Synergistic Research HFT and FEQ


At the last Diana Krall live concert I attended, I happen to be seated next to an elderly woman who took great pleasure in singing, with all abandon, along with Ms. Krall for most of the concert. What made it worse was that she seemed to be quite tone deaf and sang totally out of... Read More »


The Audioengine A5+ Wireless Loudspeakers


"Get your station at the touch of a finger!" shouts the vintage ad for General Electric radios. "Touch tuning - Does away with tedious dialing!"  Now, that's an innovation one can hang a fine felt Cavanaugh fedora on. True, the pushbutton worked better in a VW bug than in the home, but you get the... Read More »

The Hana EL Moving Coil Cartridge: Exceptional Performance at an Agreeable Price Point


Late last year, I had a tremendous review opportunity that focused on ProJect's The Classic turntable; unbeknownst to me, the review unit arrived as the heavily upgraded Superpack SB edition. Which, along with electronic speed control and other really nice goodies thrown in, also came with a Sumiko Blue Point No. 2 cartridge attached to... Read More »


STEALTH Audio Helios Phono Cable - Analog Dreams of Noise-Free Vinyl


Saturday mornings I'm at the Greenmarket early and later I make my way over to Academy Records, my favorite music retailer. While perusing the bins recently, I stumbled upon Jazz Ballets from Broadway, an early stereo LP from 1958 (Warner Bros BS 1240). The title won't ring a bell for many people, but it was...

When you order the smoked eel at the bar of this London seafood... Read More »


The Gingko Acoustic Resonance Clarifier™ (ARCH)


As I began listening to the Gingko ARCHs the many audio tweaks I've tried over the years ran through my mind. The more I thought about it virtually every system I've heard, no matter price or size, included some sort of accessory I would—at least loosely—label as a tweak, an accessory that can improve the...

JCAT USB Isolator - Enhancing USB Audio Playback to the Nth Degree


I've been using JPLAY as my go-to computer-based music player/streamer for the last couple of years—it's without a doubt the very best bang-for-your-buck improvement for use with any PC music playback system.

Shunyata Research Sigma Phono Cable


I think of Shunyata Research as an investigative research center for signal and power transmission. And I suspect its principal scientist, Caelin Gabriel, has a lot of fun digging into how electricity works, down to the quantum level. After all, Gabriel spent his early career with the NSA, designing military systems to acquire extremely low-level... Read More »

Tellurium Q Interconnects and Speaker Cables


I wonder if Geoff Merrigan, the owner and designer of the British company TELLURIUM Q is having nightmares? The question seems to me to be all the more justified, since both him and his company have roots in the pro world, that is, one set on functionality and utilitarianism and reluctant to any experiments.
