Playback Designs Integrated Single Chassis Sonic Masterpiece: The IPS-3


What? My first "hi fi" stereo box, in 1957, was an elegantly constructed Magnavox LP changer with a built-in amp-preamp feeding two inch mono speakers.

Frank Sinatra's Hi-Fi, circa 1947


Well, lawdy Miss Clawdy! John Marks' latest republication from The Tannhauser Gate is compact, but delicious. A shout from the past, really, right after World War II, but before Bing Crosby's Ampex Corporation with its pilfered Nazi technology that we today call "tape recorders" hit the scene. 78s everywhere, of course; no LPs to be seen. A... Read More »

So, two things on my mind here… the Aurender A10 and how wonderfully musical it is, and the WireWorld Starlight Cat8 Ethernet cables… and how they work so well together.
