Pass Laboratories XP-30 line preamplifier
It was the strangest thing. In the fall of 2008 I was comparing Ayre Acoustics' then-new KX-R line preamplifier with no preamplifier at allI was feeding the power amplifier directly with the output of the Logitech Transporter D/A processor. (Levels were matched for the comparisons, of course, made possible by the fact that the Transporter has a digital-domain volume control.) Being a rational being, I knew that the active circuitry of a preamplifier, as well as the extra socketry and cables, would be less transparent to the audio signal than a single piece of wire. I wanted to determine by how much the Ayre preamp fell short of that standard.
Pass Labs XA60.5 monoblock power amplifier
Whereas the Pass Labs preamplifiers are designed by Wayne Colburn, the power amplifiers are the work of company founder and high-end audio veteran Nelson Pass, who even lays out his own circuit boards. The X-model amplifiers, beginning with the X1000 in 1998, were the first implementation of Nelson Pass's patented Supersymmetry topology (see "Nelson Pass on the Patents of Pass"). The XA series, which debuted in 2002, combined Supersymmetry with the single-ended class-A operation of the Aleph series. The XA.5 models offer detail improvements over the XAs.
Pass Labs XP-27 phono preamplifier
One of the pleasures of reviewingand also usingproducts from Pass Laboratories is an encounter with Nelson Pass's writing, which can usually be found in the owner's manual and is always competent, insightful, and sometimes funny. How often do you get real pleasure and insight from reading an owner's manual?
Pass Labs has a lot of owner's manuals online. Reading through one, I encountered the following passage; you'll find the same or similar language in other manuals and on the Pass Labs website. I present it not only because I admire it and agree with the philosophy it expresses but also because it captures the spirit of the product under reviewthe XP-27 phono preamplifier ($12,075 in silver)at least as I've experienced it during an extended review period. Here it is, quoted at length with some slight adjustments to make it consistent with Stereophile's editorial style...
Pathos InPoL Legacy integrated amplifier
Back when gasoline had lead in it and amplifiers came with circuit diagrams in the back of the manual, there was an unspoken understanding that power meant weight. A professional camera was a Graflex Speed Graphic or a Hasselblad 1000F, built like a small battleship and nearly as heavy. Powerful car engines were cast-iron V8s with cylinders you could stick a fist in. And of course, serious amps had transformers that could double as boat anchors.
These days, amplifier design often emphasizes efficiency. Class-D amps in particular have come a long way. Many are terrific, and they're undeniably practical. But there's still something uniquely satisfying about a design that prioritizes timeless expression over economy of electricity or space.
The Pathos InPoL Legacy, a class-A design, is unapologetically massive and so gloriously overbuilt that moving it requires a tactical plan and a chiropractor.
Philips LHH1000 CD player
Externally, the LHH1000 came as a bit of a surprise to these jaded eyes, over-familiar with plain black or brushed-aluminum boxes. Each enclosure is finished in an almost white, anodized finish, with greenish-gray endcaps (made from zinc alloy, I believe) painted with a nubbly, crackle finishan attractively utilitarian styling with shades of military-surplus radio equipment, nicely set off by subdued blue fluorescent readouts. Internally, the units are constructed to audiophile standards. The transport uses Philips's top CDM-1 mechanism, which is fabricated from diecast aluminum, compared with the plastic CDM-4 mechanism which appears in less expensive and less well-specified players. The loading tray, too, which is made from metal, has a reassuringly solid feel to it.
Piega Coax 811 Gen2 loudspeaker
It's funny how we discover some music in unexpected, twisting ways. A friend recently sent me the real estate listing for a beautiful home in Deer Isle, Maine, about an hour from where I live. I gawked at the pictures and calculated I'd need to work for Stereophile for another 127 years before I'd have enough dough to buy it. Then I noticed something unusual on one of the walls of the place: lots of gold records. Google helped me figure out that the house had belonged to the late singer-songwriter Dan Fogelberg. I knew the name but was unfamiliar with his music. Minutes later, I was playing the studio version of "Nether Lands," seemingly named after my country of birth. A beautifully orchestrated piece with restrained woodwinds and soaring strings, it reminded me of the best of Van Dyke Parks and of some postPet Sounds Brian Wilson songs. I played it straight through three times.
Part of the reason I was so smitten with the recording lay in the engaging, naturalistic presentation it received from the handmade-in-Switzerland Piega Gen2 811 floorstanders ($30,000/pair) that had just made their way to my listening room.
Playback Designs MPS-5 SACD/CD player
Playback Designs was founded less than three years ago. However, with the release in 2008 of its MPS-5 Music Playback System—a slim, full-featured SACD/CD player and DAC that costs $15,000 and is built in the US—the company has since established itself as a significant player in high-performance digital audio.
Plinius Reference A-150 power amplifier
When Jim Austin offered the Plinius Reference A-150 stereo amplifier ($14,995) for review, it felt like a welcome blast from the past. Plinius has, lately, maintained a low profile in the US, likely due to several changes in US distributorship...Under the auspices of Ralph Abramo and California-based Plinius Audio Sales and Repair, Plinius's US profile seems to be rising again.
Proceed CD Library
I think I've finally figured out the secret of Stereophile's success. You, cherished reader, don't read this mag because it's chock full o' reviews of tantalizing audio gear (even though it is). And you don't read this mag because JA and RL strive so hard to keep the literary quotient as hi as the fi (even though they do). And I know you don't read this mag cuz trusting yer own sensory input is a mighty scary proposition indeed so you look to Stereophile as to a Holy Bible that eases your Earthly burden by telling you, Ah say Ah say TAILING YEW what to buy (do you?).
Raidho TD3.8 loudspeaker
In my high-school days, I visited a friend whose well-to-do dad proudly demonstrated his new Quad ESL system for us. First up was a recording of a man with heavy footsteps traversing the space from left to right. Next came a speeding police car, siren engaged, complete with Doppler tail. I found it impressive, and a little lame at the same time. My friend and I, in love with our own artsiness, preferred Fear of Music by Talking Heads and Drums and Wires by XTC, or (in a pinch) U2's Boy.
It wouldn't have occurred to me that I'd ultimately derive frequent joy from listening to sound effects (though in my case they're usually integral to the music, not apart from it). When I hear Yosi Horikawa's bouncing marbles on Wandering, I prick up my ears and smile. A panting dog on Holly Cole's Temptation, an overhead hovercar on the Blade Runner 2049 soundtrack ... bring it on. A babbling river on Andrew Bird's Echolocations; seed pods on Tom Waits's Blood Money; liquid splashes and crinkling paper on Felix Laband's Dark Days Exit ... yes, please. I don't care if it's a little gimmicky. It's also sensual in the original meaning of the word, an aural pleasure.
The Raidho TD3.8 speakers that, after three months, just departed my home, do the trick of conjuring points in space with great acuity.
