Although the CD was successfully released into the music industry gene pool 20 years ago, several companies are still tinkering with its DNA in order to assist record labels in restricting how consumers use their discs.

"At a mere $65,000," Martin Colloms states, the <A HREF="http://www.stereophile.com//loudspeakerreviews/909/">Wilson Audio Specialties X-1/Grand SLAMM loudspeaker system</A> "could be regarded as something of a bargain." MC then goes on to explain himself in great detail. The "longest, most thorough speaker review we have ever published!" notes John Atkinson, wiping the sweat from his brow.

Late summer isn't typically a time when new audio products appear, but on August 29 we received two noteworthy announcements.

The Recording Industry Association of America (RIAA) may spend the rest of its associated life in litigation&mdash;as either as the initiator or the recipient of actions intended to determine who can use its products, under which circumstances they can do so, and how much they should pay, assuming they are allowed to use them.

At the end of July, UK-based TAG McLaren Audio, which had been experiencing difficult trading conditions and was reducing its workforce, issued a rather pessimistic <A HREF=&rdquo; http://www.stereophile.com/shownews.cgi?1701&rdquo;>announcement</A&gt;. The core of the announcement concerned the firm's commencement of "a full strategic review of its participation in the audio market."

It's been a rough year for the music industry&mdash;and possibly an even rougher one for audiophile labels. The Dorian Group, however, seems to be thriving. Parent company to Dorian Recordings, the Dorian Group announced last week its acquisition of Reference Recordings. During its 25 years in business, RR has consistently garnered praise from audiophiles for the sound quality of its recordings, and has scored eight Grammy nominations and two Grammy awards.

DVD-Audio is getting a boost from several directions.

To combat lackluster CD sales and online file trading, some record labels have been adding bonus DVDs to new releases to get consumers to buy them instead of downloading the data. DVD-Audio proponents, in an attempt to counter Super Audio Compact Disc's single-disc hybrid SACD/CD strategy, have been trying to figure out how to combine CD functionality and DVD-A onto one disc.

More from the August issue: Larry Greenhill updates his system with the <A HREF="http://www.stereophile.com//amplificationreviews/905/">Mark Levinson No.436 monoblock power amplifier</A>. LG says, "I was concerned when [Mark Levinson] discontinued its entire 300 series of dual-mono amplifiers, but the company reassured me that they had a suitable replacement in the No. 436." Greenhill decides for himself.
