The least expensive model in Paradigm's Reference series, the Studio/20 loudspeaker is a rear-ported two-way dynamic bookshelf/satellite design, superficially identical to the powered Active/20 that JA reviewed last November. It features Paradigm's 25mm PAL pure-aluminum dome tweeter in a die-cast heatsink chassis, and a 170mm MLP mica-polymer cone in an AVS die-cast heatsink chassis with a 38mm voice coil. The crossover is third-order, quasi-Butterworth, said to be "phase-coherent." It features high-power ceramic resistors, film capacitors in all signal paths, and both air-core and steel-core inductors.
One of the first affordable loudspeakers I reviewed for Stereophile was the original Paradigm Reference Studio/20 bookshelf model, in the February 1998 issue (Vol.21 No.2). At the time, I felt that the $650/pair speaker was a breakthrough—although not completely devoid of colorations, its ratio of price to performance set a benchmark a decade ago. I kept the Studio/20s around for several years to compare with other bookshelf speakers I reviewed, and they remained listed in Stereophile's "Recommended Components" for several years after that. The Studio/20 is now in its fourth (v.4) iteration, so I thought I'd grab a pair to hear how they compared with current affordable bookshelf designs.
I am biased in favor of Paradigm loudspeakers. I've used them for 10 years; they offer good sound and good value, properties they share with a number of other Canadian makes who have taken advantage of Canada's National Research Council facilities in Ottawa. In fact, the first components I bought specifically for what is now my multichannel system were Paradigm Esprit/BP speakers, which had impressed me at a Stereophile show. When I took the step into multichannel and found that there wasn't a matching center-channel speaker for the Esprits, I replaced them with Paradigm's Reference Studio/60 v.2s. But while the smaller Reference Studio/20, and the larger Studio/100 have both been reviewed in Stereophile, the Studio/60 had not. The release of the v.2's successor, the Reference Studio/60 v.3 ($1699/pair), was an opportunity to fill that gap.
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.
It's common knowledge that manufacturers tune the sound of each DAC model. There are the facts of product design and marketing: inputs, outputs, case materials, price points. After that, what's left are the trade-offs of different circuit designs and filter options, which are chosen with careeach has a subtle yet telling effect on a DAC's sound. Most designers try to go from bits to analog with minimal deviation from perfect. But when you look at the measurements and listen closely, you realize that perfect is elusive. One has to make choices.
Oh boy, another new DAC review. Some folks think DACs, once you get past the features, all sound pretty much the same. I mean, it's just digital. Well, they're right. Pretty much. Just as two new cars of a particular make, model, color, and options package both look the same, sitting there on the lot.
But if you discover a ding in the door of one of them, where most folks still see only a new car, you now see the ding. It might have been there all along, undetected the first few times you walked around the carmaybe your buddy even had to point it out to you. It's insignificant in the scheme of all that a new car is, but once you've seen it, you always see it. Now you can easily tell the two cars apart, and we both know which one you'll drive home.
As with so many other things, from cell phones to soy milk, the idea of a portable MP3 player was something I at first disdained, only to later embrace with the fervor of any reformed sinner. But not so the idea of a high-fidelity iPod dock: Given that I now carry around several hundred high-resolution AIFF files on my own Apple iPod Touch, the usefulness of a compatible transport seemed obvious from the start. Look at it this way: In 1970, whenever I bought a music recording, I could enjoy it on any player, in any room in the house. In 2010, why shouldn't I enjoy at least that degree of convenience and flexibilitywithout resorting to a pair of tinny, uncomfortable earbuds?
In some ways, building an inexpensive yet musical two-way loudspeaker is a greater design challenge than creating a cost-no-object reference product. Although the latter is a much more complex endeavor, the venerable two-way box seems to bring out the creativity and resources of the designer. Rather than throw money at the product in the form of more expensive drivers, enclosures, or components, the designer of a low-cost two-way is forced to go back to the basics, rethink closely-held tenets, and rely on ingenuity and sheer talent to squeeze the most music from a given cost. Consequently, the inexpensive two-way is the perfect vehicle for designers to develop their skills. If one has mastered this art form, one is much more likely to achieve success when more ambitious designs are attempted.
Phiaton is the brand name used by the South Korean Cresyn Company. Wes Phillips reviewed Phiaton's conventional closed-back Moderna MS 400 headphones in January 2009 and was as impressed by the sound quality as he was by their appearance. The PS 200 ($249), the only in-ear headphone sold by Phiaton, also has a striking appearance: the black rear face, which is all someone sitting next to you in the subway will see, resembles the turbine blades of a fan-jet engine. There are two balanced-armature drive-units, with a passive crossover network.
I often receive letters from Stereophile readers. I've even gotten a few letters from female readers, one an attractive young lover of tube gear who sent me a picture of herself and [sigh] her boyfriend. But most are from people who are either thanking me for a specific review that resulted in a purchase and a satisfied buyer, or are suggesting products they'd like me to review. I frequently take the advice of writers of this second category; in fact, two of the inexpensive speakers I'll review in the next year were recommended by readers.
The buzz was all over the audiophile 'net. "Pioneer has a new bookshelf speaker that's killer for the money!"
Hmm, I thought. Pioneer. Speakers?
To be fair, I've had the Pioneer brand on my mind for well over 30 years. The company was my brand of choice for car-stereo electronics in the 1970s, for Dolby S cassette decks in the '80s, for DVD players in the '90s, and for plasma TVs in the '00s and '10s. I felt a bit guilty that I hadn't focused on the fact that Andrew Jones, the very same design guru who came up with Pioneer's TAD Reference One loudspeaker ($70,000/pair), had had a hand in designing a few two-channel speaker models starting at $99.99/pair. The audio gossip was all about the second model from the bottom of Pioneer's speaker line, the SP-BS41-LR ($149.99/pair). I thought I'd better get a pair and review them.
The loudspeaker coming under the microscope this month emanates from north of the border. The Canadian loudspeaker industry has benefited enormously in the last few years from having the measurement, testing, and listening facilities of Canada's National Research Council in Ottawa made available to it on a commercial basis. Unlike the US or even the UK, where a new speaker designer has pretty much to rely on his own resources, having to invent his own test procedure as well as design the product, the Canadian equivalent can have his loudspeaker tested under standard conditions, quickly indicating whether he is on the right track or not. (He still, of course, has to rely on his own talent to get on the right track in the first place or to get back on it if it appears that something is amiss.)
The British speaker manufacturer PMC Ltd. has built a professional client list seemingly as extensive as its almost mind-numbingly broad line of speakers. The i series alone includes 12 models, one of which is the DB1i ($1929/pair).
