Audio Investigations: Shades of Tweakdom
http://audioinvestigations.blogspot.com/2015/02/shades-of-tweakdom.html
Wednesday, February 18, 2015. There's a spectrum of potential value in audio improvements and "tweaks.". In any real room, you will be getting some reflection, and reflection isn't fidelity, but some reflectiveness may make for a more enjoyable experience anyway. Most important is the quality of the reflected sound- how much does it change the frequency content of the original sound? And there you have tradeoffs such as trading off the frequency balance of reflection for the total amount of reflection.

Audio Investigations: July 2014
http://audioinvestigations.blogspot.com/2014_07_01_archive.html
Wednesday, July 2, 2014. Converted DSD sounds threadbare. The Denon DVD-9000 will not play SACD. So how do I play SACD on new living room system? Well, of course, Weather Report does use a lot of synths. But then I played Weather Report on the Denon 5900 (re-sampled by the Lavry AD10) and it sounded much more real, I felt, as if missing information had been restored. So SACD/DSD playback actually relies on its own high frequency "noise" to sound real. Posted by Audio Investigator. Dan The Man audio blog.

Audio Investigations: High Resolution is not Fake Snake Oil
http://audioinvestigations.blogspot.com/2015/02/high-resolution-is-not-fake-snake-oil.html
Wednesday, February 18, 2015. High Resolution is not Fake Snake Oil. High resolution PCM recording is measurably better. There is not a myth, you can look at the actual measurements of real equipment using the best test equipment in many Stereophile reviews by John Atkinson, who has published detailed measurements of more equipment than anyone, over three decades of reviewing and editing the most popular high end audio magazine. Now, in many cases the Actual Mastering done on a high resolution recording ...

Audio Investigations: Using the Audio-GD DAC 19
http://audioinvestigations.blogspot.com/2015/05/using-audio-gd-dac-19.html
Sunday, May 17, 2015. Using the Audio-GD DAC 19. So when the Audio-G D DAC 19 came back on the market as the Anniversary Edition, my only question was how many to order. I decided to play it safe and just order one. What if it didn't meet my expectations in some way? What if it had the oily chemical smell as I have found with many products made in China? Which leads to speculation about where this smell comes from. Is it a preservative added to rubber and vinyl? Is it an insecticide? I bring this up not ...

Audio Investigations: AF/RF Spectrum Analyzer
http://audioinvestigations.blogspot.com/2015/05/afrf-spectrum-analyzer.html
Wednesday, May 13, 2015. I've already got one ( 50kHz) HP spectrum analyzer. But now I think what I'd like would be an 8566B, which has range from 100Hz to 22GHz, and minimum 3Hz bandwidth. BTW, HP instruments became Agilent when HP sold off it's original instrumentation business to become a PC maker. Agilent later reorganized to separate out medical devices and now the instrumentation business is called Keysight Technologies. Posted by Audio Investigator. Subscribe to: Post Comments (Atom).

Audio Investigations: April 2014
http://audioinvestigations.blogspot.com/2014_04_01_archive.html
Wednesday, April 30, 2014. SVS Sledge replacement amplifier ordered. At work on Monday I scanned my email to determine that I bought my first SVS PB13 in May of 2008. I assumed (incorrectly) that there was a 5 year warranty (actually it is 3) but even with 5 years, I would not be covered, unless this was actually my second PB13 (which is still over 3 years old). Posted by Audio Investigator. Friday, April 18, 2014. The SL 1000 Mk2 Dustcover. Anyway, here are the measurements:. Posted by Audio Investigator.

Audio Investigations: December 2014
http://audioinvestigations.blogspot.com/2014_12_01_archive.html
Friday, December 26, 2014. Why not to bother with listening tests. Peter can be a bit over the top. But against the matra, "listen for yourself," I think he is almost entirely correct. There is most often little or even negative value in "listening for yourself." And I can say different things than he does. But if I find them fun to think about, why not have them in play anyway? Or why should I deprive myself the fun of buying and deploying fancy gizmos regardless of my doubt over their efficacy? I tempe...

Audio Investigations: Modex Modules
http://audioinvestigations.blogspot.com/2015/05/modex-modules.html
Friday, May 8, 2015. Modex modules from RPG are available tuned to 40, 50, 63, 80, 100, and 125 Hz. Anyway, back to the original post. Even Modex may not actually be Helmholtz Resonators…that terminology does not appear in anyones description. But at least they are tuned and therefore resonator-like. B&H Photo sells (special order) a pair of Modex 40Hz corner traps for $684. Winer's charge about Modex being expensive would definitely apply to the Modex Metal Plate absorbers for $1944. That Class A Feeling.
