The HiFi Hobbyist Podcast

This is the second in an occasional series of podcasts devoted to some of my Hi-Fi heroes. This podcast is dedicated to Gilbert Briggs, founder of Wharfedale. These days, Wharfedale is owned by the International Audio Group and like QUAD, many of its products form part of the current fashion for retro products. Gilbert Briggs as well as being a great audio engineer was a big influence in popularising Hi-Fi as a hobby in the early days of the industry Gilbert Briggs was a proud Yorkshireman, so we have created a range of brass band music to accompany this podcast, using the Mureka AI software to create music in the style of the many colliery bands that were created in the county. Unfortunately, once I had done my research, it turns out that he was a huge fan of the piano, so perhaps that would have been more appropriate.

This week’s podcast features a debate between AI protagonists about one of my Hi-Fi heroes, Peter Walker, founder of QUAD. Peter Walker is responsible for a range of major innovations in audio equipment design. In this week’s debate, the protagonists consider the relative merits of Walker’s contributions, specifically whether his contributions to electrostatic loudspeakers outweigh the contribution of his various radical amplifier circuit designs. As Peter Walker was a keen musician as well as engineer, who favoured classical music, we have chosen more from Handel’s Water Music to accompany this podcast, performed by The Jean-Francois Paillard Chamber Orchestra, in a recording from 1961, available from the Internet Archive under a Usage Attribution-NonCommercial-No Derivative Works 3.0 Creative Commons Licence.

This is the second part of the Hi-Fi Hobbyist Podcast on AI and Music. In this part we present the second side of the virtual album “Journeys”. Side 2 is made up of songs based upon real-life journeys undertaken by ancestors of the HiFi Hobbyist, or other people known to him. These journeys were often undertaken willingly in search of new opportunities and generally have positive outcomes. The music reflects the more positive stories on side 2 of the virtual vinyl album. Following the music, there is a discussion of the issues around AI and music to conclude the podcast. If you enjoy the music, please access the full release with lyrics and images at the main Hi-Fi hobbyist website

In a previous podcast, we looked at Chi-Fi, Chinese-manufactured Hi-Fi, which is gaining increasing recognition in the international Hi-Fi market. In this podcast, we will look in more detail at how this industry has developed from a low-cost manufacturing centre to an innovation and R&D hub, and how Chinese brands are now building products based on their own innovations that can match or outperform traditional rivals from the West. In the first part, we look at the historical development of the industry before moving on to policy and economic drivers. After that, we will consider examples of technological innovations originating in China and the Hi-Fi products developed from them. The podcast concludes by considering potential future directions and trends. The accompanying music is by Frédéric Sylvestre and hosted at pixabay.com, and is used under a Pixabay content licence.

Recent opinion pieces on the HiFi Hobbyist website have reported on differing views from online commentators on the importance of room acoustics and room treatments. In this podcast, we will look in more detail at the underlying scientific theory and seek our own conclusions on the topic. Part 1 of the podcast outlines the basic acoustics theory, Part 2 looks at the implications of the Schroder frequency and the need to handle upper and lower frequencies differently and then Part 3 looks at treatments designed to alleviate problems caused by reflections and reverberations, before a final conclusion. The accompanying music consists of two concertos in the Baroque style, created by the HiFi Hobbyist with the help of Mureka software.

For me, the 1970s were a golden age of the double live album. Of course, these were the days of vinyl, so we’re talking about four sides, giving a total playing time of up to about 90 minutes. Speaking personally, this was how I got to know some of my favourite bands of this era. In this podcast, I will seek to identify my five favourite live albums from the period and discover how they were recorded. What are your favourite live albums from the era? What memories do they evoke? I hope you enjoy the podcast

This week’s podcast is the third of a four-week cycle. This week will review recordings of Beethoven’s nine symphonies from the last one hundred years. This will be followed next week by letting our AI protagonists discuss the most significant recordings of Beethoven’s symphonies. The podcasts are all accompanied by extracts from the Symphonies. This week’s recordings of the Eroica Symphony are performed by The Czech National Symphony Orchestra and published by the Musopen Kickstarter Project under a Creative Commons PDM 1.0 Licence and hosted at classicals.deI hope you enjoy this week’s podcast, and if you do, please come back next week for the last podcast in the cycle, or if you have not done so, catch up with the previous podcasts.

This week’s podcast is the first of a four-week cycle. This week we will review Beethoven’s nine symphonies and choose a top five. This will be followed next week by letting our AI protagonists discuss the symphonies and the Hi-Fi Hobbyists ranking. After that, the following week’s podcast will consider some of the greatest recordings of Beethoven’s 9 Symphonies cycles, both from a musical and audio perspective, as befits a Hi-fi hobbyist podcast. The four-week cycle will conclude with an AI discussion of the different recordings. The podcasts are all accompanied by extracts from the Symphonies. This week’s recordings are performed by performed by The Fulda Symphonic Orchestra, who were recorded live on March 10, 2002 at the Grosser Saal der Orangerie.

I hope you enjoy this week’s podcast and if you do, please come back in future weeks for the later podcasts.

A few weeks ago, the main Hi-Fi Hobbyist looked at the emergence of Chi-Fi. Chi-Fi describes an industry phenomenon where independent Chinese brands deliver high-performance audio equipment at disruptive prices. It marks a shift from OEM manufacturing of Western designs to the emergence of Chinese designed kit offered by Chinese brands and sold on global platforms such as Amazon. This podcast looks in more detail at how it has developed, and the implications for Hi-Fi Hobbyists and Hi-Fi manufacturers in the West.

A few weeks ago, we looked at the the difference between valves and solid-state components such as transistors or integrated circuits in hi-fi amplifiers. One of the issues that emerged from that podcast was the question of amplifier topology or class. It appeared from the research undertaken that the amplifier topology could have as much impact on the ultimate sound as the nature of the devices doing the amplification. In this podcast, we will consider the most common amplifier classes, the characteristics of the sound with which they are associated and some examples of highly regarded amplifiers within each class. The very fact that there are highly regarded amplifiers in each class suggests that no one class is best, but rather each has its own characteristics, and in conjunction with the loudspeakers used will generate its own particular sound quality.

Jethro Tull have been producing music since 1968, and therefore selecting 5 favourite Jethro Tull albums for this podcast is a difficult task. This week's podcast is the Hifi Hobbyist's attempt to select a Top Five Jethro Tull albums. Only five in the list in order to try to explore the merits of each title in some detai,l particularly with reference to the sound quality of each album. The Jethro Tull catalogue has been well served by a series of remixes by Steve Wilson, often on the 40th anniversary of the original release. Many of Jethro Tull’s early albums, in particula,r push the boundaries of what was then technically possible, and this perhaps explains why the quality of some of the original releases was less than ideal. In selecting my favourite 5 albums, I have taken into account that some of the Jethro Tull albums can be seen as companion pieces. Thus, a Passion Play and a Thick as a Brick both represent concept albums and share a common tongue-in-cheek approach. Heavy Horses and Songs from the Wood represent a more rural and folksy approach to music. Stormwatch whilst musically similar to Heavy Horses and Songs from the Wood looks forward lyrically to the more apocalyptic themes of A. Crest of a Knave and Rock Island represent a harder rock sound, whilst Minstrel in the Gallery and Too old to Rock'n'Roll, Too Young to Die can be seen as concept albums based around relatively short individual tracks. In order to reduce my options, I elected to set the criteria that no two albums that represent companion pieces could appear in my top five. The selection is based on musical and lyrical quality, rather than the sound quality of the original releases, but as this is a hifi hobbyist podcast, we will certainly discuss sound quality, especially in relation to the Steve Wilson remixes where available. As usual, we cannot use Tull’s music for copyright reasons, so the music featured is a version of Bourrée in E minor from J.S. Bach's Lute Suite in E minor, BWV 996. This is the piece that inspired Jethro Tull’s famous Bourrée track when Ian Anderson heard Martin Barre play it on his guitar. Our version is by Jakob Lindberg, and the recording is in the public domain.

Happy Christmas from the HiFi Hobbyist! This week’s podcast considers Handel's Messiah, which has become a staple at Christmas. We shall consider its origins, its impact, and the HiFi Hobbyists favourite recordings The selections of Messiah that accompany the podcast are supplied from Wikimedia Commons.

This week’s podcast which considers the relative merits of valve and solid-state circuitry in high-fidelity audio amplification. We use the term “solid state’ because the discrete transistors of early designs have now largely been superseded by integrated circuits incorporating many transistors Transistors largely replaced valves in the 1960s, but have retained a niche market in high-end, and also some budget enthusiast products, and we will try to understand why. As valve amplification is often associated with fans of acoustic music, this week’s music is a piece of acoustic jazz entitled Fast Jazz by WaveMaster and used under a Pixabay licence. I hope that you enjoy the podcast!
