Quantum Mechanics and Burn-In

I was reading the Zu website, as I have some curiosity about high-efficiency speakers.   This caught my eye first:     If someone wrote that on one of my exams, I would draw a red line through it and mark it "0".   This made me throw up a little in my mouth:       Admittedly this might just be the result of a few too many bong hits, and is not quite as egregious as the claims here: Quantum-mechanical tunneling and cables - Blogs - Computer Audiophile   But, still …

All Amps Do NOT Sound The Same

I'm not one of those "audiophiles" that picks a particular set of good gear, and stands pat for 10, 15, or 20 years. I understand their argument; rather than constantly auditioning new kit, they are sitting back and enjoying music. However...how can you truly be satisfied with your system, if you're not entirely convinced you've got the "best" (sounding) one; respective to your budget of course. Sure...someday (and that day may not be far off) I'll settle-down with just the right combination, an

Mastered for iTunes Part 1

The image below shows a comparison between the MFIT (Mastered for iTunes) and ALAC (Apple Lossless Audio Compression) versions of John Mayer's "Queen of California." This is track 1 from his latest album, Born and Raised. MFIT is on top, ALAC is on bottom.   What do you see? To me, the MFIT version is mastered at a slightly lower volume. I can't see any visual evidence that the dynamic range compression is different: since the loudest and softest parts both appear louder on the ALAC versio

Pussy Riot Sentencing a 'Bitter Blow' to Freedom in Russia

If you haven't been following this story, and are concerned about artistic (or any other form of) freedom of expression, this is about a Russian punk rock group who have been jailed following a sham trial for criticizing Putin.   Amnesty International has adopted the three women convicted of thought-crimes as "Prisoners of Conscience", a designation the politically impartial human rights organization reserves for the most blatant forms of political incarceration.   The full Amnesty Interna

How Notepad Provides Thoughts to Flow and Clutter to Go

I like to refer to myself as a proficient typer, but I by no means can keep up with my brain. Realistically, I would say that I am capable of typing 80 words per minute with about 85-90 percent accuracy; however, my brain works more rapidly than that. Over the years, one thing that I have found to be particularly frustrating is when typing letters, documents for seminars, or speeches, Microsoft Word can be incredibly cumbersome with all of its auto correcting, spell checking, formatting and para

Why I never got that perfect null in difference testing part one

I set out to see what the difference between expensive analog interconnects and cheap ones were. My method was simple in essence. I would send a signal to a DAC, send the analog output over an interconnect, record that digitally with an ADC. Then repeat with a different cable. Take the two digital files and subtract one from the other using software. There was a long thread posted in the general forum about my attempts. I learned some things along the way and eventually could get consisten

Why I never got that perfect null in difference testing part three

Timing in my compared files, how do I compare timing in files?   Clearly none were as much as one single sample off. I had figured out ways to align all files to the single bit. I put one second of silence at beginning and end while putting one bit in the middle of the silence to maximum in the test files. So just record a few seconds before and after. Then align the signals in Audacity and chop off the ends with single bit precision. When the clocks were locked no other obvious artifac

Why I never got that perfect null in difference testing part two

Okay, so difference testing didn't result in perfect nulls with only thermal and flicker noise left. Why not? The most obvious answer is a difference in level between the two signals recorded. With null depths of more than 100 db it takes very little level difference to leave a bit of the music above the noise floor. So I sent simple two or three tone test signals through comparing them. Using the same equipment and cable changing nothing. Had left equipment on for minimum of three full d

DSD on Jriver playback problem

Problem solved. I set the bitrate to 88/24. Apparently the CPU was running out of steam at 96/24. I am frankly a bit disappointed the CAPS 2.0 is not spec'ed with a processor powerfull enough to do this on the fly conversion at 96/24, but that is another issue.

New HTPC and Audio Data Store Solution

Let me start with a little background on my current setup. For my hi-fi listening I have an Auraliti PK90 with a portable hard drive directly attacked supplying my music. For the rest of the house I have an older MacBook running iTunes streaming to three Apple TVs. Right now I am in the process of ripping all of my DVDs to iTunes and would eventually like to get my Blu-Ray movies as well.   My current backup solution is twofold. I have a 1TB USB hard drive attached to the MacBook that has t

Sunday-Morning Music

Welcome to my blog! So...why Sunday-morning music? I've been an avid poster, at another popular "audiophile" forum, for quite some time. My longest posts, always seem to come on the weekend mornings. I get my coffee, and some breakfast; put on some music, and pontificate away, about whatever is on my mind that particular day.   This all goes down, in the owner's section of the speaker brand I favor (which won't exactly be a mystery, going forward; but I don't necessarily want to go and name th

Geting started in CA and the SONORE one year on...

My SONORE one year on, Jim Nuzum (Sydney, Australia)   I’ve lived with my Sonore for almost a year and after some initial teething problems, I’ve gotta say it’s a simply brilliant bit of kit and CA is the only way to go.   Firstly an important qualification: Rather than a formal review of the Sonore unit itself, this is intended to be more of an “essential few steps in getting started toward CA, featuring the Sonore” as a more than capable central source.

The Double-Blind Control Experiment and Scientific Thinking

Edge.org, the website of the science and technology think thank Edge Foundation, has a great collection of answers from various experts to their "Edge Question 2011", "What Scientific Concept Would Improve Everybody's Cognitive Toolkit?" Among them is this great contribution from Richard Dawkins that I think applies extremely well to the audiophile world:   The Double-Blind Control Experiment Not all concepts wielded by professional scientists would improve everybody's cognitive toolk

Stereophile Recommended Components (Class B) versus Logitech SB + Boston Acoustics CD/Radio

I am currently living in Southern Europe. I have had over a long time equipment such as Conrad Johnson, Krell, Muse, Bryston, Snell, Vandersten, etc, etc: Two separate systems. One for Home Theater and another for Music.   Sadly, I now have only a great Boston Acoustics CD player and Radio + Logitech SB. I have over 10,000 CDs stored in NAS.

Remotes, Part II: My RedEye Remote experiences

After messing with a number of different remote control options, including the functionally similar Logitech Harmony Link, the details of which I have blogged previously, I decided to get the RedEye Remote, based in part on Chris's Review of The RedEye Remote, and also because I can run things from the comfort of a desktop web browser.   I've sunk some time into this now, so I am creating a new blog page here to log my experiences, in the unlikely chance they might be of use to others.

Lazy Man's DIY Equipment Rack - No Hand Tools Required

A few weeks ago I decided that I was going to purchase a legitimate audio equipment rack for the first time in my life and retire the old coffee table I have been using for longer than I care to discuss. After scouring the web for over a week I finally narrowed my choices down to one model. So I called my local dealer up with credit card in hand to place an order for a Finite Elemente Pagode Signature in Maple wood finish. The nice gentlemen on the phone was quick to point out how great a unit i
