turntable and listened in MM mode to all of them, beginning with the least expensive.

Parasound Halo JC 3 phono preamplifier
Michael Fremer  |  Oct 24, 2011
According to Parasound's founder and CEO, Richard Schram, the Halo JC 3 began as a phono-preamp retrofit for the JC 2 line stage, with separate small circuit boards for each channel. The smaller the board, the better, Schram says, so as to attract less noise than do larger boards, whose many copper traces can act as antennas.

Abbingdon Music Research PH-77 Phono Equaliser

Why bother with three phono preamps most of us can't afford? For the same reason the enthusiast automobile magazines cover the newest Ferraris and Lamborghinis: just reading about them is fun.

Vitus Audio MP-P201 Masterpiece Series phono preamplifier
Michael Fremer  |  Sep 23, 2010
This massive, two-box beauty from Denmark costs $60,000, and I wish I could tell you it wasn't really better in most ways than the already outlandishly priced and sonically superb Boulder 2008. I can't.

Phono Preamp ReviewsVinyl Digitizing Tips
Pure Vinyl LP recording & editing software
Michael Fremer  |  Aug 19, 2010
As long as you're spinning an LP for your listening pleasure, and if digitizing it at a resolution of 24-bit/192kHz is transparent to the analog source, why not record and store the LP on your computer at that high sampling rate for future convenient playback via iTunes or for iPod use, or for burning to CD-R? And, while you're at it, why not record the LP unequalized and apply the RIAA curve in the digital domain, where you're not dependent on capacitors and resistors that are imprecise to begin with, and can drift over time? With no drift of phase or value, the virtual filter's results should be better than with any analog filter. And in the digital domain, you can program in any curve known, and select it at the click of a mouse. Aside from the sweat equity invested in programming it in the first place, it wouldn't add a penny to the program's cost.

Seta Nano phono preamplifier
Michael Fremer  |  Aug 19, 2010
The minuscule electrical output of an analog signal from a moving-coil cartridge needs to be boosted before it can be converted to digital and equalized in the digital domain. Of course, you could use your current phono preamplifier and record an equalized signal to hard disk, but then you wouldn't get to experience Pure Vinyl's digital RIAA correction—nor would you be able to avail yourself of all the equalization curves provide by Pure Vinyl, of which there are almost too many to count.

Nagra BPS phono preamplifier
Michael Fremer  |  Sep 24, 2009
This tiny, lightweight, battery-powered jewel is loosely based on Nagra's VPS phono stage that I 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.

Lamm LP2 Deluxe phono preamplifier
Michael Fremer  |  Sep 18, 2009
In an ideal world, I'd have every phono section I've reviewed in the past 16 years on hand to compare with these three and with all that arrive in the future. But because I have a life, I don't, and I wouldn't even if I could, though some readers (and one retailer) have insisted that that's the only way that I could possibly be of any use to them. Ha! And for those who are concerned that I've neglected the Manley Steelhead, not so! It's still my reference.

Audia Flight Phono preamplifier
Michael Fremer  |  Aug 31, 2009
I first spotted Audia Flight's exquisite-looking two-box phono preamplifier ($6100) at last year's Hi-End show in Munich, and now that Musical Sounds is importing Audia Flight gear, a review of the Phono seemed a good idea. I know nothing about Audia Flight or the designer, or what Italian audiophiles think of them, but the more time I spent with the versatile, exquisitely built Phono, the more I liked everything about it.

Nagra VPS phono preamplifier
Michael Fremer  |  Sep 17, 2008
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.

AQVOX Audio Devices Phono 2Ci phono preamplifier
Michael Fremer  |  Jul 29, 2008
The German company AQVOX Audio Devices has produced an innovative moving-coil/moving-magnet solid-state phono preamplifier, the Phono 2Ci, that's as intriguing for its technology and performance as it is for its relatively low price: $1400. The zero-feedback, op-amp–free circuit uses a compact switch-mode power supply that's built into the chassis and features conventional voltage gain for moving-magnet cartridges via its RCA jacks, and current gain for moving-coil cartridges through the balanced XLR inputs. Rear-panel switches select between RCA or XLR inputs and offer a convenient ground lift. Either the single-ended or the balanced outputs can be used with either input. Unfortunately, the tight spacing of the RCA input and output jacks, which are mounted on the circuit board, will somewhat limit your choice of cables: Pairs of thick-barreled plugs will have difficulty fitting.
