January 19, 201412 yr Old article but generally polyprops, foil or pio have the biggest effect in crossovers.
January 19, 201412 yr At least the dude tried........ You got that right. Jesus, that had to take some time. He definitely has conviction. But Justin is right, sample size of one done casually? It makes for an interesting read though. I never knew of some of those types.
January 19, 201412 yr You got that right. Jesus, that had to take some time. He definitely has conviction. Unless he made the whole thing up to drive traffic to his site... Wonder if there is any correlation between the prices of the caps and their rating. Edited January 19, 201412 yr by crappyjones123
January 19, 201412 yr price the deulund and you will have your answer http://www.partsconnexion.com/capacitor_film_duelund_vsf_speaker.html http://www.partsconnexion.com/capacitor_film_duelund_pio_electonic.html Group buy anyone?

January 20, 201412 yr Capacitor upgrades are kind of like tube rolling and cable swaps. There are differences but they are usually small. Most of the differences are more the result of the type of cap ( PIO, polyprop, teflon, etc.) than price or brand difference. The biggest improvements come with the first jump off the bottom. You can usually easily hear the difference between a $1.00 coupling cap and a $10.00 cap of the same type. You'll need to strain to tell the difference between a $10.00 and a $100.00 cap. For a cheap comparison of different types, try the different Russian military surplus types. The teflons and the K40 PIO's are excellent. Bottom line is serious money is better spent elsewhere.That said, I did find the above review interesting and useful in a subjective sense. I've used a number of the capacitors mentioned, and the author's opinions roughly correspond to my own.Power supply caps, at least in single-ended tube amps, seem to make more of a difference. Motor-run PIO's are a definite sonic upgrade to traditional electrolytics. Same story with cathode bypass caps.All caps are necessary evils. In the end, if you can do it, the best cap is no cap.
January 20, 201412 yr Or you could measure the capacitors... http://diyaudioprojects.com/mirror/members.aol.com/sbench102/caps.html Signal path capacitors don't really matter to me once I get to the $5-$8 point since I'm not using high-end super resolving headphones. As for power supply caps, going to oil filled motor run caps was a significant upgrade, even on my push-pull amp. So was getting rid of cathode bypass caps & resistors and replacing them with LEDs. I took both steps around 10 years ago and never looked back.
January 20, 201412 yr So was getting rid of cathode bypass caps & resistors and replacing them with LEDs. [top-down-arm-chair-designer] How can you claim to have a tube amp when you have stooped so low as to use a Cathode LED? I bet your going to try to tell me that you use SS CCS's next. Whats the world coming to? [lolerskates]

But check it out, no capacitors in the signal path!
