Phono Preamp Reviews

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.

The other day it occurred to me that the main difference between audiophiles and more reasonable adults isn't our gear. Plenty of people have impressive hi-fis simply because they can afford them and are running out of things to buy. No, what makes someone an audiophile is the willingness to sit down in front of a pair of speakers (or with a pair of headphones clamped over their ears) and focus the entirety of their attention on listening.

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.

When we last heard from Englishman Tim de Paravicini, whose 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.

What's this? A review of a $3000 moving-coil step-up transformer in this digital day and age? Yep. Although the market for such a product is small, the fact that the Expressive Technologies SU-1 step-up transformer enters previously uncharted state-of-the-art territory warrants these pages of editorial space. Furthermore, LP playback appears to be alive and well at the upper end of the high-end spectrum, a market segment addressed by the SU-1 (footnote 1).
