Update - WIIM mini HD Streamer - a success story

Update -  WIIM Mini Streamer: The WIIM Mini Streamer is a cheap - puck sized - device for streaming Hi-Res Audio up to 192kHz/24bit from your home network or mobile phone to your DAC or preamp. It is a budget wise investment for multiroom scenarios - think  BlueSound Node or Sonos. Plus, it is easier to setup than any RPI3/4 solution. The device was bought chez Amazon France for 99 Euros in April 2022. For the record: I have had two trips to Germany, a quite miserable Covid infecti


DuckToller in Streamer - DAC

Saturday evening was a testing one.

The setup of the device via Bluetooth using the WiiM HOME app did work smoothly. But I rather like BubbleUPNP for playback cues. JRIVER and FOOBAR detected the device sans fault. Checking out the killer feature of the WiiM, the 24bit 192 hz digital output to an external DAC. It didn't work at the beginning  with native bitrates, but worked well with 24bit 96hz, though. Or with down sampled streams from JRIVER or BubbleUNPN. As it didn't work out with the Toslink cable provided by

TOSLINK - I stand corrected!!!

I stand corrected: The Toslink cable provided by WIIM does work with 24bit - 192 kHz files. Just tested it together with the two new short digital cables that arrived yesterday, no difference by performance except for my personal Bias for the shortest one of 50 cm. It's quite handy ;-) Possible reason for my fail: Firmware update in the meantime or multiple human mismatch. Prefer the first option ;-) However, it is important to underline that you won't need to add another cable to

Pretty much excited to get the WIIM mini Airplay 2 in my hands tonight.

The NPR Curious Listener's Guide to Jazz

What a better way to celebrate the passage of time (New Year), from a musical standpoint, than with Loren Schoenberg, musician, Jazz scholar, former director of the National Jazz Museum in Harlem.   His book "The NPR Curious Listener's Guide to Jazz" (https://www.amazon.com/NPR-Curious-Listeners-Guide-Jazz/dp/039952794X) is a great introduction to Jazz, and an opportunity to discover or learn to appreciate many artists through  Schoenberg's insightful and informative comments.

Ellington at the Sunset Ballroom, 1957

Duke Ellington's "All Star Road Band" album was recorded live at a dance in the Sunset Ballroom, in Carrolltown, PA, in June 1957. It is not among his most famous, but is interesting in several aspects.   -- The Music --   There are relatively few albums of the Ellington band performing at dances, the most famous being "Duke at Fargo", recorded in 1940. Fast-forward 17 years and we have with the "All Star Road Band" album another dance date, but with a more "modern" vers

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

Video clips of interest ...

Just noted this one, demonstrating an nominally high performance DAC,     Unfortunately, very strong system signature - quite obviously this is playback; has a "boxed in" quality, for a start. Unlikely to be caused by the DAC - note how the backing strings lack the sheen that this part of the mix should have.

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?

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

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
