The HiFi Hobbyist Podcast

The transmission line loudspeaker represents one of audio engineering’s most fascinating attempts to solve a fundamental acoustic problem. Engineers must produce deep, uncoloured low-frequency sound from an enclosure without letting the driver's rear wave interfere with the front wave.

This topic holds personal interest for me because I recently purchased a pair of PMC Prophecy 5 loudspeakers. The transmission line serves as a trademark design for PMC across both domestic hi-fi and professional audio.

In this first episode, we will look at the problem that the transmission line loudspeaker overcomes and examine how it compares to other solutions. In the next episode, we will explore how these speakers have developed over time. Afterwards, I will reflect on how the PMC Prophecy 5 speakers sound in my own system before opening a debate on the merits of transmission line designs.

This episode features traditional English folk songs arranged by the Hi-Fi Hobbyist with the help of Mureka AI software. The songs featured are: The Goose and Common; The Dalesman's Litany; The Oaks Pit Disaster; The Lancashire Lads and Spence Broughton.

We hope that you enjoy these episodes!

Welcome to The final episode in our mini-series about the production of vinyl records and other physical media music formats. It has been inspired by attending a talk by Miles Showell, a renowned audio engineer who reminded me that my Hi-Fi only sounds as good as the material as I play on it.

In this mini-series in the first episode, we considered how vinyl records are produced from the recording session to the production of the final record that we can play on our turntables. The following episode focused on specific aspects of production notably mastering of the recording in preparation for final production.

The third episode focused on the work of two of the great audio engineers associated with the mastering process, Steven Wilson and Miles Showell.

In this final episode, in order to conclude the series, we will generate a discussion comparing the work of these two artisans.

In recognition of Miles’ work on Finlandia, the music accompanying this episode is a recording of this suite that he didn’t work on, downloaded from the Internet Archive by the London Proms Symphony Orchestra, conducted by Charles Mackerras originally released on London Records – STS 15159, together with Two Melodies, Op. 63, No. 2 from the same recording.

In recent years, Samsung has emerged as a major player in the global hi-fi marketplace. This episode is the third in a series of podcasts that seek to understand how and why this has happened and what the implications are for Hi-Fi hobbyists. The Hi-Fi Hobbyist has a personal interest here, Mark Levinson, the manufacturer of my amplifier, is one of the brands acquired by Samsung.

In the first episode of the series, we considered the history of Samsung from a local company in Korea to major electronics conglomerate and their acquisition of Hi-Fi brands.

After this, we considered what this means for both Samsung and for Hi-Fi Hobbyists now and in the future.

This third episode is a generated discussion about the implications for their Hi-Fi brands, and their Hi-Fi hobbyist customers.

The music that accompanies this podcast is more from the 24 Caprices for Solo Violin written by Niccolò Paganini between 1802 and 1817.

Back in December, the Hi-Fi Hobbyist podcast took a first look at the use of valves and transistors in Hi-Fi components. Valves or strictly thermionic valves are the British terms for what U.S. Hi-Fi Hobbyists call vacuum tubes.

In this series of episodes, we are taking a deeper, more detailed look at the topic. In the first episode, we looked at the underlying scientific theory, and the theoretical implications for sound quality.

In last week's episode, we looked at examples of real-world amplifiers and considered why the reality is more complex than the basic science might suggest.

In this final episode, we have fed the data to two AI protagonists and prompted them to debate the merits of valves and transistors. This debate is conducted in American English, so unlike the previous two episodes, this debate sometimes uses the terminology of vacuum tubes alongside valves.

In this episode, the music accompanying the podcast is classical music supplied by classicals.de. It features the 1924 arrangement of Gershwin’s Rhapsody in Blue for two pianos. Rhapsody in Blue was originally written as a composition for solo piano and jazz band. It was commissioned by bandleader Paul Whiteman, the work combines elements of classical music with jazz-influenced effects and premiered in a concert titled "An Experiment in Modern Music" on February 12, 1924, in Aeolian Hall, New York City.

This recording has been made for CLASSICALS.DE and released in 2025 under a Creative Commons - Attribution-Non Commercial 4.0 International licence.

It has been chosen because pianos are often cited as a difficult instrument for Hi-Fi systems to reproduce.

Back in December, the Hi-Fi Hobbyist podcast took a first look at the use of valves and transistors in Hi-Fi components. Valves or strictly thermionic valves are the British terms for what U.S. Hi-Fi Hobbyists call vacuum tubes. We will use the term “valve” throughout these podcast episodes.

In this series of episodes, we are taking a deeper more detailed look at the topic. In last week’s episode, we looked at the underlying scientific theory, and the theoretical implications for sound quality.

In this week’s episode, we will start by looking at examples of real-world amplifiers and then consider why the reality is more complex than the basic science might suggest.

In the final episode, we will feed the data to two AI protagonists and let them debate the merits of valves and transistors.

In this episode, the music accompanying the podcast is music created by the Hi-Fi Hobbyist with the help of Mureka AI to evoke the rock and pop music from the 1970s and 1980s.

It starts with a largely acoustic track that borrows from the roots of rock and roll, before gradually moving on to different forms of rock, first southern rock, then the kind of smooth rock that characterised many American bands in the 1970s, before finishing with a good old British style rock track. This kind of music has traditionally been thought to be better reproduced by transistor amplifiers than valve amplifiers.

In this series of episodes, we will take the chance to take a deeper more detailed look at the topic. In this first episode we will look at the underlying scientific theory, and the theoretical implications for sound quality.

In the next we will start by looking at reviews of real-world amplifiers and then consider why the reality is more complex than the basic science might suggest.

In the final episode, we will feed the data to two AI protagonists and let them debate the merits of valves and transistors.

In this first episode, the music accompanying the podcast is Big Band swing music created by the Hi-Fi Hobbyist with the help of Mureka AI to evoke the era when valve amplifiers were the only technology available.

This podcast is the last in a series that seeks to explore the rise of Japanese Hi Fi, understand how this occurred, and to look at the lessons from history about the current rise of the Chinese Hi-Fi industry,

In this episode, we will consider the parallels between the growth of the Japanese Hi-Fi Industry of the twentieth century and the emergent Chinese industry of the 2020s.by prompting an AI discussion to focus specifically on these parallels.

The discussion is created by inputting the series of podcasts and their sources into Notebook LM and prompting a discussion on the parallels between the growth of the Japanese Hi-Fi Industry of the twentieth century and the emergent Chinese industry of the 2020s for an audience of Hi-Fi Hobbyists.

This week’s episode is accompanied by music created by the Hi-Fi hobbyist with the help of Mureka AI in the style of electro pop designed to create an atmosphere of modernity.

This podcast is the third in a series that seeks to explore the rise of Japanese Hi Fi, understand how this occurred, and to look at the lessons from history about the current rise of the Chinese Hi-Fi industry,

In this episode, we will tell the stories of the businesses that joined them after the Second World War and played a key role as Japanese Hi-Fi brands spread to the West in the 1960s, before considering the parallels between the growth of the Japanese Hi-Fi Industry of the twentieth century and the emergent Chinese industry of the 2020s.

The final episode we will return to this theme by prompting an AI discussion to focus specifically on these parallels

This week’s episode is accompanied by music created by the Hi-Fi hobbyist with the help of Mureka AI designed to reproduce the style of acoustic folk music that was popular in the UK in the 1960s and 1970s when Japanese brands emerged to dominate the mainstream Hi-Fi industry by offering value, reliability and modernity.

This podcast is the second in a series that seeks to explore the rise of Japanese Hi Fi, understand how this occurred, and to look at the lessons from history about the current rise of the Chinese Hi-Fi industry,

In this episode, we will focus on the life stories of the first Japanese Hi-Fi businesses that were created between the World Wars, although they only emerged in the West after the Second World War.

Next week, the third episode will tell the stories of the businesses that joined them after the Second World War and played a key role as Japanese Hi-Fi brands spread to the West in the 1960s, before considering the parallels between the growth of the Japanese Hi-Fi Industry of the twentieth century and the emergent Chinese industry of the 2020s.

In the final episode we will return to this theme by prompting an AI discussion to focus specifically on these parallels

This week’s episode is accompanied by music created by the Hi-Fi hobbyist with the help of Mureka AI, designed to reproduce big band music from the interwar era when the earliest Japanese Hi-Fi brands were established.

In the current era, much has been made of the rise of Chinese manufacturing companies within the Hi-Fi industry. However, they are not the first Asian country to rise from almost nothing to world domination in terms of the audio industry. After defeat in the Second World War, Japan’s industry was almost wiped out and yet by the 1970s it had achieved domination in the mainstream Hi-Fi industry in the UK and beyond.

This podcast is the first in a series that seeks to understand how this occurred, and to look at the lessons from history about the current rise of the Chinese Hi-Fi industry, which is seeing a dramatic rise in market share. Is history repeating itself or is there a different story this time? In the face of Japanese Hi-Fi overtaking the mainstream, British manufacturers moved up market and differentiated themselves by distinctiveness and appealing to the Hi-Fi hobbyists.

Will a similar approach enable them to stand up to new Chinese Hi-Fi brands, or in this age of digital audio, will Chinese R&D win the day?

In this episode, we will introduce the series by looking at the rise of the Japanese Hi-Fi industry and discussing some of the ideas and key products that established their Hi-Fi credentials.

In next week’s episode, we will consider the development of the first Japanese Hi-Fi brands, which emerged between the World Wars, but rose to prominence in the West in the 1970s and 80s,

In the third episode, we will tell the stories of the companies that emerged after the Second World War and ask if we can see parallels with the emergent Chinese Hi-Fi industry of the 2020s.

In the fourth and final episode, we will prompt an AI discussion to focus specifically on the parallels between the growth of the Japanese Hi-Fi Industry of the twentieth century and the emergent Chinese industry of the 2020s.

This week’s episode is accompanied by music created by the Hi-Fi hobbyist with the help of Mureka. AI designed to reproduce popular music from the 1970s, when Japanese brands took over the mainstream Hi-Fi industry by offering value, reliability and modernity.

In the previous two podcasts we have detailed 100 years of the BBCs contribution to audio and Hi-Fi in the UK across, engineering innovations, high quality radio broadcasting, talent nurturing, and loudspeaker designs.

This week we prompted an AI discussion to consider which of these contributions was the most valuable using Google’s Notebook application.

The music to accompany this week’s podcast was generated by the Hi-Fi Hobbyist with the help of Mureka AI software and celebrated piano ragtime which emerged in the 1920s alongside the BBC.

I hope you enjoy the discussion!

And when you have listened to the discussion, ask yourself which do you think are the BBC’s greatest contributions?

Where do you think British Hi-Fi would be without them?

And if you have enjoyed this discussion, why don’t you follow the Hi-Fi Hobbyist podcast wherever you get your podcasts to ensure you don’t miss future episodes?

In this podcast, the second of a miniseries of three, we shall discuss the BBC’s contribution in three specific areas: loudspeaker design, digital audio and nurturing audio engineering talent.
The music that accompanies this podcast once again reflects the BBC's long contribution to classical music.
The BBC retains ownership of most of the Proms concerts, so we feature a public domain recording of selections from Faure’s Requiem, a piece of music that I first heard performed at the Royal Albert Hall in 1982 as part of the BBC Proms season.
This recording is from 1962 and is sourced from Wikimedia Commons, featuring the Orchestre national de l'Opéra de Monte-Carlo with the Louis Frémaux Chorale, Philippe Caillard, and Bernard Kruysen.
This sound recording is out of copyright because it was published in the European Union more than 50 years ago, and the rights of its performers and producers have expired under European Directive 2006/116/EC.

In the first part of this podcast, we will consider the contribution of the BBC to audio engineering through its groundbreaking loudspeaker designs

The BBC (British Broadcasting Corporation) was founded on October 18, 1922, as the British Broadcasting Company by a group of wireless manufacturers. It was later established as a public corporation under a Royal Charter on January 1, 1927, which is when it officially became the British Broadcasting Corporation, as it is still known today.

Over the years, the BBC has made several significant contributions to the field of hi-fi audio. This podcast is the first of a series of three in which we will explore the contribution and influence of the BBC to British hi-fi and beyond.

The music that accompanies this podcast reflects the BBC's long contribution to classical music, especially through its annual Proms season broadcast from the Royal Albert Hall annually by the BBC since 1927. They had started in 1895 under Robert Newman and conductor Henry Wood.

Following Newman's death and financial struggles for the orchestra, the BBC took over the running and broadcasting of the concerts, initially from the Queens Hall.

In 1941, the Queen's Hall was destroyed by an incendiary bomb during the Blitz, forcing the Proms to move to its iconic current home, the Royal Albert Hall.

The BBC retains ownership of most of the Proms concerts, so we feature public domain versions of pieces of music associated with the Last night of the Proms from the musopen.org site, used under a CC BY-NC-ND 3.0 licence, together with historical performances from the Internet Archive in the Public domain.

This podcast provides an overview of some of the BBC historical contributions. The next episode will focus specifically on BBC innovations in loudspeakers and digital audio, and the third will be a generated discussion of both podcasts

In the first part of this podcast, we will consider the contribution of the BBC to audio engineering through its library of peer-reviewed engineering papers, which made a very significant contribution to transforming hi-fi from an art form guided by guesswork into a precise, repeatable science.

Welcome to the second of our anniversary special podcasts in the hi-fi hobbyist series.
Throughout the first year of the hi-fi hobbyist podcasts, we have explored the use of AI technology in a number of different ways. In most cases, the podcasts have alternated in style on a fortnightly cycle.
The first podcast in the cycle is based on human-authored content. AI is used to turn the words into audio content using a synthesised version of the Hi-Fi hobbyist's voice, as is the case here.
The accompanying music is either from public-domain historical sources, often the case when classical music is used, or from AI-generated music in other genres.
The second podcast in each pair has often taken the form of an AI-generated debate about the content of the previous week's podcast. This debate is carefully steered by the hifi hobbyist, but where there are flaws occasionally, these are left in, in the interests of transparency.
This anniversary special represents a partnership between the human hi-fi hobbyist and the technology. In the first part of this podcast, the hi-fi hobbyist lays out how AI has been used over the year. This is followed by an exposition of the ethics of using AI in the ways described. After this, the podcast concludes with an AI-generated debate about these same ethical issues.
The music to accompany this podcast is generated using Mureka AI software and is in the style of piano ragtime from the 1920s

Welcome to the first of two special Hi-Fi hobbyist podcasts that celebrate our first anniversary.
The first sets out to reflect how the global trends and issues discussed in the podcast have impacted my own experiences with Hi-Fi at home, and influenced my buying choices.
Discussions of my own personal experience with Hi-Fi are generally dealt with in the shorter opinion pieces that you will find on the Hi-Fi hobbyist.net website.
However, for this anniversary special podcast, we will consider the elements within my main Hi-Fi system, which I refer to as my indulgent system, and reflect on how my buying choices are linked to the themes that I have explored over the last year of this podcast.
Only one of those components was produced by a manufacturer owned by one of my Hi-Fi heroes, and therefore, it seems appropriate to start with a discussion of my turntable, the Linn LP12, the product that launched the career of Ivor Tiefenbrun of Linn products.
With his well-known philosophy of source first, I hope he would agree!
The music accompanying this podcast was developed especially for it using Mureka AI software. It represents what AI thinks a baroque string quartet should sound like.

I'll let you decide if you agree!
