For its PerfectWave DirectStream D/A processor, featured on our September issue's cover, PS Audio took a different approach. Rather than using the usual off-the-shelf parts, designer Ted Smith used Field-Programmable Gate Array chips (FPGAs) to process DSD data without compromising the integrity of the music. Art Dudley takes the new DAC out for a test drive and returned impressed by what he heard. This issue also sees the indefatigable Mr. D. enthusing about 47 Laboratory's Model 4730 Midnight Blue FM tuner—which uses a dial! A dial!
The September Stereophile kicks off with Jason Serinus comparing concert halls, while Michael Lavorgna has seen the future of streaming, with lossless CD-quality music available from Qobuz; Michael Fremer auditions cost-no-object phono preamps; Sam Tellig raves about Spendor's new D7 tower speaker; and affordable high-performance loudspeakers from KEF, Revel, and Triangle get the in-depth review treatment. Add Robert Baird's feature article on jazz great Louis Armstrong and you have one heck of a great read!
