Straight to the point. Just backed home tonight from a crazy traffic, then it was a great moment to payback! Let’s solder the new Duelund CAST Resistor. You can see brief information about Duelund CAST Resistor here and  my DIY speaker here.

I decided to switch back to Auricap few months ago (from a set of Siemens NOS capacitors). I eventually realized that using too many capacitors in parallel may reduce some factor, like imaging and separation. The tonal should be similar, but some other factors mentioned before might be altered or reduced.

Okay then, let’s change the old Sfernice RLP10NI to Duelund CAST Resistor.

After around 15 minutes soldering, I completely finished the modification.

My first initial impression. The music was more solid, good depth and separation, but never got it too harsh. I also felt that it was even more relax in terms of musical pronounciation. If I felt that the Sfernice still has some “stiff” characteristic, then the CAST resistor absolutely very relax, even just powered on for few hours. To be honest, the role of this resistor is very important since the location is on the front of the signal path.

I will provide more experience after several hours. We sill have some Norah Jones, some Chen Lily, some Ingram Washington, some John Campbell, or also some Tsuyoshi Yamamoto.

A pair of Duelund CAST is enough to rob your wallet. How about two pairs? Well, sometime money is not an object – when you are pursuing the ultimate sound. No sky is high enough

I welcome, two pairs of Duelund CAST Capacitor installed on 6J5-RE604-RS241 Amplifier. The installation process was done just before end of last year (31th December 2009, night!). And well, I saw many fireworks when driving home (around 00:15). Happy New Year first!

Not really published on the market (at least not well spotted around big online webstore), but I manage to get a pair of it.

This is the CAST version of the Duelund Resistor. Well, for the Capacitor, the CAST definitely better (less ringing, so quiet, dynamic). How about this Resistor? Not sure though, plan to test it somewhere. Picture below is the 5W version.
