Integrated Amp Reviews

Integrated amplifiers are hot. I don't mean in the literal sense—although having a preamplifier and stereo power amplifier in the same chassis usually results in higher running temperatures—but in the metaphorical one. Once viewed as the type of component that no serious audiophile would consider buying, integrated amps have made a comeback in popularity and prestige. Consider: the October 2006 "Recommended Components" issue of Stereophile listed 29 integrated amps, whereas the October 2011 issue lists 40. Stereophile's 2010 Amplification Component of the Year award went to an integrated amp, the Audio Research VSi60, beating out a host of heavy-hitter preamps and power amps. The 2012 Stereophile Buyer's Guide lists 400 integrateds.

B.M.C. Audio GmbH (the initials stand for Balanced Music Concept) designs its high-performance audio products in Germany, where the company was founded in 2009, and has them manufactured in its own wholly owned factory in China. The design team is headed by Carlos Candeias, whose earlier designs included a belt-driven CD transport for C.E.C. and, for Aqvox, a high-performance, current-gain–based, balanced phono preamplifier that's reasonably priced. These have won him a lot of attention, and made him something of a celebrity in certain sectors of the audiophile world.

Stereophile has reviewed two integrated amplifiers from Chinese manufacturer Cayin in the past: the A-50T, which I wrote about very positively in March 2008, and the A-300B, which Art Dudley reviewed in February 2007. So when I read about Cayin's $2195 SP-10A integrated amplifier, which has a wood-covered sleeve, just like the old Marantz and McIntosh gear and offers 38 watts of push-pull power, in our coverage of the 2008 CES, I put in on my must-write-about list.

In my last column, in November 2011, I mentioned that preamplifier-processors are generally at a price disadvantage in comparison to the same manufacturer's A/V receivers. The economies of scale almost ensure this. Typically, to design a pre-pro, a manufacturer uses one of its AVR models as a platform; the result is most distinguished from its parent AVR by its lack of power amplifiers.

The very first amplifier I bought was a Harman Kardon PC-200, aka The Prelude. It was a 10Wpc integrated, but I chose it over the competition for some of the same reasons that the HK 990 has appealed to me. Almost all amps back in the1960s had a plain cake-pan chassis with tubes, capacitors, and transformers studding the top. Integrated amps had the standard four knobs on the front for input selection, volume, bass, and treble. The HK PC-200 had an enclosed black chassis cage that formed a graceful cowl over the brushed-copper front panel and the six matte-black knobs: for Input selection (with three phono turnover settings), Volume, Bass, Treble, Loudness contour, and Treble rolloff. In addition, it had a Rumble Filter switch. The PC-200 was not only more beautiful than the rest of the push-pull competition powered by EL84 tubes, it also had more useful features. (Take that, you fans of the Grommes Little Jewel!). Over the decades, H/K products have always been stylish and innovative, but in today's fractured marketing world, most such creative energies are applied to audio/video receivers and lifestyle products.

Let's not beat around the bush: this is what an amplifier is supposed to look like. The silver front panel contains over a dozen knobs and switches, yet somehow avoids seeming cluttered. The solid wood cabinet wouldn't look out of place next to Hugh Hefner's cognac decanter. And the controls! The SQ-38u is as full-function as they come ("as they used to come" would be closer to the truth), with a Balance knob, separate Bass and Treble Tone Controls, a low-frequency cutoff (aka "rumble") switch labeled Low Cut, a Mono/Stereo switch, and a mute button; plus switching and connectors for two pairs of loudspeakers. Everything but curb feelers.

In a perfect world, I would own the following: one good turntable (footnote 1), one good tonearm, one good pickup head, one good step-up transformer, one good integrated amplifier, and two good loudspeakers. And some decent cables. That's all, except maybe a home and a dog and some records and some books and one good guitar.
