Is your music system hypo allergenic? 10

Posted 7 years ago

Just heading out the door, went to fire up the dishwasher and the marketing pitch on the soap caught my eye. “Now, Hypo Allergenic!” What the hell does that mean? It was the main selling feature of the dishwashing soap and for years I have taken it for granted. In fact, I might choose one […]

I only read the last few paragraphs 10

Posted 7 years ago

Magazine reviewers work hard at writing a review – many thousands of words written to make sure you understand a product and really get what the reviewer feels about that product. It’s a long time tradition of a thorough piece of work. Yet I only read the first few paragraphs of a review and then […]

Why a dedicated computer isn't a dedicated server 8

Posted 7 years ago

A lot of folks out there are taking an older unused computer or even a new MAC Mini and dedicating it to serving their music. This is a good idea relative to using a shared computer to do the same – but dedicating a computer to this task isn’t the same as a purpose build […]

It's only the music I am interested in 12

Posted 7 years ago

Really? I hear that a lot and I am sure it’s true for some of us. But my sense is most of us like the gear, the kit, just as much as we like the music. When I attend a consumer audio show I see endless numbers of people wandering from room to room looking […]

Dynamics 10

Posted 7 years ago

Not to be on a nostalgia kick here but yesterday’s post about Direct to Disc recordings got a few of you to ask me why a Direct to Disc was so much more dynamic than a standard recording and the answer is simple: one less layer and vinyl has more dynamic range than does tape. […]

Direct to disc 3

Posted 7 years ago

In yesterday’s post we mentioned a Sheffield Direct To Disc recording and several readers asked me just what that was. It was the most direct method of recording possible before the advent of digital and interestingly enough it was a throwback to the original recording technique. Perhaps a bit of history is in order. When […]

Fewer choices 5

Posted 7 years ago

Back in the 1970’s when high-end audio was just blossoming into a real force there were many more dramatic choices of tailoring your system the way you wanted it to sound. For example, I remember the first time I was introduced to a Decca phono cartridge and compared it to the Stanton III cartridge – […]

Here we go again 7

Posted 7 years ago

I finished reading yet another article by a self proclaimed expert about why 192kHz 24 bit doesn’t make any difference over standard CD’s and the folks who are promoting these standards are simply “hoodwinking” you into believing they do. What’s instructive about this article is the author, Monty, is extremely knowledgeable about a lot of […]

You should worry about your chair 17

Posted 7 years ago

Just when you thought it was safe to relax in your listening room and enjoy the music let me make you aware of the damage your chair might be inflicting on the music. Yes, the chair. One of the items of furniture in the room you should be careful with is the chair and its […]

Amanda Mc Boom Boom again? 32

Posted 7 years ago

After reading yesterday’s post about the art of the demo, my friend Jim McCullough of Cello reminded me that the third side of the demo coin was the endless playing of the same Audiophile pap to demo equipment at shows. I can remember thinking if I hear Amanda McBroom one more time I am going […]

Integrateds 23

Posted 7 years ago

In yesterday’s post about the preamp conundrummany of you correctly pointed out that what I was referring to is called an integratedamplifier but perhaps missed my point. The day of the preamp as a separate is long over and while there are multiple ways to address the issue: adding amps to all preamps or preamps […]

The preamp conundrum 9

Posted 7 years ago

One of our customers was upset because he loved the sound of our phono preamplifier directly into his power amplifier but then not so much when he inserted his preamp between the phono stage and his amp. His question, naturally, was this: if my preamp sounds great by itself and the phono stage sounds great […]

The invention of MultiWave 2

Posted 7 years ago

Oops. Sorry. This post got left out and was part 1 of a 3 part series – of which parts 2 and 3 have already run over the last 2 days. To complete the series, this first one, the invention of MultiWave, now runs. MultiWave is a feature unique to Power Plant regenerators. Unlike sine […]

Striking Gold 7

Posted 7 years ago

In yesterday’s post we covered part 2 of the MultiWave story and how my experiments with higher frequencies feeding power to the connected equipment gave me breathtaking results in the top end and midrange, but lost midbass and bottom end at the same time. Truly, this was thequintessentialdouble edged sword – but I wasn’t about […]

The double edged sword 14

Posted 7 years ago

In yesterday’s postwe began the story of how MultiWave was invented. We left off at the point where I started questioning what was so sacred about the 60Hz frequency that comes out of the wall socket and started experimenting with higher frequencies in an attempt to “increase” the size of the power transformer inside connected […]

The cure can be worse than the disease 3

Posted 7 years ago

In our comments about amplifier damping and how higher damping factors offer better control of the loudspeaker than that of low damping factors, several of you wrote suggesting that some high damping amps sound cold while the opposite can also apply. This observation has merit but the conclusion that better control of the loudspeaker means […]

Cartridge damping 2

Posted 7 years ago

In yesterday’s post about amplifier dampingwe covered what it meant and what happens when a power amplifier loses control of the loudspeaker – you get differences in amplitude that are anything but accurate. There is another type of damping that I reminded of: cartridge damping. Phono cartridges have a problem similar (and for the same […]

Damping factor 7

Posted 7 years ago

The damping factor of a power amplifier is a metric used to describe the amplifier’s ability to control the loudspeaker. It’s basically calculated by dividing the amplifier’s output impedance into the loudspeaker’s input impedance when the speaker is operating near resonance. It’s a really important number to know when you’re making a decision on matching […]

Two types of customers 4

Posted 7 years ago

I am convinced there are two main types of customers for high-end audio: dealers and end users. If you’re a manufacturer which customer do you design your product for? Both are absolutely valid. Dealers have constant day-to-day communication with end users and collect all the info from them and then ask manufacturers to fill the […]

Visionary vs. engineer 7

Posted 7 years ago

My friend Mark Levinson, the man not the company, is a visionary not an engineer. In fact, I doubt Mark knows how to design anything electronic yet his namesake adorns some of the best loved products in our industry’s history. I find this fascinating because many people I run into seem to believe every nerd […]

Give me a good reason 5

There are plenty of products worth owning but only a very few worth buying and even fewer worth switching. If you have something in your home that works you don’t have an itch to replace it – in fact, you probably never think about it because it works. When the opposite is true you’re on […]

Narrowing down the choices 5

If I walk into a restaurant and open the menu to be faced with 100 different choices: Italian, American, a little bit of this and a little bit of that I have learned it’s time to run and find another. In my experience the more choices on a menu the more mediocre the food will […]

So sorry, we have no bananas 4

Slap in the face 8

Posted 7 years ago

Yesterday I wrote about a new power amp technology that simply blew my skirt up to the point where I have cleansed the listening room of anything but this product to amplify the Maggies. The decision to consider doing this took about 10 seconds: I knew immediately this was it. I then spent nearly a […]
