Alpha Audio’s Hifi Hour!

We talk with Joakim Juhl from Oephi. We talk about system balance, cable integration and a bit about some other topics like capacitance, PRaT and how to start with creating balance.

Mafico is op bezoek bij Hifive Studio in Zeewolde. Garmt legt uit hoe DS Audio cartridges werken en wat de voordelen zijn van het systeem. 

Power is power. Right? That’s what many people believe. As long as 230 volts comes out of the wall socket, it doesn’t matter how you bring it to your amplifier. Right? But anyone who digs a little deeper – or better: truly listens – discovers that the story is much more complex. A power cable is not a neutral pipe that simply carries current. It’s an active link that can audibly influence timing, dynamics, and calmness in a system. We talk with Joakim Juhl from OePhi-Cables, Denmark. More information: www.alpha-audio.net.

We have another interesting talk with Joakim Juhl; founder and owner of OePhi Cable (Denmark). This time we talk about digital cables. Are there actually digital cables? We are about to find out!  

Alfred Vassilkov came to visit the Netherlands. So when he was at Hifi Studio Wilbert in Utrecht, we took the opportunity to schuedule an interview with him. He was kind enough to sit down with us for over an hour. We asked him about his youth, his passion for music, electronics and of course his designs.

We houden een interview met Mark Otten: coach, dj en docent aan onder meer het Haarlems Conservatorium. We praten over zijn drijfveren, achtergrond, carrière en bijzondere leerlingen. We have an interview with Mark Otten: coach, DJ and teacher at, among others, the Haarlem Conservatoire. We talk about his motives, background, career and special students.

At the first edition of the Noir & Blanc Hifi Show in Brussels, we did a presentation about Streaming Audio Networks. We explained very shortly how networks work, the different media you can use to build a network and how to tweak it. And yes: we talked about the importance of decent equipment. Incluiding measurements to prove it :-).

Van den Hul zelf vertelt over zijn leven, akoestiek, kabels (en de materialen) en natuurlijk: vinyl. Hoe is hij tot zulke prachtige elementen gekomen? Waarom klinken kabels anders? En wat heeft hem gevormd tot wie hij nu is? Dit is een bijzonder interessante - en leuke, humoristische - presentatie om te zien. Mede omdat het anders dan anders is...!

We had a nice talk with Grant Samuelsen from Shunyata Research. We talk about how the company works, how they design their equipment ánd about an interesting new product: the Altaira. A grounding system that should improve the musical reproduction of practically any system. As a bonus we check out the Gemini: a small filter with also a grounding system.

We have a very nice interview with Sven Boenicke for Boenicke Audio in Switzerland. We talk about why he started the audio company, why his products are special and what we can expect in the future. The interview was done at Hifi Studio Wilbert in Utrecht, Netherlands. We thank them for the invitation and we thank Sven Boenicke for taking the time to talk to us.

We have a very interesting talk with Paul Graham and Derek Hughes about the Graham Audio speaker line-up ánd the history of the BBC monitor speakers.

We have another interesting talk about music with Ole from System Audio. This time we talk about live music and Dolby Atmos for music. How does that actually work? And what about surround sound with live concerts? And DSP's...? 

It is always an interesting topic: to go active or to go passive... Well: in case of speakers. Both have advantages. And of course: disadvantages. I talk to Ole to go a little bit more in depth. 

We have an in depth talk with Joakim Juhl from OePhi cables. We talk about... well: cables! We are curious about his design philosophy and view on measuring cables. 

Hifi gear - including speakers - get smaller every year. But how small can we actually go? We talk with Ole from System Audio about making stuff smaller and smaller... 

We have an interesting talk with Steven Samaan. He is an absolute DSP Wizzard. We want to know more about a new service Stassen in Limburg is offering: you can buy a very advanced DSP for your hifi-system and Steven will come to give it a complete, custom tune to your room and taste!

We sit down with Ole from System audio to talk about measurements in the Hifi World. What can we actually measure? And how about just listening to gear? What is actually more usefull?

We have a nice talk with Peter Van Willenswaard; the developer of the 'magical' PW1; Grimm's interpretation of a phono pre-amp. What makes it so special? Why does it sound the way it does? We asked Peter and of course played some music!

We have another talk with Ole from System Audio. This time we talk about music from the 90's. What makes this era so special? Be warned... a lot of memories come up! 

We have a long talk with Guido Tent and Eelco Grimm. We talk about the early days, the people behind Grimm, teaching, their products and of course music. 

We have another great talk with Ole from System Audio. We talk about some psychology around our hobby... How do we actually experience hi-fi? 

We talk to Eelco Grimm and Guido Tent about the Grimm MU2 streamer, pre-amp, dac, Roon Core. We discussed the digital part in the first episode. Now it is time for the analog part!

We talk with Eelco Grimm and Guido Tent about the beautiful Grimm MU2 streamer - pre-amp - dac - Roon Core. We start out with the digital part of the player. What makes it so special?
