Phono Preamp Reviews

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.

At a hi-fi show in Germany a few years ago, an audio club had set up a room filled with a dozen well-known turntable/tonearm combos. I recall seeing the Clearaudio/Souther, Immedia RPM-2 and arm, VPI TNT Mk.IV/JMW Memorial, Basis 2500/Graham 2.0, Oracle/Graham, Linn LP12/Ittok, SME Model 20/SME V, and some others I can't remember, including a few not exported from Germany.

When we last heard from Englishman Tim">http://www.stereophile.com/interviews/990paravicini">Tim de Paravicini, whose EAR">http://www.stereophile.com/amplificationreviews/404ear">EAR 890 amp I reviewed in Stereophile's April 2004 issue, the veteran audio designer suggested that he could make a transistor amplifier equal in performance to any of his successful tube designs. Whatever else it may be, the new EAR 324 is my first chance to test that claim: a stereo phono preamplifier without a single tube in sight. It isn't TdP's first all-solid-state product: That would be the line-plus-phono EAR 312 preamplifier, introduced to no small fanfare a little over three years ago. For all intents and purposes, the 324 is a standalone version of the phono section of that $18,000 flagship: The designs are virtually identical—excepting, of course, their casework and power supplies.

In 2018, Micha Huber's HiFiction AG, manufacturer of Thales tonearms and turntables, assumed control of EMT Tontechnik, taking over EMT's cartridge business including development, production, repair, and international distribution—with the exception of the EMT broadcast cartridge line for the EU market, which is still distributed by EMT Studiotechnik out of the company's original Black Forest home in Mahlberg, Germany.

The original plan, back in mid-2004, was to audition an entire Ensemble system and then review the individual components over the next two years. Most audio companies produce lines of matching products, but Ensemble takes it a bit further, with a modular approach and extensive commonality of everything from chassis to circuit boards. They firmly believe that everything affects sonic performance, and their approach helps ensure a consistent sound throughout their line.

Modern hi-fi is little more than a way of getting electricity to pretend that it's music. Of course, good source components remain all-important, and even if loudspeakers are imperfect, most of us can find one or two that suit our tastes, if not our rooms and the rest of our gear.

When Stereophile publishes followup reviews of various kinds in the print magazine, we add the followup as a "child page" to the full review. That means that they don't appear on the website's home page and might get missed. The October 2020 issue included three followups: of the Boulder 2108 phono preamplifier, the Weiss DAC502 D/A processor, and the IsoAcoustics Gaia loudspeaker isolation feet.
