Last late Winter… or early, early pre-Spring, depending on how you prefer your "pretty much the same with some slight differences, though not really all that much" seasons here is SoCal, I found myself staring at John Young's Acoustic Imagery Atsah (Htpex NCore 1200 Class D power amplifiers, $9995/ pair based on the Hypex NC1200...

Audio Ramblings – Verastarr Grand Illusion AC Power Cords


Verastarr Grand Illusion AC power cords ($2500 in 6 foot length) use high purity copper metal foils and produce a musical presentation that is big, bold, and robust. Not to be clichéd here, but being a copper-based cable, and using lots of copper to address skin effect with its four 2-inch wide foils, music with... Read More »


Your Final System (YFS) PS-12m Mac Mini Power Supply/Internal Power Filter Mod


If you're an audiophile, you realize at some point that digital spinning discs won't be around forever. Although that realization hit me several years ago, it took quite a while before I really decided to get serious about a digital source based on a computer. I'd heard several computer-based rigs at shows, and what I... Read More »

Dynamic Design Heritage Challenger AE15 Digital Power Cord


Power cords are a specialty within the category of audiophile connectivity that is mighty important. Those supplied with the gear, regardless of price, are merely included to allow the equipment to meet specifications and light the LEDs.

The eXemplar System


A Little Background It's safe to say that mentioning John Tucker's eXemplar audio to an audiophile is likely to get one of three reactions. The most likely reaction is a blank stare accompanied by the questions "Who?" and "What?" There's a smaller group who hears the name and asks, "That guy with the big horns?"... Read More »

The Garrard Project 2015: From Simple to Spectacular!


There's just something musically magical about the performance of idler-wheel Garrard transcription turntables that keeps me fascinated with them. Certainly the vintage Garrard 301 represents a beloved milestone of turntable design that remains enduringly popular with hi-fi enthusiasts to the present day, and who, like the 1956 Garrard advertisement below suggests, have concluded that Garrard...

Audio Ramblings - Skogrand SC Beethoven Speaker Cables


So here we have the Beethoven loudspeaker cables from Skogrand that at $22K are something I tend to never review. Actually make that never ever ever review. Just not at a price point that I am comfortable with, or one that I would ever consider as a purchase option—and yes, even with an industry accommodation.... Read More »

Impressions: The Oppo Digital HA-1 Headphone Amplifier/DSD DAC and PM-1 Headphones, Double Helix Cable Complement3 Headphone Cables, PranaWire Photon USB Cable, and Kubala-Sosna Elation! Cables


I might as well come out and admit it. I've been a big fan of Oppo Digital and their product lines since I first tried them out, years ago now. I think that I've been through almost every one of their players from way back when. That would include the DV-983 DVD/audio player…don't think that... Read More »

The Vintage McIntosh Experience: A Musical Ride With The MX110Z Tuner/Preamplifier and the MC30, MC225, and MC240 Amplifiers


I've really had a lot of fun listening to vintage McIntosh vacuum tube audio electronics in my hi-fi system over the last year.

The Voice of the Heretic – Is Red Book CD Hi-Resolution Audio?


With my forays of the last few years into computer-based audio, I've really come to appreciate the lowly compact disc. Even though the prevailing logic would tell me that they're on the way out—very much like LPs were on the way out when the CD appeared in 1981, right? I think just about everyone has... Read More »
