Audio for dummies (part 2)

I was wrong, there is hope - though I'll never fit the Duke Ellington Orchestra in my living room, I may be able to get in the studio with them. Well, not quite, because they would have had to record with modern technology in high-resolution (192 kHz ?)...   Here's a session I would have enjoyed: "Jazz Party", at Columbia's 30th Street studios. Dizzy Gillespie dropped in, as well as Jimmy Rushing. The original LP was released with applause added in. Another version is available without

Audio for dummies (part 1)

Monday was not a good day for me.  I was told this:     My hopes to recreate the Duke Ellington Orchestra in my living room were shattered... I knew my 2000€ speakers were not quite up to the task, but I was hoping that perhaps investing a little more in my system would somehow get me there. Reading review after review on this very site (and many others) I had been led to believe that I would experience the music as if the performer was in the room.   Maybe I should fin

ECDesigns' PowerDAC-R - wrap up

Five months after posting my initial "preview" of ECDesigns’ PowerDAC-R I would like to offer some concluding comments on my experience with this unique product.   I will also include additional information that was provided by ECDesigns in answer to some of my questions. Some of this information may already have been mentioned in the long ECDesigns thread on this forum, but it will be convenient to have it available here for future reference. Even if one does not grasp all the techni

The Purpose of Audio Reproduction

Time to crack this back open again, 😄.   Yes, what's the point? There could be a zillion answers, but my answer is to be true to the contents of a recording ... I was going to post this to that unloved thread, now gone to zombie land, but I'll do it here, instead,     Bit of a mess, eh? And, this is the remaster, from 2015!! - I've got it on a double CD from 1998 - a low cost release - sludgy, plus? ... You bet!   What should a system do to, for this?

ECDesigns PowerDAC-R preview

It’s been a long time coming…   ECDesigns is a two-person operation run by brothers John and Gordon Brown; John handles circuit design and Gordon oversees the programming aspects. They are based near Eindhoven in the Netherlands, and products are sold directly through their website (www.ecdesigns.nl). John Brown introduced himself on DIYAudio in 2006 with these words: "I have spent my entire life designing, repairing and building electronic equipment – electronics is my passion...

Objective subjectivism

Objective: expressing or dealing with facts or conditions as perceived without distortion by personal feelings, prejudices, or interpretations (Merriam-Webster)   Arthur Salvatore is an old-timer with an outdated website that contains many fascinating insights into audio. My favorite section describes his "audio philosophy". One aspect which can be put in practice by all of us, concerns his description of "levels of audible improvements":   http://www.high-endaudio.com/philos

A speaker cable to rule them all ?

Ever tried copper foil speaker cables ? I have experimented with a couple recently:   - DIY model - Silversmith Audio's Fidelium cables   1) DIY copper foil cables   They are easy to make yourself - here is a recipe someone gave me. All you need is: - Kapton tape (https://www.amazon.com/Temperature-Resistant-Polyimide-Sublimation-Soldering/dp/B08T74TCFS/ref=sr_1_14?dchild=1&keywords=KAPTON+Tape&qid=1618095371&sr=8-14) - Copper foil, 16AWG

A custom music application

I am always curious to understand how people manage their music collection, and often surprised by the creativity deployed by some.   Perhaps reading about what I have designed will be of interest to others, though it is build "from scratch" and hardly replicable "as is". I'll admit that I am quite proud of my work: the results meet my specific needs.   I gave Roon a try for a couple years, then gave up, explaining why here (good background on why I embarked on this project):

RIP Marvelous

Marvelous Marvin Hagler, one of boxing's all time greats, just died, aged 66.   His boxing record: 67 pro fights, with only 3 losses (all controversial). He elevated boxing to an art form as few have ever done. From his interviews after his retirement, he seemed like a kind man. He remained bitter about the world of boxing, having been robbed in his last fight of a well-deserved victory against the more popular Sugar Ray Leonard.    Anyone interested in the "Sweet Science" sh

More Ellington Gems

The Pittsburgh Jazz Festival organized on June 20, 1965 a "Jazz Piano Workshop" which was luckily recorded and issued on CD by Mosaic Records: https://www.discogs.com/Various-The-Jazz-Piano/release/5260834. Here is a picture of the "cast" on that day: https://collection.cmoa.org/objects/cfcdaea2-de64-4f61-92cf-8f4e6d9db60f   Ellington plays two numbers (in addition to a duo with Earl Hines): a spirited version of "Take the A Train", with bass and drum accompaniment, and another piece "

Lady Day

In 1946 Hollywood made a film about Jazz  - "New Orleans" - and cast Billie Holiday, arguably the most influential singer in Jazz, in a secondary role as a servant.   Yesterday, Hollywood celebrated Andra Day's depiction of Billie in the biopic "The United States vs Billie Holiday". Times have changed (though it could be argued there is still much progress to be made), but Billie Holiday is still remembered today as a "tragic" figure, somewhat obscuring her lasting contributions to Ame

ADNACO-S3B USB 3.0/2.0 OVER FIBER OPTIC EXTENSION SYSTEM

https://www.adnaco.com/products     Adnaco Remote host USB system is a PCIe to USB extender.  There is a  PCIe card that provides two USB 3.0 ports extended remotely by Fiber Optic Cables.   In an audio PC, this removes the USB interface from the noisy PC motherboard.  For better audio, use a high-quality power supply on the endpoint. I have found that this interface provides significantly improved sound quality vs. the USB ports on a typical PC Motherboard. Adnaco

The new Airpulse A80 & Airpulse A300 pro

There had been members suggesting more reviews on active bookshelf speakers after the Airpulse vs Kanto reviews and when Airpulse asked me about reviewing the new A80s I felt it would make sense to report about them here in the forums.     Last  week I have received the fancy blue coated A80 active desktop speakers from Airpulse, they are the smaller sibling of the already reviewed A100 and sell for 699 USD. These two may have some smaller technical differences only, wh

Like a late November afternoon sky: About DACs and smartphones - an opinion:

Could we relate to DACs performance somehow like to a fall afternoon’s beautiful cloudy sky? I assume It may lie in the eye of the beholder which picture carries more beauty for him or her while obviously there are objective criterias to define a picture's qualities. For example, I’ve selected 2 fall sky images I took with my then smartphone in  2016 and 2018 The technical quality is limited, the impression may suit you or not. But is as much in line how I saw the sky as I could c

USB and Other Digital Cables Roundup as of July 2020 Revision 1

Introduction Sources for the digital cable roundup include the Internet and audiophile publications and are mainly "Recommended Components" lists, "Editors' Choices" lists, and audio component reviews that mention the digital cable included in the reviewer’s own stereo system.  These are lists and reviews I have happened upon over the years.  I have no doubt overlooked many lists and reviews, so let me know and I can include them next update.    If a cable is mentioned frequently

Introduction Sources for this cable roundup are mainly "Recommended Components" lists, "Editors' Choices" lists, and audio component reviews that mention the digital cable included in the reviewer’s stereo system.  If a cable appears frequently and over several years in these sources, my theory is that it may very well be a superior cable and worthy of consideration.  I hope that my fellow audiophiles and music aficionados will find this roundup helpful, for instance, when researching and s

Loren Schoenberg on Ben Webster

Loren Schoenberg (of the the National Jazz Museum in Harlem) has published a four part lecture on Ben Webster on YouTube.    The production is not of the highest quality (but the content easily makes up for it), and some of the tracks are better heard on youtube directly or from your collection, if you can find them. There are quite a few rarities.     Part 1:     Part 2:     Part 3:     Part 4:

In Praise of Ellington - The Pianist

Duke Ellington recorded music for 50 years.   Ask any Ellington fan to pick their favorite album, they will not be able to decide. Ever changing, throughout these 50 years, but always distinctive, what is it that makes Ellington so special ?  His arrangements, his compositions, his ability to gather in his band the best talents and use them at their best ?   One aspect which I find fascinating is his piano playing. His style and sound is instantly recognizable, and forms the
