Duelund Capacitors??


Does anyone know what the sonic differences are between the copper foil capacitors and the aluminum foil capacitors.
The copper caps are twice the price. are you getting twice the sonic benefit by using copper over aluminum foil caps?

"One other thing to note, and this is directly from Tony - to get the 'sound' of a capacitor, you only need 10-20% of the total value to be the 'good' cap. Example - you need a 5 uF cap for a HPF. Use a 4.5 uF Clarity Cap and a 0.5 uF VSF copper, and it's almost identical to the sound of a 5 uF VSF, and you've spent significantly less."

For output coupling, should the 2 caps as above be used in series or parallel?

Thanks.
Steven, the bypass high-quality cap is connected in paralell with the larger, less expensive cap.
Their values add. In the example above, 4.5 uF + .5 uF = 5 uF. The combo replaces a 5 uF cap in the crossover.
Thank you Casouza :)

Out of curiousity, if they were connected in series, what would that do to the total value?

Thanks,

Steve
Steve, the resulting value is defined by the formula C1 x C2/C1+C2 , in this case about 0.45uf. BTW this is the same formula for resistors in parallel.
Hi Atmasphere,

Great, thank you for the education, I should read more about these things!
