Quicky: Block Audio's New C-Lock Power Connection Guard

Linear Tube Audio's Microzotl Preamplifier and ZOTL40 Reference Amplifier


Prologue: A Berning Desire Many years ago, I purchased a boxy little bespoke headphone amp for my Sennheiser HD600's called a MicroZOTL. Built by a mysterious mid-Atlantic, not-so-mad audio scientist by the name of David Berning, the MicroZOTL was a mighty tiny wonder. I loved it so much I had physicist / audio manufacturer Berning...

Audiophile Decorating: Making the Listening Room Sing


Exordium I've been a lover of music and audio for as long as I can remember. I didn't really recognize myself as an "audiophile;" but from my first 45 rpm box player in '63, to an all-in-one Sears stereo, followed by a succession of Pioneers, Harman-Kardons, Yamahas, and Kenwoods; I loved gear even then. I... Read More »
