Editor's Note: Published in 1998, this was the final review written by Stereophile's founder, the late J. Gordon Holt in the 37 years he was associated with the magazine. In it he expounds on his passion for experiencing recorded music in surround sound. Our continuing focus on two-channel products and recordings was one of the reasons Gordon eventually resigned, in August 1999.—John Atkinson

Because I'm suspicious of just twiddling knobs to make the sound "nice," I didn't rely solely on my ears when I used the Z-Systems rdp-1 that I review elsewhere in this issue for speaker and room contouring. Instead, I used the ETF speaker/room-analysis software from Acoustisofthttp://www.acoustisoft.com">Acoustisoft; to help me manipulate the equalizer properly. This program can measure the first-arrival, on-axis speaker response, as well as the room response with its early and late reflections and its resonances.

In a sidebar to his">http://www.stereophile.com//loudspeakerreviews/542/">his review of the B&W DM302 speakers in the October 1997 issue (Vol.20 No.10), Wes Phillips mentioned a handy tool he uses for speaker setup—a laser level. The one Wes used was originally intended for construction work, not tweaking one's speaker placement, but now there's one available specifically for that purpose: The 770 SA-S Laser Sound Alignment System by Checkpoint Laser Tools.

Introduced nearly eight years ago as the first recordable digital format for consumers, DAT both failed to appeal to its target market and was blocked from formally entering the USA for four years by the RIAA, who feared for the copyright of its members' recordings. However, the DAT medium was enthusiastically snapped up by professionals and semiprofessionals, who found its combination of reliability, CD-compatible signal format, and editing ease ideal for mastering. Sony currently offers a small range of consumer models, from the diminutive Walkman-sized TCD-D-7 DATMan to four-head cassette-deck–sized machines for the so-called "prosumer": amateur recordists who make pin money taping local concerts. The DTC-2000ES is Sony's latest entry (footnote 1).

"Crossovers? We don't need no stinkin' crossovers!" Most Stereophile readers probably feel this way when it comes to third-party electronic crossovers. In this day of proprietary "soup-to-nuts" speaker systems, nearly all manufacturers supply complete systems. Nevertheless, some brave (or foolish) souls still choose to sail in uncharted crossover waters. Most do so because they're insanely in love with their current speakers, and have an irrational desire for that last bottom octave. Others have "orphaned" speakers that are not readily upgradeable to the next level of performance. I fall into the second category.

Although most audio perfectionists look down with scorn on equalizers, there are times when the benefits of such devices can outweigh their disadvantages. I discussed the pros and cons in my review of the Accuphase G-18 in Vol.11 No.4, but a brief recap here won't be amiss.

Dear Steve:

I cannot question the general value of Tiptoes in many specific applications. There are a great many areas where I, many other audiophiles, and a number of leading manufacturers have found that Tiptoes can improve any audio system in which the components are subject to. mechanical or acoustic vibration from speaker sound—that is, virtually any audio system.
