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!

I was playing with my Rigol Oscilloscope to measure my laptop power output. The sound card was Realtek ALC660.

I played a 1 kHz sine wave with a software and measure the output. Since this was not an isolated environment (I have some application running on the background), so the frequency measured was not completely locked at 1 kHz.

On my typical daily usage, the output measured at 102 mV.

After completing the construction of my Duelund Interconnect 2.0 Rev2 here, I decided to do some short comparison. My friend has Duelund Interconnect 1.0 Rev1. I think this gonna be a nice comparison!

Direct to the stage, we have some equipment on hand, like floorstander 3-way speakers, CEC CD Player, Marantz CD4000 fully modified with tube output stage, Hybrid F4 power amplifier, Aikido 6N1P-6N6P powered with Duelund CAST Ag/RGN1054 Mesh Rectifier, and also #26 Pre-Amp powered with Jensen Paper Tube and AZ1 Mesh Rectifier.

Without any further ado, let’s go to review those cables.

Last week, we have a local DIY audio gathering at Bintaro (Indonesia). I took some photo, hope these could inspire us (DIY) more in the future. Sorry I didn’t “remember” all the equipments in detail. So most likely, you will enjoy the photos without caption.

The overall look of the stage, used for the testing.

I designed a simple SRPP PCB for my own project. A special thanks to my friend, Mr. ATP who helped to process the PCB fabrication.

Well, later these days, I just feel more comfortable with PCB rather than point-to-point wiring. It’s nothing special, just an ordinary SRPP design.
