Capacitor log Mundorf Silver in Oil


I wished I could find a log with information on caps. I have found many saying tremendous improvement etc. but not a detailed account of what the changes have been. I have had the same speakers for many years so am very familiar with them. (25+ years) The speakers are a set of Klipsch Lascala's. They have Alnico magnets in the mids and ceramic woofers and tweeters. The front end is Linn LP12 and Linn pre amp and amp. The speaker wire is 12 gauge and new wire.

I LOVE these speakers around 1 year ago they started to sound like garbage. As many have said they are VERY sensitive to the components before them. They are also showing what I think is the effect of worn out caps.

There are many out here on these boards I know of that are using the Klipsch (heritage) with cheaper Japanese electronics because the speakers are cheap! (for what they can do) One thing I would recommend is give these speakers the best quality musical sources you can afford. There is a LOT to get out of these speakers. My other speakers are Linn speakers at around 4k new with Linn tri-wire (I think about 1k for that) and the Klipsch DESTROY them in my mind. If you like "live feel" there is nothing like them. In fact it shocks me how little speakers have improved in 30 years (or 60 years in the Khorns instance)

In fact I question Linn's theory (that they have proved many times) that the source is the most important in the Hi-Fi chain. Linn's theory is top notch source with lessor rest of gear including speakers trumps expensive speakers with lessor source. I think is right if all things are equal but Klipsch heritage are NOT equal! They make a sound and feel that most either LOVE or hate. (I am in the LOVE camp and other speakers are boring to me)

So here goes and I hope this helps guys looking at caps in the future. Keep in mind Klipsch (heritage Khorns Belle's and Lascala's especially) are likely to show the effects of crossover changes more then most.

1 The caps are 30 years old and
2 the speakers being horn driven make changes 10x times more apparent.

Someone once told me find speakers and components you like THEN start to tweak if needed. Don't tweak something you not in love with. Makes sense to me.

So sound
Record is Let it Be (Beatles)
The voices are hard almost sounds like a worn out stylus.
Treble is very hard. I Me Mine has hard sounding guitars. Symbals sound awful. Everything has a digital vs. analog comparison x50! Paul's voice not as bad as John's and George's. Voices will crack.

different lp
Trumpets sound awful. Tambourine terrible. Bass is not great seems shy (compared to normal) but the bad caps draw soooooo much attention to the broken up mid range and hard highs that are not bright if anything it seems the highs are not working up to snuff. I have went many times to speaker to make sure tweeters are even working.

All in all they sound like crap except these Klipsch have such fantastic dynamics that even when not right they are exciting!

Makes me wonder about the people who do not like them if they are hearing worn out caps and cheap electronics? Then I can see why they do not like them! If I did not know better from 25+ years of ownership that would make sense.

For the new crossover I have chosen Mundorf Silver in Oil from what I have read and can afford. I want a warm not overly detailed sound as Klipsch already has lots of detail and does not need to be "livened up" they need lush smooth sounding caps. Hope I have made the right choice?

When the crossover is in I will do a initial impression on same lp's. Right now it goes from really bad (on what may be worn vinyl) to not as bad but NOT great on great vinyl. (I know the quality of the vinyl because tested on other speakers Linn)

The new caps are Mundorf Silver in Oil and new copper foil inductors are coming. I will at the same time be rewiring the speakers to 12 guage from the lamp cord that PWK put in. PWK was a master at getting very good sound often with crap by today's standards components.

The choice of speakers would be a toss up now depending on what I am listening to. Klipsch vastly more dynamic but if the breaking up of the sound becomes to much to effect enjoyment the Linn would be a better choice on that Lp. If I could I would switch a button back and forth between speakers depending on song and how bad the break-up sound was bothering me.

If so that makes the RS very different than CAST an oil cap clearly.

I wish Duelund would chime in here and clear some air and as to why the switch?
To be honest I am becoming less enamored with Duelund. With Jupiter who needs the crazy expense and I am hearing of leaky CAST caps regularly from folks. Duelund is very good about replacing leaky caps for free and that is a good thing.

I am also confused as to what a CAST cap is! The .22uf one in my work room, cut in half, has no paper in it and has layer after layer of thin plastic or Mylar stuff. No joke guys.

I sense the lower voltage crossover CAST caps, the ones that are wide and flatter, are the most special ones.

I just purchased some Jupiter copper foil caps for speakers. The new 100 volt caps. I will report back to all once they are in.

Thus far the high voltage Jupiter caps have bested the high voltage CAST caps in the electronics I have used. We will see how good the 100 volt crossover caps are soon. The 3.3 uf caps cost $200 each and are not cheap, but they are still priced well under CAST. They go on sale for 20% off at Parts C and Sonic Craft reducing the cost to $160 each.
I will need to look, the Parts Connextion site says its a PIO as well as reviews and website....
From the Duelund site....page on CAST capacitors. Yes mine do say CAST on them....

CAST
World’s best capacitor…

The Duelund CAST Capacitor is our no holds barred flagship capacitor.

The construction builds on the foundation of our Virtual Stack Foil design but does so with the addition of a proprietary WPIO dielectricum which necessitates several days of impregnation under high pressure.

This creates a form with incredible damping properties giving a mechanical stability hitherto unheard of.

On top of this casting process, a ring of hard pressed paper strengthens the damping properties of the design helping music flow effortlessly.

The Duelund CAST capacitor is available for speaker use and as the CAST 630v for DC-applications for size considerations this cap is cylindrical.

Available as pure copper or copper/silver.

Standard sizes 0.001 uF – 50 uF other values available on request.

The Duelund CAST Capacitor is considered the world’s best capacitor:
