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 of you rallying around me, encouraging me, and helping with donations to get things up & running again, Jeff's Place is now secure, and will hopefully keep on going and growing!

Thank you for your encouragement and support, I really, really, appreciate it.

As a way of saying "Thank you!"  I have installed a new permanent page titled Friends of Jeff's Place - Thank you! to acknowledge you for your kindness and support.

I'll continue to add donor names to the list as donations to support Jeff's Place come in now, and in the future.

I must say it was very heartwarming to have you rally around me and encourage me! Thank you! 🙂

Positive Feedback Review: "Lefson: French High-End Analog Audio Devices - The Lefson Resistor"

I finished the Lefson resistor review yesterday for Positive Feedback, and it is now in Editors Dave and David's hands for review, approval, and publication.

The Lefson Premium, Supra, and Ultra resistors in the Altec A5 project crossovers.

In case you're wondering, the Lefson's pretty much slapped down the lovely sounding Ohmite Brown Devil resistors, it was no contest.

Lefson Resistors with LP for scale!

A number of revelations occurred to me listening to the Lefson resistors, and the differing approaches taken by Xavier in the design, construction, and materials choices for each of the three models (Premium, Supra, Ultra) made for a significant difference in each model's overall sonics & musicality - vive la différence!

The magnitude of that difference caught me by surprise, as each of the Lefson resistors utilize a combination of pure silver leads, carbon resistive elements, silver end plates, that are all potted in plastic cases, that utilize a variation on a theme to come up with rather unique results.

Lefson resistors! Top to bottom, Premium, Supra, and Ultra.

The Lefson resistors are finely crafted, beautiful to look at, and a joy to use!

They do take some preplanning though, as their large size can make them tricky to incorporate into a circuit board, as you can see from the photos above.

I'm of the opinion that the Lefson Ultra resistor, in particular, is the finest resistor I have ever heard in a crossover application.

The Lefson Ultra may very well be the best resistor for crossover use in the world.

How did I come to that conclusion?

Lefson Ultra Resistors. The best in the world? From what I'm hearing that's very likely the case.

The review I just finished is the obvious answer, at least as far as the lovely sounding Ohmite Brown Devil resistors are concerned, as well as my 'off the grid' comparisons with the highly regarded Path Audio resistors that I also like and respect, but didn't write about in the review.

So far nothing has come close to the Lefson Ultra, it is simply in a class of it's own, although the Lefson Supra is knocking at its door.

As soon as the review at Positive Feedback goes live (today maybe?), I'll post and update with a link to the review.

Duelund DCA20GA Tinned-Copper Tone-Wire

The shielded Duelund DCA20GA tinned-copper interconnects have now received a little over 100 hours conditioning time on my Cable Cooker, and have been getting plenty of play-time from in the position from my SUTs to the MX110Z tuner-preamplifier.

I have some interesting results to report, both in comparison to the shielded Duelund DCA16GA and the shielded Duelund pure silver foil interconnects.

Shielded DCA20GA tinned-copper tone-wire interconnects.

The Duelund DCA16GA & DCA20GA series of cables have really been a lot of fun to experiment with and write about, and it's rare when you come across anything that has such a high level of performance and is such an incredible value at the same time.

I am really intrigued by Vlad's comment about combining DCA16GA & DCA20GA in a pair of speaker cables that feeds both the high & low-frequency sections of the crossover, so I may have to give that a try.

As a result of Vlad's comment, I'm also curious what a pair of interconnects would sound like with DCA20GA on the pins, and DCA16GA on the returns - could be very interesting!

The DCA speaker cables I'm using now with very nice results are a bi-wire pair, with DCA20GA for the high-frequency connection, and DCA16GA for the low-frequency connection. I like it!

I also want to try DCA20GA as wiring in the low-frequency circuits of the crossovers, as well as speaker cables, just to hear what happens!

When I sort through the various DCA permutations I'll rewire my Westminster's internally with Duelund DCA as well.

I don't know if I'll get time today or not, but I'd like to tell you more about my results with the shielded Duelund DCA20GA interconnects I made, so stay tuned!

Here's what's coming in the review queue for my Positive Feedback articles:

• The Duelund DCA20GA tinned-copper tone-wire. This is going to take me a little while to do because it involves a lot of rewiring work with interconnects, speaker cables, crossover wiring, and internal wiring of my Westminster's.

• The Acoustic Revive RAS-14 TripleC NCF Power Conditioner, the Acoustic Revive Power Reference TripleC NCF AC power cords, and the Acoustic Revive RPT-6 Absolute NCF power distributor.

Ok, that's it for now, but as you can see, there's lots of good stuff coming here at Jeff's Place, and I'll be giving you the unvarnished inside insights for all of it as I proceed!

As always, thanks for stopping by, and may the tone be with you!
