Harman announced and demonstrated a new audio processing format called QuantumLogic. Extremely complex, what it offers, on both the recording and playback end, is the ability to manipulate the signal in unprecedented ways. For example, it can isolate a solo singer, or just the orchestra, or even just the ambience, and process and move it around in the sound field in almost any way the user (or the recording engineer) desires. The extraction process is nearly total. The process provides extreme flexibility for enhancing (or, it must be said, compromising) the sound, again either on recording or playback. You'll be hearing a lot more about it both here and elsewhere in the future.

The first product to include QuantumLogic will be Lexicon's new MP-20 Media Processor. It has also been implemented in a Ferrari which was on display on the show floor, but that's hardly a mass market item (nor is the five-figure processor!).

Here's a cutaway look at the insides of the Polk flagship LSiM 707. You can see why the release of the new LSiM lineup was much delayed. The cabinets are very complex to build.

Kaleidescape's CD/DVD/Blu-ray server gets around the copy protection issue with Blu-rays by having the user load his or her Blu-rays into this carousel-like unit--the Vault. The discs are then loaded onto hard drive servers and played from there. But they will only play from the server if the unit confirms that they are still in the Vault. If not, the server will no longer play the disc file. That's not a limitation with CDs or DVDs, which can also be loaded into the Vault, but can be removed (but still play) after copying onto the hard drives. The Vault holds over 300 discs, but the number of Blu-rays you can load will depend on how big a server you purchase. No word on whether the pretty blue light is standard or just a show special.

I reviewed the Aragon 8008 amplifier for Stereophile back in the mid-'90s and loved it. I often wished I'd bought it, in fact, as it was a near perfect match for my Energy Veritas v2.8 speakers. When Mondial (the original source company) folded, the Aragon line (and the lower end but also well-regarded Acurus products) was acquired by Klipsch. That company never really supported either of these lines. The rights were recently acquired by a company called Indy Audio Labs, which has just re-launched the 2-, 5-, and 7-channel Acurus amplifiers (200w/ch intro 8 ohms, all).

Later this year Indy plans to re-introduce the Aragon 8008 mkIII, 2-channels at 200W/ch (8 ohms) at $4000 and the Iridium, a 400W (8 ohms) differential monoblock, successor to the Aragon Palladium, at $4000 each. Apart from some added control and status features, the amps are said to be nearly identical in design to the earlier versions, though to my recollection the original Palladium was lower powered (but biased heavily toward Class A). And, of course, those 1990s models were considerably cheaper. Time marches on.
