One reason the NAD M5—indeed, all of the Master Series components—sound so good, Mark Stone says, is the gigando special NAD class-A gain modules, which "offer tremendous dynamic headroom and nearly immeasurable distortion." JA is working on a review of the M3 integrated amplifier, which also uses these modules.

Lenbrook Technologies' Mark Stone pops with pride over NAD's Master Series $1799 M5 SACD/CD Player, which employs separate signal paths for CD and SACD. The player's CD resolution is 24-bit, 192kHz. Since it's aimed at audio systems rather than HT applications, the M5 includes comprehensive bass management for multichannel SACDs and front-panel–accessible preset 5.1 speaker configurations.

The amiable team of industry veterans David Solomon (left) and Jim Spainhour (right) make up Signal Path, who distributes Musical Fidelity products in the US. They are seen here with MF’s new “audio Swiss Army knife,” the kW250, which includes a CD player, an FM tuner, a preamp with an MM phono stage, and a 250Wpc power amplifier for its $9000 price. A digital input on the back takes the feed from your music server and yes, there is a jack for your iPod on the front. "An ‘exit-level’ component," is how Jim describes it, "for the middle-aged music lover who wants system simplicity without sacrificing sound quality."

It was only a couple of CEDIAs ago that Paradigm introduced its Signature series of high-performance speakers, and I was very impressed by the stand-mounted Signature S2 when I reviewed it for <I>Stereophile</I> in July 2005 (see http://www.stereophile.com/standloudspeakers/705paradigm/). But the Canadian company’s big news of the Show was that they have redesigned, not just the Signature series but their entire line! The new models use beryllium-dome tweeters and midrange units with aluminum cones treated with cobalt to add stiffness. The looks of the Signature series are still to die for, however.

File this under <I>Only at CEDIA</I>: Themeaddicts, Inc. is offering a Magic Message Mirror (also available as a talking pirate skull). The MMM looks like an ordinary mirror, but is integrated with your whole home automation system. It can update you on any changes within the system's ability to monitor.

PSB's Paul Barton is juiced about in-walls. One problem that in-room loudspeakers have is that they have a change-over point from 2-&#960; to 4-&#960; operation. Well, with in-walls, it's all 2-&#960;."

It's official. I am a nerd! I couldn't resist snapping the interior of Theta's amplifier, which takes an audio input as PCM digital and transforms it into PWM digital without ever changing it back to analog until the music arrives at the speaker terminals.

Neil Sinclair gave me a tour of Theta’s new multi-channel amp, which keeps the signal exclusively in the digital domain from the S/PDIF inputs to the PWM output stage, the latter said to operate at the super-high frequency of 1MHz. Designed by veteran amp engineer Dave Reich, what is in effect a powerDAC&mdash;that’s what it says on the output-stage printed circuit boards&mdash;will find its way, I hope, into some two-channel products in due course.
