The surgery at the back of the basement became my wife's office, and I took over what used to be the dentist's lab, complete with gas fittings for Bunsen burners and workbenches for my audio test gear. ![]() We reintegrated the basement with the rest of the house and, before moving in, knocked together what used to be the patients' waiting room and a storage room to create my listening room. However, when we relocated the editorial offices to Manhattan in June 2000, New York real-estate prices made that approach impracticable.įortunately, the Brooklyn house my wife and I had bought had a large basement that used to be a dentist's surgery. When the magazine was based in Santa Fe, New Mexico, both our test lab and the large room I used for speaker testing were in the office building we shared with Stereophile Guide to Home Theater (now footnote 2). Which reminds me that it has been many years since I listed the test equipment I use to generate the measurements sidebars that accompany Stereophile's reviews. This is also a problem I'm facing with the DRA Labs MLSSA software-hardware combination I use for my speaker tests. ![]() But even with the help of eBay, keeping and maintaining a stable of older PCs with the necessary AT-bus slots for the interface card is not getting any easier. As clunky as the System One's DOS control program was, it was as comfortable as a beloved but frayed and faded pair of Levi 501s, and I could get it to do all sorts of tricks without having to think overmuch. This is for consistency's sake, and to enable me to get familiar not only with the new system, but also with the Windows XP–based interface for both control of the tests and graphing the results. While the SYS2722 is capable of very much more than the System One, at present I am echoing the set of test procedures I have developed over the years as I shift the test regime to the new platform. (They did on the tests where the SYS2722's improved resolution was not a factor.) In fact, with the equipment I tested using the SYS2722, I performed duplicate sets of measurements using both the System One and the Miller Audio Research QC Suite in order to get a handle on how close the three systems agreed. ![]() The reviews you can read in this issue include the first measurements I have performed with this impressive piece of gear, though there are still a number of graphs I produced using our System One. As I wrote in this space last month, test-equipment manufacturer Audio Precision has loaned Stereophile a sample of their top-of-the-line SYS2722 system (footnote 1), which has both significantly greater resolution and greater bandwidth than the Audio Precision System One Dual Domain we have been using since 1989.
