The Lefson resistor review has just gone live at Positive Feedback! You can read the review here. As always, thanks for stopping by, and may the tone be with you!

It has been a busy audio weekend, and I'm trying to get caught back up after Jeff's Place going down due to the hacking event last week. The good news is that you've encouraged me to keep going with Jeff's Place for the foreseeable future. I was pretty discouraged after the hacking event, but with all... Read More »

My Dad went through a sudden decline in his health after a serious fall about three years ago, and was not able to go home again afterwards. Our family is spread out about as far as it is possible to be while still living in the USA, and with no family local to where Mom... Read More »

Thank you! Thanks to all of you who have encouraged me with help after the hacking incident that took down Jeff's Place a week ago, I truly appreciate all the kind words, good advice, and your offers to help with donations! Thank you so much, you are awesome! Friends of Jeff's Place I want to give special... Read More »

I'm hard at work this weekend writing up the Lefson resistor review for Positive Feedback.  I hope to get the review all finished up and published in the next week or two. Here's a little sneak peek until then! Enjoy! Lefson: French High-End Analog Audio Devices - The Lefson Resistor By Jeff Day I have been... Read More »

I've got some more information for you on the upcoming Duelund DCA12GA tinned-copper tone-wire! In the photo above you can see the raw tinned-copper wire used in the DCA12GA tinned-copper tone-wire. The new DCA12GA will use 65 strands of 0.25mm tinned-copper wires versus the 26 strands of 0.25mm tinned-copper strands used in the DCA16GA. Frederik told... Read More »

I don't know how many of you stopped by Jeff's Place on April 5th to do a little reading, but depending on when you stopped by, you might have noticed that nothing came up but a white screen. That's because somebody decided it would be fun to hack Jeff's Place and destroy it. Apparently, somebody (or a malware... Read More »

I've been wanting to try the Duelund DCA20GA tinned-copper tone-wire as a shielded interconnect between my Intact Audio SUT and vintage McIntosh MX110Z tuner-preamplifier for a while now. As most of you know, response to the Duelund DCA20GA as interconnects has been extremely positive, and I really like the ones I made up a lot (below).... Read More »

I get really excited about vacuum tubes! When Sue and Richard at Sophia Electric contacted me about doing an article about their new Sophia Electric™ EL34-ST vacuum tubes I was quite intrigued. I don't know what it is, but every time I see a vacuum tube with the 'ST' style of glass bulb shape I just swoon, I... Read More »

This morning I'm writing the introductory part of the Lefson resistor article for Positive Feedback while listening to music, with plans to write up listening impressions on how the Lefson resistors performed in my Altec A7 Voice of the Theatre project crossovers tomorrow, and hopefully write a summary & conclusions section before the end of the weekend. I hope... Read More »

Yesterday after I rewired the high-frequency circuits of my Westminster's Duelund CAST crossovers with the Duelund DCA20GA tinned-copper tone wire, I was so excited by the results that I decided I wanted to rewire the low-frequency circuits too. It was spur of the moment decision to rewire my crossovers, so I didn't precondition any of the... Read More »

I'll start with the other stuff. I traveled to Washington, D.C. this last week, where we received a Secretarial Award for our US Belle II High Energy Physics project at KEK, the particle physics laboratory in Japan. A little bit of background: The Belle II experiment’s global collaboration involves more than 600 members, 65 institutes,... Read More »

It's always a treat to hear from Jim Smith, and as many of you know, I have the greatest respect for Jim and his many contributions to the worlds of music & audio, and am just generally a big fan of Jim's! Jim's demos at CES over the years have always been impressive, and you have... Read More »

This is the fifth post I've written about the Lefson resistors that are manufactured by Xavier Lefebvre in Wormhout, France. Let me summarize what I've written about Lefson until now: In my first post I introduced the three product lines of carbon/silver audio resistors that are available from Lefson, the Premium, the Supra, and Ultra. The Premium resistor from Lefson is... Read More »

Happy Weekend! I was really glad to see this weekend arrive, as during the week I had come down with a nasty cold and had been only working half days trying to get feeling better. Ugh. I don't know if it's a coincidence or not, but right after co-worker Melanie gave me some Cold-EEZE lozenges to try... Read More »

In Parts 1 & 2 of my Today's Fresh Catch series of posts about the new Acoustic Revive AC power supply components, I introduced the RTP-6 Absolute NCF six-outlet AC power distributor and the Power Reference TripleC NCF AC power cords, respectively, which you could rightly consider to be the exotic bespoke Aston Martin DB4 GT Continuation versions of the AC power supply world....

It's always fun to get out and about for an adventure, particularly when it includes music! Friend and fellow Westminster owner, Leo, and I were in Seattle yesterday for a brief visit and stopped in at Jazz Alley to catch the Bob James Quartet's performance, and it was awesome! You might remember that multi-Grammy winning... Read More »

I've mentioned before that I get pretty excited whenever I hear from Yoshi-san & Elia-san (father & son) of the MuSon Project in Osaka, Japan, who export Japanese audio exotica to The World, because it means that something exciting is about to happen audio-wise! Yoshi-san told me that he had a new phonograph cartridge that he... Read More »

There's so many new readers at Jeff's Place these days, that I thought it would be a nice idea to go over the purpose of my Jeff's Place audio blog again, describe where it fits in my spectrum for audio reviewing and reportage, discuss my reviewing methodology, my biases & preferences, and give you a 'master list' of...

It's always exciting to start a new audio adventure with vintage hi-fi electronics, and I'm particularly excited about my new vintage audio adventure with the vintage monaural McIntosh C-8 'Professional Audio Compensators' as McIntosh called them, or phono preamplifiers, as the rest of us call them. I read where the original principals at McIntosh thought... Read More »

As I posted earlier, I'm really looking forward to trying friend Yazaki-san's ideas for modifying my vintage McIntosh MC30 monaural amplifiers. It's always fun doing audio adventures with Yazaki-san, as his insight, knowledge, and experience have really changed the way I think about audio performance, and for voicing my system at the 'DNA level' using resistors,...

I introduced you to the Acoustic Revive RPT-6 Absolute in Part 1 of this post, which allows up to six AC power cords to be plugged into it, which is enough to serve as a central point to coordinate all the AC power cords for my entire system, with two extra outlets to allow for a pair...

As I mentioned in Part 1 of this post, there’s so many good audio things happening right now I thought I’d better write a quick survey for you about all the things that are in play, culminating with my ‘roadmap’ for writing about it all in the near future. ¸¸.•*¨*•♫♪¸¸.•*¨*•♫♪¸¸.•*¨*•♫♪ I introduced Xavier Lefebvre and Lefson Analog...
