as for the moment i am first looking into IC. When i have found the IC that works as i hope, i might dig more into PC's.
However, as it is now, i have noticed the Signalcable Magical dig, is quite good for amp. Though, i would rather have the Silver Ref PC (ofcourse).
The Silver Ref IC, is very good. It's downside in comapare to the Ref IC, is the bass and bass control. I don't feel the Ref IC is worth the suggested price, as a used buy. The Silver Ref has a more wide presentation on the top, slightly more revealing and open.
If the bass and extension and control was on par with the Ref IC. The Silver Ref would be a slayer. I feel and believe, the network cables are doing something here. However, i still wonder why i see no IC's made especially for class d amps. It amazes me. These amps seems more in need of true rfi rejection. Aswell as i believe that a larger diameter PC do more in terms of richness and fullness aswell as bass extension. I tried two no-name PC's, they are about the same. One is larger in diameter than the other. The larger seems an improvement all over.
As i've been working with a project for my speakers, mainly a control over bassreflex ports. This was not something that could be bought. So, i did some prototypes. Now i have had some units laser cut to fit the ports/gates, aswell as i have ongoing, machined cones done. This is to make a control of the output of the ports. My ports are vented at upper and lower bass. These prototypes has proved giving more nuance and improving impact. Testing with totally open ports, closed and one port closed. Aswell as my own prototypes, makes it clear there is a good margin for change to the better. In this project, i noticed significant changes when trying IC's. I have been slightly obsessed lately. As i see it, at my speakers, the gates/ ports, do as much as passive drivers. It is difficult to explain this. But it is very audible. When an IC proves as much improvement in terms of bass extension and control as it does on the speaker as of original, it proves even more so with the protypes. I believe the ready made units will do slightly better. So, i can't wait to get hands on a better IC and PC. Ofcourse, money is a problem. Otherwise i've tried some IC's and PC's i really believe would make a drastic change. I have also found special made weights, to palce on to my speakers. These absorb chassias resonances and turn them into heat. I can't wait to get them. I have also got decoupling feets after this weight. So i expect vibrations to not goet down in the floor and back into chassis. Now resonances will go upwards, into these units that is on top. This also will make bass more nuanced and clear. It also affects midrange and tweeter. Many small changes in a system, makes a great deal in the end result. I find it very rewarding, doing some improvements not costing as much as a Transparent IC. The worst thing is, that i know, the more improvements i can make, the better, a better IC and PC will also improve. Dah... how smart;)
