Integrated Amp Reviews

As a young music lover, I never knew there were such things as separate preamplifiers, amplifiers, and FM tuners. All I knew was that if I wanted to play music from my CD player, hook up my VCR to my stereo, or listen to the radio, I needed that magical device: a receiver. It was all I ever wanted.

Whether one was surprised, in 2010, by the success of Peachtree Audio's iDecco may have more to do with age than anything else. My peers and I wondered, at first, who would want their high-end integrated amps to come bundled not only with digital-to-analog converters but with iPod docks, of all things; at the same time, younger hobbyists wondered who in the world still wanted their integrated amps to contain phono preamplifiers. (Respect for the elderly, myself especially, prevents me from adding "and mono switches.") Color me chastened.

Since its founding just over ten years ago, Mission Electronics has grown to become one of the largest "real" hi-fi companies in the UK. Although their product line originally consisted of three relatively conventional loudspeakers, it rapidly grew to encompass high-end pre- and power amplifiers, cartridges, tonearms, and turntables, and, in the mid 1980s, a system concept based on CD replay and relatively inexpensive electronics: the Cyrus amplifiers and tuner.

I can imagine the gaiety and mirth that filled the halls of the electronics industry in the 1950s, as engineer after bespectacled engineer realized that the transistor would soon consign to the outposts of oblivion those ancient technologies that had preceded it. Before long—surely no more than a decade—the hated vacuum tube would vanish from the Earth, along with the tube socket, the tube tester, the tag board, the high-voltage rail, and that lowest rascal of them all, the output transformer. What a jubilant time!

I can't imagine what went wrong.

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.

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.

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.
