Why does the cable connecting the Audio Design Associates MPS-502 amp to its external power supply resemble a thick piece of plumbing -- like the pipe under your bathroom sink? Well, it has to carry 100 amps of current, so it can provide five channels with 450 watts each. Introduced in 1992, this was the amplifier on which THX based its amp spec. Throw in the PF-2502 to bring the system up to seven channels. In the present day, ADA is shipping two pre-pros, the Suite 7.1 ($5500) and Cinema Rhapsody Mach IV. You can buy the latter for $4100 but you'd be better off paying $7500 for the version with Trinnov auto setup and room correction. Trinnov will also be built into a separate equalizer product, the TEQ-1. (We are looking forward to trying Trinnov in the long-awaited Sherwood R-972 receiver.)
Two years ago, PSB introduced the top-line Synchrony line. A year ago an almost equally high-end line was added, the Imagine. With the revised version of the Image, PSB's number three falls into place. There are two towers and three monitors and -- tower-averse as we are -- we think matched sets of any of the latter would make a fine basis for a system. These two-way stand-mounts include the B6 (6.5-inch woofer, $499/pair), B5 (5.25-inch, $399/pair), and B4 (four-inch, $299/pair). We've heard the B6 and B4 and they're superb, with more bass than you'd expect. This is one of the few speaker brands whose founder, Paul Barton, spends significant amounts of time in China QC-ing the product.
Proficient is a new brand name in receivers and we look forward trying one of its two surround models. The M60 has 80 watts times seven, four HDMI ins, and SmartEQ for $600. Step up to the M80 and you get all that plus 130 watts times seven, Faroudja DCDi video processing, and XM satellite radio compatibility for $1250. Proficient also showed an eight-channel power amp, the M8, with 35 watts per channel, for $1100.
A notable speaker brand makes common cause with a distinguished acoustics consultant to create home theater systems worthy of the description high end. The CinemaPlus systems will combine design, engineering, and support from PMI -- Anthony Grimani's company -- with acoustic treatments from MSR and speakers from Triad. The curved baffle wall shown in the picture is part of the package. It is modular and scalable. Systems will start at $46,550 for a small room (2000-2999 cubic feet), rising to $88,650 for a medium-sized room ($3000-5999 cubic feet), and topping off at $105,350 for a large room (6000-12,000 cubic feet).

Yup, they're actually calling it the SCS, and yup, that does stand for "suitcase sub." Companies like this are like manna to journalists. The narrow vertical sub hugs the wall and packs in dual 5x7.5-inch drivers, which yield an active cone area of 12 inches, powered by 300 watts. Probable price $4000, shipping in 30 days. We didn't let it distract us from the excellence of Wisdom's Sage Series line source planar speakers, the L100i and C150i, which speak like oracles through a woven screen.
It is large, as many of us discovered when we walked through it to get to the Omni for preshow events. Atlanta itself is large, spread out, surprisingly hilly, and not walkable. However, I am grateful to finally attend a CEDIA Expo on the east coast. Perhaps Atlanta will grow on me during the next two CEDIAs, which will return here.
Phil Clements, father of H-PAS technology, explains its use in a bar speaker. While Atlantic is studying this prospect, the product shown is pre-H-PAS. It is a seven-channel configuration with three tweeters and two 4x6-inch woofers in the front and two on the sides for surrounds. Channels are shared among the drivers with a triple voice coil structure. A "180-degree feel" is promised.The bar is the FS-7.0. With eight-inch sub, it is the SB-8800 system. Shipping in September for $800 (for the bar) and $300 (for the sub).
This mockup gives an indication of what the production model may look like. However, Atlantic is studying the use of 5.25-inch woofers in lieu of the 4.5-inchers shown here. It may ship in December give or take a month. Atlantic also plans to license the technology to a half-dozen other manufacturers including at least one "super high end" player and various "upper mid-fi" brands, according to Tribeman.
As we previously reported, the H-PAS speaker technology making its debut at Atlantic Technology's off-site exhibit has been one of the most eagerly awaited events of the show. Simply put, this bass-building speaker technology works -- with tympani, bass clarinet, and of course pipe organ. While the midrange was not perfectly balanced, and we were informed that voicing will be tweaked, it was clear that Atlantic is correct in claiming that deep bass episodes don't starve the mids and highs or collapse the soundstage. What makes it work is what Tribeman calls a cascading of well-known speaker design elements such as bass reflex, inverted horn, acoustic suspension, and transmission line. In other words, "it's all in the plumbing" -- the drivers and crossover are nothing special. Credit is due to the inventor, Phil Clements of Solus/Clements. The prototype shown uses a pair of 4.5-inch woofers and is said to be flat down to 30Hz.
