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.
Electronic and electromechanical equipment has some of the same needs. The mechanism is
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
I love acronyms, but these are a mouthful.

The standards were co-developed for the consumer / professional markets. They define both the data transmission formats as well as the connectors and cabling used to connect devices to transfer digital audio. These standards include stereo and multi-channel audio formats.
Digital to Digital conversion is a "process" that translates one type of digital into another. D to D conversions have multiple use cases such as converting USB to SPIDF or I2S.
One example of this kind of device is the Sonore UltraDigial. Another is the Aurender UC-100. You can visit their product pages for more information.
In modern networking, there are multiple media types including various types of Ethernet, Fiber Optic and Coax cabling. The Small Form Factor (SFP) transceiver is a standards-based device that is used to allow different physical network media connections to network devices such as switches. SFP has a standard mechanical and electrical interface for interchangeably.
Many applications of the SFP are for fiber-optic network connections that provide electrical separation or long distan
Welcome to my first Analog Wednesday! "Stuck in the Middle With You" With apologies to "Stealers Wheel."
DAC's to the left of me, Speakers to the right, here I am, Stuck in the middle with you
I do not want to leave out the parts of the system that make the sound! In a file-based or digital music system something has to make the air move, and that is the speakers. (OR Headphones). Working upstream from the speakers we need amplification to power the speake
USB stands for Universal Serial Bus which is used to connect peripherals to computers. USB is used for data transfer, audio, power delivery and more. The USB standards group has released three major versions of the standard.
In our daily lives, we use USB to charge all kinds of devices. The mouse and keyboard on your computer probably use USB interfaces in one way or another. We synchronize or transfer data between devices such as printing or file transfer to disk drives. The USB
The DAC is the heart of a file-based or streaming digital audio system.
Storing music or video for that matter in a digital format has some significant advantages. The physical space needed is trivial to non-existent as a problem. There are a lot fewer issues with long term storage such as moisture problems, print-through on magnetic tape and many more. Digital also makes the effort of copying and transferring content almost zero. File-based storage of music brings up issues
The NAS (Network Attached Storage) is a type of computer that, in general, has a single function. It contains some form of data storage devices such as disk drives or SSD devices. The primary purpose of a NAS is to make the information stored on the drives available to other computers on the network through file sharing. Ordinarily, the user interface is via a web browser.
Over time the operating system and applications on NAS computers have gotten more powerful. Companies such
I just made an account here. First post. I'm a 26 year old musician/producer/mixer. I started taking interest in audiophile questions about two years ago, stemming from a quest for dead-accurate monitoring. I've been all over the audio internet, and I've heard a good deal of systems in person. Audiophile and pro, analog and digital, cheap and expensive. It's funny how the audiophile world and the pro world don't really like to mix, even when they're taking interest in the same questions.
Nicky Hopkins (1944-1994) was one of the best keyboard artists of the classic rock era. He passed at only 50 years of age, much too early. He worked with the Kinks, The Rolling Stones, The Who and many other groups.
Listen to Sympathy for the Devil on the Beggars Banquet album and you will know what I mean. Maybe the best rock piano track ever.

Over the last couple of years I converted my compact disc collection to digital files. This allows me to enjoy the music in whatever venue I happen to occupy: car, living room, basement lair (aka the "country bunker"), MARC commuter train, interplanetary shuttle or molecular transport. No need to lug the discs and player with me and through the magic of miniaturization I simply plug a Audio
Relf was 33 when he died from electrocution, in the basement of his home, while playing his improperly earthed (electrically grounded) guitar. Relf had dealt with several health issues throughout his life, including emphysema and asthma, which may have contributed to his inability to survive the electric shock.
If you have ever heard the Yardbirds version of (H. Wolf's) "Smokestack Lightning" Kieth did the harmonica solo. Maybe the best harmonic solo ever.
Thanks Mr. R
People have asked how I go about sorting out systems - and find my answers very unsatisfactory. Well, I have come across a book which very nicely addresses some of the key areas where I find a lot of the issues arise - and gives a lot of suggestions of very, Gasp!!, technical gear that can be used to chase these things down. It's a very practical book, minimum high falutin', equations for equations sake guff - what I find especially endearing is that there are a lot of cheap and cheerful tricks
