Integrated Amp Reviews

The Rega Couple interconnect ($150/1m pair) comes in a plastic pouch rather like a Ziploc veggie bag—just the pouch and a printed card. How much could the packaging cost? Ten cents?

Creek Audio founder/designer/co-owner Michael Creek is a quiet, friendly, unassuming man. Unlike some ego-driven electronics designers who tout their products very loudly from their pulpits, Michael Creek has been quietly designing high-quality, musical, and affordable integrated amps in black-metal boxes for nearly 20 years. His target market is the passionate music-lover who wants something a notch above an entry-level NAD or Rotel receiver, but whose bank manager would frown on splurging on electronic separates.

Having evaluated any number of integrated amplifiers in the past year or so, I've repeatedly been impressed by the ways in which designers build versatility and sonic distinction into their single-box designs. In matching those that sounded and measured the best—such as the tubed E.A.R. V20 (October 1999) and the solid-state Magnum">http://www.stereophile.com//amplificationreviews/329/">Magnum Dynalab MD 208 receiver (January 2001)—with appropriate speakers and source components, I was able to attain high-resolution musicality with a minimum of fuss. Crave high-end sound but require even less complexity? You could dispense with interconnects altogether by integrating a high-quality CD player into a remote-controlled receiver, as Linn has with the diminutive Classikhttp://www.stereophile.com//digitalsourcereviews/307/">Classik; that I reviewed last November.

Musical arguments in favor of separate components are compelling and well-documented. But there's also something musical to be said about reducing the number of power sources, keeping signal paths short and direct, and hard-wiring connections between components rather than employing multiple sets of interconnects. So while a designer must inevitably confront certain tradeoffs, the explosive growth and popularity of single-box products in the past few years contradicts the received wisdom passed down by some of the more sniffy audiophiles: that such unduly proletarian products are terminally compromised in terms of absolute levels of music reproduction.

In the ongoing audiophile debate over the relative merits of solid-state vs tube amplification, compelling cases can be made for the overall musicality of both methods. And while there's a lot to be said for the dynamic headroom, bass focus, clarity, frequency extension, and silent performance of solid-state gear, it's funny how much you can come to miss the aural verities of tube electronics after a prolonged absence.

When I learned that Madrigal Audio Labs was marketing their first integrated amplifier, the Mark Levinson No.383, I felt this was a big change for the Connecticut company. Mark Levinson literally started the high-end marketing revolution back in the early 1970s by manufacturing cost-no-object separate amplifiers and preamplifiers. The purist designs had one overriding rule: employ the simplest circuit path possible. Each amplifier or preamplifier used only individual circuit-board components (no integrated circuits) and had a minimal number of controls, eschewing elaborate switches and tone controls. Mark Levinson Audio Systems and its successor, Madrigal Audio Laboratories, has continued this philosophy of separate components for the past 25 years.

Why would a sharp mind offer a $15,000 integrated digital amplifier to a reviewer who has been characterized in the audio press as the "self-proclaimed Analog Messiah" and a "hyper-Luddite"? That's the first question a self-centered reviewer asks himself. Yours might be: "A $15,000 integrated amplifier from...Sharp?"
