Roon Take 2

Post author By davehamby
Post date March 21, 2018

Abstract

Over the past several months, I fell in love with Roon, its ability to stream my digital music collection in pristine full definition audio, the Allmusic artist and album commentary, and Roon Radio, the ability to play other things from my library like what I had been listening too. Nothing offers this combination of features. Nothing appears to have the commercial traction of Roon.

This article serves several purposes. First, it is my working notes from rebuilding my Roon environment, an iohyve managed FreeNAS behave VM. Second, I offer this in the hopes that it might inspire others to home brew. This article is a bit advanced. You really need to have a year or two of Unix system integration experience to pull this off. It is not a character by character, click by click recipe to build a Roon Server.

Those who don’t have system integrator chops but want a quality music server should consider the Roon Nucleus described in Reference [4]. Roon has developed these robust system specifically for the music serving task. They have adequate storage and computing resources to run Roon Server and are designed not to sneak crud into your audio system over the USB ground. If you’d like a fancy panel with that, Bryston, Linn, Naim, and others, will make pretty metal for you.

The recent revelations centered around Facebook and Cambridge Analytica compel me to bring this relationship to an end. Yes, Facebook, it is you.

Buggy iPad app
Buggy iPad messnger app
Only trolls are participating. Everyone I want to hear from is a lurker
You aided a hostile foreign power’s information warfare campaign directed at the US electorate, a campaign that probably resulted in the election of the worst US President ever.
You allowed an advertising client to plunder 50 million user’s profile information
Said advertising client left that information lying about on open or easily penetrated servers

So on Passover, the account goes.

Introducing YouMail

I’m impressed. Favorably impressed. StraightTalk was OK but ATT, my MVNO carrier had gotten lazy. StraightTalk was not offering ATT visual voicemail, data tethering, or WiFi calling.

Changes in ATT’s ranking in Consumer Reports prompted me to change from StraightTalk to Ting. Consumer Reports ranked T-Mobile above ATT as a carrier and Ting above StraightTalk as an MVNO. StraightTalk is a competent discount MVNO but had not been keeping up on ATT LTE capabilities rollout. The Ting rate plan model offers data tethering, WiFi calling, and visual voicemail across the board.

The Moocher welcomes Ting Mobile

Ting Mobile has surged to the top of Consumer Reports wireless carrier popularity survey. Ting is a mobile virtual network operator (MVNO) serving the continental United States reselling T-Mobile and Sprint service in its service territories. Coverage is the same as the parent carrier. If you’re in town on or a major road, life is good. In the prairie or the mountains I can’t hear you now but I am never there.

Why did I change

The incumbent MVNO operator was OK technically but known for horrid customer service. Thanks to good articles on GigaOM and Ars, I made it through on boarding with the incumbent without needing to call them. Since then, I’ve not had to call them but I’m finding my website password goes missing from time to time. Most recently, when I started looking at the number porting. You have to mother may I to move your old number. Being a GV convert, i let Ting give me a new number and saved firing the incumbent for another day.

Bond Index Funds

How do bond index funds work? They’re not as easy as stock index funds. Stock index funds own shares of each stock in the index in the ratios found in the index. How do you do that with bonds? Especially when all bonds of a given issue may be held? Read on to find out.

2017 That Was the Year that Was

What a strange year. The first year of continuous scandal national government. Real scandals, not pretend scandal like those during 44’s watch. 45 became in violation of a building lease with the US Government upon inauguration (can’t lease to USG employees or elected officials) and it has been a steady slide from there.

Thoughts on Electric Power for Puerto Rico

Post author By davehamby
Post date November 5, 2017

As you may know, I’m a former electric power utility equipment engineer. Although no longer active, I continue to follow developments in my former industry. Hurricanes Irma and Maria significantly damaged Puerto Rico’s ailing state owned public utility. Because of economic conditions on the island and electric power pricing decisions, the utility has been unable to maintain its generation and distribution equipment. Apparently, the utility was also deferring tree maintenance long its rights of way. Because of the lack of care and the strength of the storms, most of the island’s retail distribution is down and some of its backbone transmission is damaged. Puerto Rico is in the position of rebuilding its transmission and distribution and cold starting its generation.

The Moocher bakes a Raspberry Pi

Post author By davehamby
Post date August 9, 2017

In poking about audio sites, I discovered Roon Labs Roon music server product. Roon is the music server I’ve been looking for for 20 years. Roon Labs has its origins in the Meridian Audio Solooes product over in the UK. This is a highly regarded embed music server organized in proper client server fashion. This post describes Roon, my Raspberry Pi build of a Roon Transport, and the commissioning process. Though not a step by step (see the references), this post includes some lessons learned during the build and setup, and the bandaging of my knuckles.

Listening Experience

After several weeks of living with Roon and the HiFiBerry Digi+ transport, I’m seriously taken with the product.

The composer, composition, and performance reviews are of high quality, written in an engaging and informative style.
Roon Radio is helping me rediscover records and tracks I had forgotten I had. Starting with a Thile-Meyer track, it worked through the album, into Fleck & Meyer, then to Nickel Creek, and Punch brothers and back to Thile-Mehldau. Poor dogs had to listen to acid grass and acid folk while I was shopping.
The Digi+ kit just works with the metal case and HiFiBerry standard power supply. There’s no need for expensive linear supplies or unobtainium wire cryogenically aged in unicorn blood. The DAC is going to jitter buffer, retime, and reformat for rendering and any exotica outside this final device is unable to improve the sound. Save your money.
Parasound got things right with the P5. The Optical and Coax inputs work well. USB input is reserved for disk mastering off my old Mac Mini and Parasound Z-Phono USB. This device has an ADC with line level and moving-mangent/moving-coil phono preamp. And it works as well as the P5 preamp and DAC. John Curl is a wizard!.

I really love the sound of this rig. If the album is well recorded and the mix is phase coherent, Brad Mehldau’s piano notes dance in space from string to string with a Brad and his Stienway are in the lounge sound.
