Integrated Amp Reviews

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.

With Peachtree Audio's new nova125 integrated amplifier, most decisions are made for you.

Need a DAC with three S/PDIF inputs (two coax, one optical)? An asynchronous USB DAC? A line stage? A tubed output buffer? A power amp that should be able to drive even difficult speaker loads? Remote control? You've got them all for $1499. Just add speakers. (I assume you have a laptop computer and several disc spinners.) You may want a separate phono stage, because there is none onboard.

One year ago almost to the day as I write, Peachtree Audio invited me and other members of the audio press to the New York City retail shop Stereo Exchange, where various announcements regarding the brand were bundled, by the company's Jim Spainhour and David Solomon, under the virtual banner "PEACHTREE 2.0." Among the news: Peachtree, based in Bellevue, Washington, would now be manufacturing their nova integrated amplifiers in Canada—the company's previous offerings were all made in China—and they'd signed up a new design and engineering team.

Does the modern audiophile want a sleek, compact, powerful, remote-controlled, microprocessor-driven, two-channel integrated amplifier? Perreaux Industries, based in New Zealand, thinks so. They've designed all that, plus good looks and impressive build quality, into the R200i. Despite its relatively small size—4.1" tall by 16.9" wide by 13.4" deep—the R200i packs a punch. It's rated at 200Wpc into 8 ohms and 360Wpc into 4 ohms, yet it weighs just a fraction under 30 lbs.

Despite its name, the Panache is not made in France, but here in the States, by Portal Audio, headquartered in Charlotte, North Carolina. The company is owned and run by Joe Abrams, a longtime veteran of high-end hi-fi who was once closely associated with Threshold.

Ever since I reviewed PrimaLuna's ProLogue Premium, for the June 2012 issue, it has been the model I would turn to when I wanted a moderately priced integrated amplifier to try with a new speaker. It never disappointed me, and never seemed outclassed, even when the speaker was the MartinLogan Montis ($10,000/pair). At $2399, the ProLogue Premium to me represents the "sweet spot" for systems in the range of $4000–$10,000 or higher. Although its 35Wpc may not be enough for some speakers (depending on the room and personal preference), I never had any such problem, regardless of whether the speaker had a built-in powered subwoofer (eg, the Montis or the GoldenEar Technology Triton Two) or was a passive design (Wharfedale's Jade 7 or Focal's Aria 936). With differences noted depending on whether EL34 or KT88 output tubes were used, the ProLogue Premium delivered sound that was always smooth and musically involving.

"Hybrid" technology—specifically, mixing tubed and solid state in the same amplification device—stirs a deep desire for many enthusiasts. It has the potential to embody a perfect blend: the tonal liquidity, presence, and spaciousness of tubes coupled with the power and dependability of solid state. It's potentially an end-game technology.

Still, I have long remained skeptical. I am, I confess, a certain kind of audiophile, a blend of purist and traditionalist. I favor older technologies and simpler circuits. Amplifiers—including integrated amplifiers—should be tubed, input to output. Rectification? Tubes of course. I've even entertained OTL designs—the idea of them at least, though my experiences have been mixed.
