Today's New York Times carries a brief obituary notice of the passing of audio innovator, Peter Pritchard, on August 23 in Austin, Texas at the age of 83. Peter founded Audio Dynamics Corporation in New Milford, CT in the early 1960's. His original ADC-1 ("Tip mass: 0.6 mg. Compliance. 20x10^–6cm/dyne, all directions. Playing weight: 1 gram or less in top quality arms") was a breakthrough product. Indeed, all ADC pickups were notable for their extremely high compliance and low tracking forces and he pursued this approach through a series of successful designs including the well-known ADC-10, ADC-25 and XLM cartridges. They were all based on his "induced magnet" principle, which derived from the older GE variable-reluctance cartridges that had been game-changers for affordable magnetic phono pick-ups in the 1950s.

In this, its 50th year of company operations, Phase Technology announced and demonstrated a new type of loudspeaker system. The series, named dARTS for Digital Audio Reference Theater System, is obviously aimed at the custom-install, home-theater market, but the components and concepts are applicable to music reproduction in any number of channels. As described by PT's director of sales and marketing, Tony Weber, the dARTS system is (1) modular and (2) actively powered and equalized by DSP, incorporating Audyssey's MultiEQ XT for digital room correction.

My, how we've grown! The experience that convinced me of the inevitability of streaming was in 2010 with the tiny, tidy Logitech Squeezebox Touch that, despite being discontinued and disowned by its manufacturer, still has a cult-like following. Since then, we have seen an explosion of devices for file playback from local or nonlocal storage and web streams.

Pioneer S-1EX loudspeaker

Floor Loudspeaker Reviews

One of the highlights of such annual events as the Consumer Electronics and Primedia Home Entertainment shows has been the demonstrations of loudspeakers from TAD, the professional division of Pioneer Electronics. Designer Andrew Jones is always generous in using recordings brought by visitors, and enthusiastic in explaining the technology behind these beautiful behemoths. Among these speakers' unique features are a beryllium dome tweeter mounted concentrically inside a beryllium midrange cone, and a cabinet built of stacked, carved horizontal sections, for incredible rigidity without using exotic materials or excessive mass. The concentric upper-range driver is a reminder that, some time back, Jones worked for KEF, where the coaxial UniQ driver was developed, but the materials and details of the TAD drivers are all new. While the TAD Model 1s are always good for musical and audiophile thrills, their price is in the upper five figures, which put them out of serious purchase consideration.

Pioneer's Flagship Two-Chassis Receiver

CEDIA 2007

Kalman Rubinson | Sep 07, 2007 | 1 comments

Pioneer showed a number of interesting new products in two-channel electronics and speakers. but pride of place was ceded to their new flagship A/V receiver, the SC-09TX. This is almost, but not quite, a pair of separates with the 10-channel, ICE-powered class-D amp confined to a chassis separated from the rest of the digital and line-level electronics. The main 7 channels are rated at 200W, operated simultaneously. I thought it notable that the amplifier chassis is configured to be under the main chassis and that indicates that we’ve reached a point where the efficiency of class-D amps allows the power-hungry DSP and video processing to breathe out the top. Fans help, too. Every conceivable input and output is provided including 6 HDMI inputs and two HDMI outputs, accommodations for XM, Sirius, and iPod input, and a talented EtherNet link. I show you the back panel to impress you with the connectivity and the distinct chassis for the power amp. The front panel sports a 4" LCD for control and video previewing.

PMC fact.8 signature loudspeaker

Back in the Dark Ages, loudspeaker design was commonly based on semi-enlightened experimentation, with new enclosure configurations appearing almost monthly in professional and consumer journals. One of those, published in Wireless World in October of 1965, was A.R. Bailey's transmission line, a long, selectively resistive, folded-and-sometimes-tapered tube that loaded the back of the (woofer) driver for low-bass reinforcement.

PMC IB-1S loudspeaker

I have a soft spot in my heart (some say my head) for transmission-line designs. I remember being entranced by the authoritative but effortless bass of John Wright's IMF and TDL Monitors, and I have been inspired to experiment by building my own lines in various sizes. Then, as demonstrated by Bryston's Jim Tanner at the 1997 WCES and at HI-FI '97, PMC's IB-1S loudspeakers threw an enormously deep soundstage. (I have a soft spot for that as well.)

Kevin Deal was so proud of his new DiaLogue Premium HP power amplifier ($3899 stereo or monoblock) that he insisted on showing off its underside so that we can all appreciate the quality of the components and the fastidious wiring.

Primare A35.8 8-channel power amplifier

Solid State Power Amp Reviews

Back in 1999, while reviewing the Wazoo integrated amplifier from Bow Technologies, I learned that its designer and company founder, Bo Christensen, had previously founded another audio company. That's how I discovered Primare. Over the years, various products from Primare have appeared at audio shows but never grabbed my attention. In a recent EISA press presentation, however, Primare showcased an eight-channel amplifier that did, given my interest in multichannel audio. I was glad to be able to attend.

Pro-Ject's little audio boxes

CES 2014

Kalman Rubinson | Jan 14, 2014 | 1 comments

Pro-Ject easily wins the competition for who can offer the greatest number and variety of little audio boxes. With their range of turntables distributed around the room, they had an entire large wall covered with their devices, DACs, CD players, preamps, mono- and stereo-amps, switches, power supplies, tuners, and phono stages. They also had boxes with combinations and permutations of these functions and most of them came in more than one of their various ranges, E, S, DS, DS+ and RS, in order of feature set and price. I was most intrigued by their Stream Box DS music streamers, all of which handle up to 24/192 via WiFi, LAN and USB and offer Internet radio via vTuner as well as Spotify and other streaming sources. A 3.5" TFT color display shows text and album art. As you go up the line, you can add iOS and Android control, ALAC support, analog and digital inputs or, even, built in power amps. Prices start at under $1000.
