Over the last couple of weekends I have made quite a bit of progress on the Duelund-WRSE Project. Last weekend my buddy Dave and I worked on the final chassis design for the outboard Duelund crossovers, and we went into Dave's woodworking shop to get the chassis started and made a lot of progress. As I... Read More »

Thanks to everyone for the well wishes on my 1oth anniversary as an audio writer! I appreciate Mike's encouragement to write a little more about recordings too, because that's something I always intend to do, but the software scene seems to get away from me when I'm trying to keep up with the hardware scene!...

It's no secret that I really like the New Valve Order SPA-II phono equalizer and have been using it as my reference, and as I posted earlier, I have the new entry level SPA One in for review (below), and from what I'm hearing it promises to be something special as well. Panicos told me... Read More »

Today I added a Review Archives page to Jeff's Place in the top navigation bar as a resource for finding different articles I had written over the years. As I was putting together a list of links for the article archive I realized that it’s my 10 Year Anniversary writing about Hi-Fi! I started writing about Hi-Fi... Read More »

I just wanted to let you know about something handy I've run across: Peavey color coded microphone ID tape. The Peavey color coded microphone ID tape includes eight rolls of tape in different colors: yellow, blue, red, orange, brown, green, white, and silver. While the intention of the Peavey tape is to identify various stage... Read More »

I've been listening to the breadboarded versions of the Duelund crossovers on the Westminster Royal SE's this week, in the evenings after I got home from the office, and man, what a revelation! I decided to take today off and get some more work done on Duelund-WRSE Project.  Before getting started on what I need to... Read More »

If you've been following along you know that Siedy (photo below) has been a true inspiration for yours truly. If it wasn't for Siedy I would never have had the opportunity to try the superb ASR electronics that are hand-crafted by Friedrich Schaefer in Herborn, Germany. It was a wonderful experience writing about the ASR electronics... Read More »

I just finished up installing the other Duelund crossover on the right Westminster Royal SE, so now I have a stereo pair up and running. Not bad progress for a weekends worth of work! I was able to improve the layout of the right channel pair of Duelund crossovers and make it quite a bit more... Read More »

I was chatting with Frederik Carøe in Denmark this morning by email while waking up with some nice hot coffee (medium roasted Kenya beans). I wanted to give Frederik an update on how things are going with the Duelund-WRSE Project, and ask Frederick for any suggestions he might have on improvements and such.   I... Read More »

Stephaen sent an early morning email: "I'm going to stop at the El Fat Cat Grill taco truck and get us lunch, and I'll meet you and Pete at your place at noon." While the El Fat Cat Grill is actually a taco truck, referring to it as 'taco truck' is like referring to the... Read More »

In the Duelund-WRSE Crossover Project we are using the Duelund Coherent Audio Silver / Carbon resistors exclusively in the circuits (seen on the far right in the photo below). Resistors are inherently simple electrical devices that are used to control the flow of current in a crossover circuit by providing a constant resistance that does... Read More »

I'm up early this morning drinking coffee and listening to the Beatles' Rubber soul LP from the new box set through the Sophia Electric 91-03 300B integrated amplifier. Particularly considering the 91-03 hasn't even been playing for an hour, its sounding really good. Very natural, sweet, and musical. Today Pete Riggle & Stephaen Harrell (6Moons) are coming over to... Read More »

As most of you know, the Sophia Electric 91-01 300B mono amplifiers that I reviewed for Positive Feedback Online back in January of 2011 reignited my interest in SET amplification, because they made incredibly beautiful music with my Tannoy Westminster Royal Special Edition loudspeakers. Richard Wugang, the President of Sophia Electric, just sent me a... Read More »

Today's Fresh Catch is the new Duelund Coherent Audio CAST Mylar Capacitor. For those of you who have been following the developments of the Duelund-WRSE Project, where we are building custom outboard crossovers for the Tannoy Westminster Royal SE loudspeakers using the state-of-art Duelund Coherent Audio CAST components, you know that Frederik Carøe created a...

I can't think of a better way to spend a Saturday than eating wood-fired pizza, drinking some nice Italian & Argentinian wines, and laughing & talking with Pete Riggle and Stephaen Harrell while breadboarding the Duelund-WRSE crossovers. We started with a full set of the Duelund CAST components for the crossover. (seen below sitting on... Read More »

The ASR Basis Exclusive phono equalizer review is now live at Positive Feedback Online here. Here's a few snippets from the review: "Like the Emitter II amplifier, the ASR Basis Exclusive phono equalizer is a remarkable product that will delight those vinyl lovers lucky enough to own one." "The Basis Exclusive consists of two chassis... Read More »

Pambos just sent me an email with an excellent suggestion about posting photos of peoples' Westminster Royal or Canterbury loudspeakers in their listening rooms, based on the interactions we've had for upgrading the crossovers on those two speakers. We've got a lot of Tannoy owners that drop by, and I didn't want to exclude anyone,... Read More »

In my last post I described all of the attention to detail that goes into producing the hand-made & labor intensive Duelund CAST capacitors, and in this post I want to tell you about the Duelund CAST Air Core Inductor that we will be using in the Duelund-Westminster Project as shown in positions L1 and L2 below. An inductor... Read More »

Many of you who read Jeff's Place consider the Duelund Coherent Audio CAST capacitors to be the best capacitors in the world for audio applications, so I thought it would be interesting to learn about them in a little more detail. I asked Frederik Carøe (founder of Duelund Coherent Audio) if he would tell us... Read More »

I know that a number of you have been inquiring about upgrading your Tannoy Canterbury SE loudspeakers with Duelund components, so I thought I'd post this note from Pambos: "Today I visited my customer with the inboard upgraded Canterbury crossovers. I took some pictures. Are not the best pictures because I didn't remove the crossovers and... Read More »

A number of you who have been following the Duelund-WRSE Project have been asking about if it would be possible to arrange for a group purchase of the Duelund Coherent Audio components at a discounted price to use for crossover upgrades for your Tannoy loudspeakers. Frederik Carøe (founder of Duelund Coherent Audio) became aware of... Read More »

The energy & excitement behind the Duelund-WRSE Project is really ramping up and I'm thrilled about all of you who are joining in to do your own Tannoy loudspeakers project at the same time! I will document every step of the project here at Jeff's Place so everyone will have real-time information flow, and I... Read More »

I got a message from FedEx this morning notifying me the Duelund Coherent Audio components from Frederik Carøe - the founder of Duelund Coherent Audio - for the Duelund / Westminster Royal Special Edition Project had arrived and were being held for pickup. I had a little break from meetings in the office so I went straight... Read More »
