Sometimes we come to the reality that a certain product in our system is not the be all and end all we thought it was. Take for instance the "built-in DAC". It is a great idea till that fast paced technology renders that chip obsolete. I have often thought that what I have my system plugged into was... Read More »

Power conditioning products, like the Spiritual Audio VX-12 under review here, are still one of the most esoteric high end audio products produced today. I say that because they contain some very intricate designs that are usually so proprietary, some of them are sealed from anyone being able to peek inside. I know that can be... Read More »

There's every probability you already have an opinion about audiophile tweaks and the folks who review them. Sometimes it seems like half the double-blindsters on the internet remain fixated on the original AudioPrism StopLight CD marker pen, so discussing any device from that company entails a certain incendiary risk-especially as Positive Feedback now features a...

I may have said this before, but I'll say it again… all of these amazing cables you have in your system (as beautifully constructed as they are) will not amount to much if you have garbage power coming into your room. This probably goes for 99% of you reading this where you don't have the... Read More »

I think we can all agree that, generally speaking, the thought of experiencing a new power supply or conditioning product is not quite as exciting as fresh new speakers and amplifiers. I mean, who really wants to spend all that money on electrical cords and outlets? Still, I have experienced several power cords and power... Read More »

One can wonder why so many people at certain age start using expression "I remember that..." more and more often. I can not not remember that several years ago whenever I came across such expression in a text it usually ignited at least some level of aversion towards obviously "advanced" age of its author. Why... Read More »

Several months ago I wrote about Blue Circle's FX-2 X0e PLC and was impressed enough to purchase my review loaner. When visiting Blue Circle's Gilbert Yeung at last year's TAVES he suggested I try his new balanced power based TPX120. The TPX120 is a plug-in balanced power module that offers 120W of filtered and balanced... Read More »

As many of you know—and as the title reference to "The Acoustic Revive Chronicles" suggests—over the years I've written quite a lot about the innovative Acoustic Revive audio accessories designed by the brilliant Mr. Ken Ishiguro in Isesaki, Japan. In fact, I've spent more time writing about Mr. Ken's Acoustic Revive accessories than I have... Read More »

The First Blueport "Audio Transcendence" Award (With a response by Marshall Nack) What does it mean that the onset of Global Warming coincides with the arrival of a theoretical Golden Age of audiophile possibilities? I'll think about that awhile as the emergence of DSD (direct stream digital), after a quarter-century languishing in audio twilight with... Read More »

Audience has made a name for itself over the years by producing very fine interconnect cables, phono cables, speakers, and power chords well as the Teflon Aura-TO (Teflon) capacitors. The star of their product line, which has always received rave reviews, has been their power line conditioners.(1) The Audience power line conditioners are not inexpensive.... Read More »

Blue Circle's Gilbert Yeung is one of high end audio's more colorful and unconventional characters. I can't think of another audio designer who would offer an amplifier with 2,000,000uF of power supply filtering and a 288 opamp output stage or a line of ridiculously inexpensive high performance products enclosed in ABS pipes. The latter is... Read More »

"What's this?" I expected a power distributor, but this shipping box is large and heavy enough to mandate a luggage cart for haulage. Then I recalled Brian Ackerman, the importer of HB PowerSlave products, telling me that first look would be a shocker.  The HB PowerSlave Acrylic is one of those massively over-built products that...
