Ellington gems

Ellington gems

Ellington never ceases to amaze and suprise me. Witness this short piece, released by Storyville earlier this year: "The Lake", part of his suite "The River", and performed at the end of a 1969 concert. Here are the Storyville notes:    "On November 7th, 1969, Duke Ellington and his orchestra played two concerts in Rotterdam, in the famous De Doelen concert hall. The second concert of the evening was prolonged, as the public wouldn’t let Ellington go. So while the rest of the bandmembe

Japanese greetings

Japanese greetings

At this time it is relevant to reflect on the merits of japanese-style greetings. Respect can be shown to others while avoiding the traditional western handshake.    Bowing can start when you first see the person at a distance, and continue as you approach them, but has to stop at a one meter distance !   Avoid the mistakes of Trump and Obama.

A simple solution to all problems ?

A simple solution to all problems ?

Reading AustinPop's excellent review of the EtherRegen I could not help but thinking - does it need to be so complicated ? Cascading switches, linear power supplies, audiophile network and DC cables, clocks - there has to be be a better way ! Call me naive, but I believe there is always an elegant and simple solution to all problems, and don't see why digital audio should not conform to that rule. If we have not found it, then we need to look harder

Remastering quality (for vintage jazz fans)

Remastering quality (for vintage jazz fans)

Here's an example to illustrate the importance of remastering quality.   The track is "Stepping into Swing Society" by Duke Ellington, recorded on January 13, 1938. I love the title !   Here's what Eddie Lambert has to say about this track (in "Duke Ellington: A Listener's Guide" - a little publicity for this great book:https://www.amazon.com/Duke-Ellington-Listeners-Guide-Studies/dp/0810831619 ) :   "By early 1938, the swing era was well under way. and Ellington in

my simple system

After spending quite a few years experimenting with various components, I finally have a system which satisfies me, so I thought I would describe it and explain why.   Speakers: Davis Courbet 4 (http://www.davis-acoustics.com/en/courbet-n4/) Amplifier: Lavardin ISX (http://www.lavardin.com/lavardin-isE.html) DAC: ECDesigns MOS16 DAC (https://www.ecdesigns.nl/de/info/mos16) Source: ECDesigns UPL (with ElectroTos cable) (https://www.ecdesigns.nl/de/info/upl16)

The where and why - a time and place to build

Some three years ago I resided in the state of California. ...     After arriving in Nampa it was time to get serious and find a place that would house my ideal system. This actually became an obstacle as just about every older home my wife and I looked at were not planned well for an entertainment room. I mean, low or high ceilings? Hard or soft carpeted flooring? And then there was the main issue the wall for the entertainment system. Floor plans, arrrggghhh for new homes I could not

USB and Other Digital Cables Round Up as of December 2019

USB and Other Digital Cables Round Up as of December 2019 Follow 0     This round up of USB and other digital cables is gleaned from various audiophile publications and Internet articles that I have happened upon over the years.  I hope my fellow audiophiles will find this round up helpful, for instance, when narrowing down choices for a cable purchase.       There are two sections:  USB Cables and Other Digital Cable

Remote locale in NW Wyoming using 4G/LTE cell service for TIDAL

T-mobile allows unlimited "Tidal "HiFi" and "Master" lossless streaming (without data cap) on its cell system with 4g/LTE. We have no Wifi or Fibre optic available in this remote area  obviously power that is  severely and constantly line conditioned.    The CCK adapter works well but was wondering if there is a dpnp or server ios app that could "throw" the content to a Mac Mini  or Grace digital tuner  then to  our DAC.  The ability to use the iphone in hand would be preferable to being wi

mpd-monitor: realtime monitor of an audiostream from source, through mpd, to alsa and your DAC

Dear fellow audio enthusiast,   Today I published a first draft of mpd-monitor, a minimal load and realtime monitor of an audiostream as handled by mpd. A screencast says it all:       Details and documentation are available at the gitlab repository: https://gitlab.com/ronalde/mpd-monitor/. When you experience bugs or issues, which will be the case, please submit those in the gitlab project.   I would like to hear your thoughts.   Happy list

What is all this new disk stuff? -- M.2, NVME, Optane

Over the last few years the form factor for mass media storage devices has started to evolve.  PC motherboards and many laptops now have SSD (Solid State Drives) as their primary non-volatile storage.  The computer industry invented the NGFF (Next Generation Form Factor) system which is now called M.2.   The M.2  interface is directly connected to the bus structure of the computer.  This dramatically improves the speed of operations.  One of the largest improvements is the NVMe  protoc

The Elephant in the room -- The Room!

The Elephant in the room -- The Room!

The predominant factor in our sound system is the room.  The shape of the room, it's size — the ratio of the sides, the construction materials, the openings to the outside and inside.   Then we have the contents of the room, the selection of the speakers and their placement.  The furniture, the people and their placement are next in line to address.  It is a wonder that we can get our systems to sound right!  What is right?   I have been on the inside and the outside of this

The Human Factor in Audio Systems

The Human Factor in Audio Systems

In a couple of responses to one of my blog entries there were some thoughtful comments about how we humans perceive sound and changes in sound.  Human perception is a very complex and is subject to many influences.  I do not pretend to understand them.  The influences around us are sometimes very hard to recognize. Things like confirmation bias are very real.  I want to at least recognize the fact that there are things that influence our perception that we should try to understand.

The Power Supply

The Power Supply

Powering electronic equipment is an area of great research in virtually all electronic systems.  Designs that waste less power, run cooler and manage fluctuations of voltage and current to provide “clean” power to our devices are very important.   We hear a lot about the LPS (Linear Power Supply) and the SMPS (Switch Mode Power Supply).  In GENERAL it has been shown that high quality Linear Power Supplies improve the performance of audio equipment.  An LPS design can be rather simple.

HDMI

HDMI

The High Definition Multimedia Interface (HDMI) standard has overshadowed almost any other means of providing a digital video signal from a source to a display.  It combines video, audio, control and more in a single cable and connector.  The standard has been evolving since it's inception.  The electrical properties of the cabling have changed and a whole lot more.  The standard is controlled by a single entity, and they are almost rabid about enforcing licensing.       While the idea

Burn-in, Break-in

Burn-in, Break-in

I am sure that many of you have been told to be careful with your car or your new lawnmower to break-in the engine properly.  You manage speed, vary the load, etc.  until there are a certain number of miles or hours.  The oil is changed early, etc..  Many mechanical devices need this period to run properly over the long term.   https://en.wikipedia.org/wiki/Break-in_(mechanical_run-in)   Electronic and electromechanical equipment has some of the same needs.  The mechanism is

Music Server / Streamer

Music Server / Streamer

Servers, Servers everywhere but not a bit to drink!   As I outlined when talking about the DAC, music data is sent serially to the DAC.   I like the record player analogy.  The stylus on the turntable is transferring what is in the grove at this very second.   So what does the server or streamer do?  In the most basic form, it provides the user interface to operate the software.  That software then reads the data from the local hard drive, or it connects to an online service
