Why I Switched To Roon And You Should Too

I’ve been running my music system at home using Squeezebox Server software for many years. It has served me well, but Logitech bought the entire eco-system and then abandoned it. Because it’s Open Source, it’s still updated, but it’s time to do an upgrade to a better system. After testing a lot of different server solutions, I finally choose Roon by Roon Labs as my music server software. Here’s why. ...

HifiBerry DAC+ Click When Changing Song

My current music setup is a Raspberry Pi 3 with a HifiBerry DAC+ audio card as my music player. It works perfectly, except for one annoying thing. The new HifiBerry DAC+ makes an audible click or poping sound when changing the sampling rate. I have a lot of recordings in higher resolution than CD-quality of 16-bit 44kHz, so it’s jarring when it happens. I like to play my music loud which exacerbates the problem. But there’s an easy solution, and at the same time, you can get better sound quality overall. Here’s how to fix the problem. ...

How To Destroy a Record Mastering

With the resurgence of good Hi-Fi, where more and more people buy good headphones and listen to a lot of music thanks to streaming, it’s sad to see the things the mastering engineers (and in the end the artist) do to music. The recordings are getting worse. Even old records that get the “Remastered” or “Expanded” treatment doesn’t sound as good as the original. Why? ...

Apple Music Streaming – It's a No Go For Me

Apple Music So I gave Apple Music streaming a try. Being able to just search for music and add it to my playlists sounded like a good idea. After a while the recommendations becomes rather good as well, giving me some tips of other bands I might like. But here’s the problem I have with Apple Music. When you sync your music via iCloud, you can no longer sync music via iTunes! And to be able to download music locally from Apple Music to your phone, you must use the “in the iCloud” solution. Catch–22 anyone? ...

Raspberry Pi Car Audio System

My Raspberry Pi Car Audio Player A lot of people are using the excellent Linux microcomputer Raspberry Pi and install it in their cars. Usually, they use a color screen that is touch sensitive, being able to play back video and music. But I’m only interested in high-quality audio playback, being able to have all my CDs in lossless FLAC format for optimal sound quality. So a 16x2 LCD with some buttons is plenty. I now have a working system (but not yet installed in my car.) here’s a description of how I’ve built it. Most of the installations I’ve seen the use of the audio out from the Raspberry Pi, but it’s only 11-bit and sounds like crap. I want to use an external DAC, and you can get that to work in XBMC, but only menu and music output, not films. There are some HDMI to audio converters, but I’ll instead use a quality USB DAC. http://youtu.be/wzmFZlpbBCQ ...

Flac, the best choice

Audio Engineering Pioneer John Meyer: Stop Chasing The Next Big Thing, And Go With Flac Instead — Tech News And Analysis: John Meyer may be making really expensive loudspeakers, but when it comes to high-end audio, the audio engineering pioneer prefers free. FLAC, the open source audio format developed by Grateful Dead fans to trade bootleg recordings, is “the perfect format” for music aficionados looking for higher-resolution audio, Meyer told me during a recent interview. And to him, any company pushing trying to make a buck with selling upsampled music is just out to sell snake oil. “It’s tricking people who don’t know enough about technology,” he said. ...

Raspberry Pi as a Squeezebox Logitech Server

I love my music playback setup that consists of a couple of Squeezebox V3 players in different rooms so I can listen to music in lossless format wherever I am in the apartment. With the iPeng HD app on my iPad, I have a nice interface for controlling the players with album art and other nice features. But the best part is that I can playback high resolution audio directly on my iPad using the Camera Kit USB adapter and an HRT HeadStreamer DAC portable USB headphone amplifier. But I wanted a small, cheap and eco-friendly server for hosting my music files and wondered if I could use the Raspberry Pi. And here’s my findings. ...

Adding a Kingwa clock to a Pioneer PD S-505

Here is the second part of how to improve the quality of an old CD player, the Pioneer PD S-505. You can find the first part here. In this section, I’m going to show you how to install a better, more stable clock circuit into your 505 to lower the jitter. This particular clock comes from Kingwa, that has a series of crystal oscillators for improving DVD players, CD players, and DACs. The price is reasonable. I’ve installed them in three different units and had zero problems, so the quality seems reasonable. Ok, so why install a new clock? Isn’t there one in there already? Yes, your right. But by using better parts like crystals with lower ppm and also design a very clean power supply to feed the clock, you can make your CD-player sound much better. And the reason is lower jitter. But what is jitter? There is plenty of excellent places to go read up on it. Here’s some. ...

DIY speakers

I want to have a couple of speakers in the beadroom, so I started to search the net. I found a very intresting DYI speaker project here (Swedish). So I ordered the speakers and can’t wait to get them. My skills in working with wood is very limited, but I may get some help from one of my friends, who is an expert wood carpenter. ...

Grisen skriker

You got to love the net. What ever you search for, you’ll find it. One of the best concert I even attended was the last concert with a Swedish punk band called Grisen Skriker (the pigs are screaming) back in 1979. And guess what, someone took pictures of the event. Naturally I did a vanity search of the pictures, but couldn’t find myself in the pictures. But I did find the lead singer of the band Ebba Grön, one of the ultimate Swedish punk bands. He probably learned a thing or two that night. It took me one hour just to make it from the door into the hall where they where playing. The band eventually took their clothes of, because the air conditioning broke down.
