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 »

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 »

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,...

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...

What do you do when you wake up at 2:30 a.m. with your mind working overtime about all the possibilities in life? My approach this morning was to fire up the espresso machine, have a double shot, and then continue with the Lefson resistor adventure! I listened again this morning to the 10R Lefson Premium silver/carbon resistor in... Read More »

If you read my previous Lefson post about the Lefson resistors provided to me by Xavier Lefebvre, who owns and operates Lefson, you know that I am gearing up to write about the three lines of custom and hand-crafted Lefson resistors for Positive Feedback. I asked Xavier if he would tell us a little bit about himself... Read More »

It's always wonderful to hear from Yazaki-san, and he's always got some great ideas for audio adventures! A week or so ago Yazaki-san told me: Dear Jeff-san, I have a plan to send you a pair of resistors and also a pair of reproduction WE18GA wire for power cables. The resistors are prepared for the...

After getting up this fine Saturday morning, while drinking a couple cups of my favorite coffee from Stumptown Coffee Roasters, I set about pulling off the bottom of my vintage vacuum tube McIntosh MX110Z tuner-preamplifier so I could do a little surgery on it. I had two things I wanted to do while under the bonnet, the... Read More »

I had a nice day of music listening yesterday afternoon with Leo, Pete, and Ron, as we did some listening comparisons with the Altec A5 Voice of the Theatre loudspeakers and their Hiraga-san inspired crossovers. The Jean Hiraga designed crossovers are about as perfect a match to the Altec A5 Voice of the Theatre loudspeakers as one could hope for,... Read More »

I've been thinking a lot about tone lately, and in particular, vintage tone. If you look up 'tone' in the dictionary you'll see half a dozen definitions for it, but what I'm referring to when I say 'tone' is more in line with what musician's mean when they say 'tone', and what I think music lovers & audio hobbyists mostly...

I am delighted to say that the vintage Altec-Lansing A5 Voice of the Theatre Project is now moving forward again! In the first phase of the project I commissioned Gary Fischer to restore a vintage pair of Altec-Lansing A5 Voice of the Theatre loudspeakers, which I described in three parts: Part 1, Part 2, and Part 3....
