It’s been a while since my last capacitor comparison review was done. Not much changes actually (not much new ‘interesting’ products also I think). But I was quite tempted to try the Alexander series from Duelund. The reason was simple, it’s quite affordable but having Duelund popularity on it. We’ll see if it’s worth to try.

As usual, I put one of my favorite ‘affordable’ reference capacitor, the Jensen Paper Tube and the ‘premium’ reference capacitor, the Duelund CAST Cu. I kept my ‘ultimate’ reference capacitor, the Duelund CAST Ag, as this was a different beast.

It’s been a long since I promised to write this article: A comparison between Audio Note Copper Foil Mylar-in-Oil, Jensen Copper Foil Paper Tube, and Jensen Copper Foil Copper Tube. Some of my blog readers already email-ed me to ask about this. Due to my main job, I couldn’t finish this article immediately. So just this weekend, I spend few hours to have a listening session on this three capacitors.

Below is the test bed. A little bit awkward, but at least it works flawlessly!

Just what I’ve promised before, finally today I do the most awaited Capacitors Battle. Actually the “real battle” will be done within next few days. Let’s say, this is as first impression to “hear” how good they would sound

I use ELMA Switch (2 poles, 6 positions). Click here for details. The connection in details also explained there.

Here is the appearance of my jig. It’s an Aikido Pre-Amplifier. Powered with 6N1P tube in front connected to 6N6P tube as buffer stage. Rectifier is RGN 1054. The capacitor used as output coupling. Each channel has it’s own ELMA Switch. Please remember the selection is made in “perfect” mode (read here for details). Oh, I use empty CD holder as base for my ELMA

Still remember the Extreme Capacitor Battle article? Well, it’s not done yet, but we are very close on it. The break-in session has reached around 180++ hours. I can feel the characteristic from each capacitor.

To simplify (and easier) comparison session, I have prepared two ELMA switch (2 poles, 6 positions). You can see the photo below.

You might ask, why do I need two pieces of this ELMA? One should be sufficient, right? Keep reading. As you may also notice that I have a “bad habit” as a perfectionist, so this is still related with it
