In this issue: We have two reports on the AXPONA 2025 audio show, from myself and Rudy Radelic. Octave Records gets funky with Protostar by the Black Hole Boogie Band. I get a rare opportunity to hear the legendary Hill Plasmatronics loudspeakers. Paul McGowan offers advice on optimizing the listening room in The Audiophile’s Guide book series. Wayne Robins sees a new generation discovering the Beatles and “Strawberry Fields Forever.” Ray Chelstowski talks with legendary rocker Don Felder.
B. Jan Montana sees that when Zeus is dead, Chaos reigns. Peter Xeni has a look at 50 years of the Melbourne Audio Club, one of the world’s oldest audio societies. Our colleagues at FIDELITY magazine visit turntable and cartridge manufacturer Clearaudio, and a PMA Magazine writer…quits audio? My series on playing in a rock band goes to some extremes outdoors. PS Audio introduces their new top-of-the-line PMG Signature Series. Ken Kessler won’t quit in his pursuit of vintage Revox reel-to-reel decks. We round out the issue with channel surfing, a monolithic loudspeaker, and mind games.
