Crazy comparison! The Pass Labs XA25 Stereo Amplifier and the Vintage McIntosh MC30 Monaural amplifiers!

It was a really enjoyable Friday this week, with a splendid visit from Paul James, who came all the way from Australia to visit Jeff's Place. Paul is a super nice guy, as well as a really knowledgable audio guy who likes to build valve preamps &  amplifiers, and loudspeakers from scratch, and it was... Read More »

Jeff checking in ... the Duelund-Altec Project, musical chairs with Pass Labs & First Watt stereo amplifiers, and enjoying the company of friends!

The Duelund-Altec Project is really something special, a lot of fun, and it's definitely not your typical audio project or review, but rather is intended to be more of a "dream" article that is decidedly outside of the usual audio mainstream, one that involves a story about the marriage of the historically important vintage Altec...

First Listen: The new Duelund plastic-free RCA's & DCA16GA interconnects!

I told you about the new pre-assembled Duelund Coherent Audio DCA16GA tinned-copper interconnects in my last "Today's Fresh Catch" post (HERE). The new pre-assembled Duelund DCA16GA interconnects are notable for a couple of reasons, the first being that you can buy them pre-assembled from Duelund instead of having to build them yourself as in the...

Today's Fresh Catch: A Duelund Coherent Audio world's first just announced!

This morning I got an email from Frederik about the pending delivery of the new Duelund Coherent Audio plastic-free RCA's that he thinks makes for a nice improvement in performance over the already superb Duelund RCA's that I've been terminating my interconnects with. In his classic short teaser style, Frederik said, "It’s a world’s first... Read More »

Duelund-Altec Project Update: From Breadboard to Phase I Crossovers!

It's been a nice couple of weeks here at Jeff's Place, first with the solid walnut "cutting board" plinths arriving for the Duelund CAST tinned-copper crossovers, and my buddy David helping me getting them ready to mount the Duelund CAST tinned-copper components on them, but the real treat this last week was a visit from my...

Jeff checking in ... the Pass Labs XA25 amplifier and the Duelund-Altec Project!

I mentioned in my last "Today's Fresh Catch" post (HERE) that the Pass Labs XA 25 power amplifier (below) had arrived here at Jeff's Place for me to listen to, blog about, and write a feature article about for you at Positive Feedback. After hearing Nelson's First Watt SIT-III power amplifier (below) and how impressive... Read More »

Update: The Duelund-Altec Project

It's time for another update on the Duelund-Altec Project. In my most recent updates of the Duelund-Altec Project I discussed the overall project context HERE, the selection of speaker cables for the most complementary voicing HERE, and I wrote a just-for-fun post about the musicality magic of vintage Altec's HERE.  I've never been enamored of...

Duelund 600V DCA12GA, DCA16GA, or DCA12GA on the "Stokowski" Altec's as speaker cables? Update!

I've really been enjoying the Duelund-Altec Project, and I fully admit that I am in awe of the performance I'm hearing from the exotic Duelund CAST tinned-copper crossovers (Hiraga-style circuit) with my vintage one-off "Stokowski" Altec loudspeakers.  The live-like musicality, sonics, and intense emotional impact the Duelund CAST tinned-copper crossovers combined with the "Stokowski" Altec's are...

The Duelund-Altec Project: First listen to the completed crossovers!

Yesterday when I signed off, I had just finished connecting the Duelund CAST tinned-copper crossover in the right "Stokowski" Altec loudspeaker, and did a little listening to compare it to the Altec N-500-D crossover in the left loudspeaker. The "Stokowski" Altec's actually sounded really good with their original Altec N-500-D crossovers, so I wasn't sure... Read More »

An awesome vintage system for ~$10K USD! now + postscript

An old high-school buddy that I reconnected with recently, Mark, asked me for a recommendation for a HiFi system for $10K or under. Mark is actually the person who introduced me to enthusiast audio way back when we were in high-school together, but he's been out of enthusiast audio for quite a long while. As... Read More »

Duelund DCA wiring fun with Tannoy's and Altec's! Update.

As I've mentioned in previous posts, I've been having fun trying different wiring schemes with my Tannoy Westminster Royal SE loudspeakers and their Duelund CAST crossovers, as well as my vintage Altec based systems. Tannoy Westminster Royal SE based system: My living room music system is composed of Tannoy Westminster Royal SE loudspeakers with outboard... Read More »

Vintage Altec 832A Corona's as a bedroom system!

I went a bit wild today and decided to rearrange all my bedroom furniture so I could set up the new-to-me vintage Altec Corona loudspeakers as my bedroom system. The speakers look small in the photo above because of the size of the room, but they're really 3.5 feet tall and 3 feet wide, so... Read More »

A look back at my year in reviewing, and choosing the Positive Feedback 2017 Writers Choice Award winners!

The Editors of Positive Feedback, Mr. Dave Clark and Dr. David Robinson, just sent out a message calling for the writers to turn in their three Writers Choice Awards for 2017. Every year Dave and David's message results in my going back and reflecting on my year in audio, the products I've written about for Positive Feedback, and...

A Shielded Duelund DCA26GA Interconnect for Sunday!

This morning I built a 1-meter shielded Duelund DCA26GA tinned-copper interconnect (shield connected at source end) to connect the 2-Ohm version of the Arai Lab MT-1 SUT that I am currently reviewing for Positive Feedback to my vintage MX110Z preamplifier's phono stage. I now have shielded versions of the DCA16GA, DCA20GA, and DCA26GA tinned-copper interconnects... Read More »

Jeff checking in ... Duelund DCA, FryBaby2, Sophia Electric, and more!

Using the Hagerman Audio Labs FryBaby2 in voltage-only mode has revealed itself to be a powerful voicing tool for the Duelund DCA line of tinned-copper cables. Every single time I've used the FryBaby2 on the Duelund cables it has been a smashing success. In its voltage-only conditioning mode the FB2 has worked wonders on my... Read More »

Sneak Preview of my upcoming article for Positive Feedback: An Adventure in the Art of Tone with the Duelund Coherent Audio DCA Series of Tinned-Copper Cables, Part 1 - Update - now live at PF!

I've been writing my bum off the last few weeks working on a survey article of the Duelund DCA line of tinned-copper cables for Positive Feedback. I'll be submitting the article to Positive Feedback Editors David and Dave for their consideration sometime today, so you should expect to see it published before too long. Until... Read More »

A little bit of voltage conditioning for my unshielded Duelund DCA16GA interconnects!

I thought I'd provide you another update on my voltage-only conditioning results with the Hagerman Audio Labs FryBaby2, this time with a pair of unshielded Duelund DCA16GA interconnects. I put my unshielded DCA16GA interconnects on the FryBaby2 for 24 hours of voltage-only conditioning, and tonight put them in the system for a little listen. I... Read More »

Today's Fresh Catch: Hagerman Audio Labs FryBaby2 Compact Burn-In Generator

I was particularly intrigued by Bill's comment on the post Jim Smith Checking In: “Unexpected results from the Duelund DCA20GA Interconnects”: Jeff, Not really sure where to post this. I think I discovered something with the Duelund Tin wire. If its running thin and sometimes cooking them can do this. But I noticed on two different... Read More »

Jeff checking in ...

It sure was nice getting together with Andy, Pete, and Ron, last weekend to listen to music, talk about hifi, and just have a fun ol' time! I could use a little more musical & audio fellowship in my life! Alas, it's been particularly busy of late, both on the day job, and in my... Read More »

Jeff checking in ... I'm back!

I just got back home from two weeks of travel with little to no internet & email access most of the time, so I'm way behind on addressing comments & writing blog posts, and I'm playing tag with jet lag. I did get a chance to listen to a variety of live music performances of... Read More »

Which is better? The Duelund DCA16GA, DCA20GA, or the Silver/Silk Interconnects?

Which is better? The Duelund DCA16GA, Duelund DCA20GA, or the Duelund Silver/Silk interconnects? The conclusion that I've come to is that they all are better, depending upon the application I'm using them for. For example, I had been using a set of nude Duelund DCA16GA interconnects to connect my vintage McIntosh MX110Z tuner-preamplifier and vintage McIntosh... Read More »
