Future-Fi

I started this piece in response to an inquiry from younger friend Matt who is considering purchase of a nice audio system. Said friend is a professional software engineer currently at FaceBook, moves with some frequency, who has varied musical interests having played trumpet in high school bands, and guitar and bass off and on, and has fairly eclectic musical interests.

I don’t know if he will trade equipment as frequently as he trades jobs. I’m guessing simplicity is important, durability to withstand moves, durability to withstand loud playback, and non-fatiguing reproduction of the various metal genres. This may mean rolling off the high end in playback processing to loose some of the distortion harmonics.

My financial advisor is also interested, initially as a headphones listener but maybe as a speaker listener. He has a largish home and could probably find a room to use as a listening space. He’s currently an iPhone streaming user who has outgrown ear buds and would like to move up to headphones. He’s married with children so spousal acceptance and resistance to acts of children are factors. The children are at an age where they can be introduced to music listening.

Read on to learn more about building a high performance audio system able to play a broad spectrum of musical genre and styles. The material after the break reflects my experience from 50 years in the hobby, my evolving taste as a music fan, and directions in the modern component audio system industry.

Holiday Letter

Ahoy 2020!

Happy Yuletide. It is time for the yearly Yuletide letter. I rather like the notion of Yule, the pagan winter solstice holiday. Most of the things we enjoy about the Yule season have their roots in Germanic Pagan traditions. Thinking it would be nice to have some music while writing this, I went noodling about in Roon starting with George Winston’s Winter Solstice record. It turns out that George has quite a catalog and that some of it is top shelf.

Roon catalog entry for George Winston’s December

I’d always looked askance at George Winston’s music back in the day because it was in the new age section and and most things in that category were uninteresting. But, this time of year, a good chill tune is appreciated. These are slow straight ahead improvizations. If by another artist like say, Kieth Jarrett, they might be called jazz instead. In fact, George Winston is a noted interpreter of jazz composer and pianist Vince Guaraldi’s music. George’s best records feature Vince’s compositions. As I listen to December, I’m recalling the Lost Songs of St Kilda.

Nick 22 May 2006 to 03 December 2019

Nick was an incredibly brave greyhound and tried his best to be Nick to the end but a fall tore the skin over his hip. In an elderly dog, this injury is irreparable so it was time to let Nick go. This is a classic consequence of hip hyper–extension that tears the skin horizontally and can tear the joint capsule. So Nick left us at home on 03 December.

Nick was eating less than his maintenance

Nick was eating his full ration most days. He was a grazer and Missy was a Hoover-hound so I had to take up his leftovers and offer them later which was driving Missy wild.

I was feeding both dogs per the Canidae inactive adult guidelines. Missy is a bit smooth but Nick became increasingly gaunt. Eating most of his ration, Nick was not maintaining weight so I began to look for add-ins that he would eat. I took to feeding him 1/2 cup 3 times a day adding 50 grams of roast beef to one meal and a half-can of canned tuna to a second.

Nick was cleaning his bowl but still loosing weight. I was never successful at stopping this wasting. I’m firmly convinced that his metabolism changed as he aged.

No, they won’t let you know!

Greyhounds will keep on keeping on into overtime. Both Lance and Nick did so. They loose their super powers little by little and also their ability to do activities of daily living little by little. And the progression is one of hills and valleys rather than a steady descent. It was helpful to identify a terminal quality of life but Nick did not approach it linearly. Rather, he’d have good days and bad and good hours and bad. He could appear to be down only to nap for a couple of hours and hop up to follow me around as best he could. It is a myth that they will let you know when it is time.

Some fond memories

I miss my Snarky Puppy. Such a calm dog in kennel, Nick came home an absolute git. He thought the world centered around him and when he discovered that it didn’t, he’d get frustrated and go hose down something he associated with me. Taken to a reunion, he spent the whole time marking and barking at the other greyhounds in attendance. Nick would walk the neighborhood here at Dismal Manor, head in the trees shouting at the squirrels as they laughed at him.

As he completed year 4, Nick managed to shed his sapling ways and become an adult. Just in time for the car trip to Dismal Manor and the motel stay while we awaited our household goods. The marking stopped and a fenced yard let him dissipate some of the energy. Through year 5 and 6 Nick continued to torment squirrels, at first charging them but later stalking to close before the charge. I have a video of him stalking somewhere in the Wayback Machine.

When Missy joined us, Nick gave her one menacing only to be told to play nice. He quickly discovered she was a track fit, track fast 3 while he was nine. Nick would withdraw to the carport when Missy went ripping about the yard. After that one testing of limits, each would take the other’s wing as needed. Sadly, they never played together. But when one called Tally Ho, the other would come running to support. For late night turnout, they’d go together. The first would wait for the second to join.

Missy adjusts

Missy is doing well but she misses Nick’s company and support. She’s needing more play time and more cuddle time (an OK thing). She’s also driving the plan of the day. She raises sand when it is meal time and treat time. I’ve introduced some indoor ball play with the big fuzzy Chuck-It and give her evening treats in a treat puzzle toy.

Another?

Maybe. I’m 71 so my next would be with me into my early 80’s if I adopted a track hound. I also have the option of adopting a displaced hound. Our local rescue is winding down so James River Greyhounds is serving the 757. James River are better prepared to take a group of dogs from the track, house them, and distribute them. They affiliate with Greyt Love Retirement who operates a small kennel, has a hauler, and brings dogs to the area for adoption. James River sorts and places the greyhounds.

Ruffwear Boots have Arrived

Nick’s new shoes arrived Friday afternoon. I unboxed them and fitted them. I was pleased to find that my measurements were good and that they fit nicely. Nick let me put them on and has been up and about some while wearing them. This article covers the initial boot use experience and some issues we discovered. It has grown over several days.

Blue Suede Shoes Update

Nick continues to experiment with footwear. In the previous episode, I mentioned that the RuffWear boots I bought 14 years ago were moving around so the slippery part was down. Upon investigation, I discovered that his boots were the old size L(arge. They are a good inch wider than his foot allowing them to roll.

Nick in original RuffWear boots

Since I bought those boots for Nut, RuffWear has redesigned the product line. The new boots are sized in 0.25 inch increments and sizing instructions are to measure foot width and buy the size closest to but smaller than the foot width measurement. Measure all feet to be shod and use the largest size. Nick measures 2.125 inches so he’d wear a 2.0.

So, today I ordered RuffWear Summit boots in bright green.

Don’t You Step on My Blue Suede Shoes

I’ve been trying to find things that help Nick with his 13.5 year old mobility. Nick had been eating less than maintenance for some months loosing a good bit of hip and shoulder muscle. The muscle loss has impaired his stance and gait. Most commonly, his feet slip outward causing an unplanned split. What might help?

Alternative Twitter Apps

With the advent of iPadOS and development work at Twitter, Inc. the iPad Twitter app has become unstable. As of iPadOS 13.1, multiple users are seeing the following problems.

  • Each time the app is updated, view mode switches from the most recent to “Home” view. Most users prefer the timeline view.
  • In both home and timeline views, the app interrupts what you are doing to refresh the view.
  • The app segfaults at random
  • The app hangs in the tweet editor
  • The app segfaults in the tweet editor

In this article, we’ll look at an alternative Twitter app. There are two well regarded apps, Twitteriffic and Tweetbot having similar user interfaces and none of the rude behaviors mentioned above.

Nick’s Hindquarters Weakness update

The past several months have been up and down and up again as we learned more about Nick’s late in life care. This article is a catch up to November. I never thought he’d make it that far.

Schiit Pi?

Those of you who saw the John Darko interview of Jason Stoddard and Mike Moffat filmed at the 2018 RMAF know that both have a passion for Schitty puns. During this interview, Mike teased a “Schiit Pi” concept. Mike’s idea was to embed an ARM processor in products to pick up additional digital signal processing tasks beyond the abilities of the Burr-Brown parts he had been using.

Jason is adamant that Schiit will not become a “software company”, that is offer IOS and Android apps or make devices having a significant user interface say like Roon Controller or Volumio remote. The ongoing maintenance of these products is simply too costly for the Schiit minimalist value first design esthetic.

A Minimalist Streaming Player

So can we make a minimalist streamer using a hatless Raspberry Pi? If we did, how would it sound? This product is as basic as a Roon Player can get. It turns out to be a very good one. Will Jason put it in the catalog? Probably not. Volumio got there first with more software integrated.

Those not wanting to tinker with hardware and software will find Volumio Primo a good alternative that provides a SBC and DAC supporting AirPlay, Rune, Roon, Spotify, and others but excludes the headphone amplifier. John Darko’s review is excellent and he likes the sound of Primo and the value offered. Primo is comparable, maybe not quite as sweet as the Allo Digi+ Signature. However, the ALLO devices requires you to bring your own DAC.

More Schiit — Modi and Magni

The Moocher had been mixing church service recordings using the DAC and amplifier built into his 2017 5k Retina display iMac. This sound is not bad but not the best. After a year of fatiguing sound and an inflating checking account, it was time to purchase something better for the desk. Having Gumby aboard for 9 months, what better choice than Schiit’s Modi and Magni. These two $99 products account for 1/2 the company’s revenue.

So, $200 gets you a complete personal audio system less speakers or headphones. How does Jason perform this magical feat? (The Moocher is pretty sure Jason has been to the Highway 51 Crossroads.) First, the design is minimalist, just the bits needed for brilliant musical reproduction are present, no less and no more in this music first design. Point of sale graphics, fancy cases, auto input selection logic, etc are all left out in favor of a sophisticated circuit topology, carefully selected components, and quality construction and testing. Second, they sell direct. No distributors or retailers adding vigorish. Third, they have low failure rates resulting from careful design, design testing, quality builds, and build testing. Everything runs for a day on the burn in rack to catch weak parts or assembly flaws.
