Ortofon MC X20 Moving Coil Phono Cartridge


Hard to believe, but the first time I reviewed an Ortofon cartridge for PF was way back in the fall of 2008 (read it HERE). The company had just introduced their then-new 2M series of affordable moving magnets that were notably different looking and sounding than other price-competitive cartridges, the basic architectures and styling of...

XACT S1 EVO Music Server


The formula is simple. If you voice the component in a way that resonates with enthusiasts, odds are it's going to take off. What's left is securing media coverage to sustain consumer enthusiasm. I was not surprised to see the S1 Music Server from XACT take that route. Once you've heard its big tone—ample body,... Read More »

What manner of arcane sorcery does David Salz of Wireworld Cable Technology practice behind closed doors in the depths of his cryptic labyrinth? Are mystic spells being chanted, obscure rituals observed, and talismans of power wielded in the creation of magical and wonderful wires? Or perhaps I've simply spent too many hours this weekend binge-watching... Read More »

RAY Tubes Reserve EL34 and Select 12AU7 Vacuum Tubes: Elevating My PrimaLuna EVO 300 Integrated Amplifier's Performance to Unforeseen Heights!


Growing up in late-sixties north Georgia, music first really grabbed my attention around my tenth birthday.

I spend a fair amount of time on social media, especially Instagram; it's a great space to post meaningless snippets of existential nonsense, and is less overtly cluttered by the intense political rants that have bogged down Facebook. Not that I'm apolitical—you don't want to get me started about the current state of affairs here... Read More »


Atma-Sphere Class D Amplifiers


Preparing for this review I asked Ralph Karsten, principal at Atma-Sphere, if he planned to make a Class D preamplifier. He responded "There's not much point in a Class D preamp since you don't get the same advantages that you do in a power amp." The obvious question becomes: what are the advantages of a...

Small Green Computer sonicTransporter i7 CDR (Gen 3) and Sonore opticalRendu Deluxe


It was back in 2015 that I decided to get into a digital audio source that was not based on either a CD Player or a Transport/DAC combo. I'm really having a hard time wrapping my head around just how long ago this was. In the 2015 May/June issue of PF—now in the archives—I wrote... Read More »


Vincent Audio SV-500MK Integrated Amplifier
