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.

I read once on the net a guy joking about not taking apart a speaker because the inside (crossover) contained dragons.

In the beginning of this tests I kept two systems one a former top of the line Linn with all Linn gear right from the cartridge to pre amp amps IC's and speaker wire all Linn recomended. I thought even if they were not the best parts they should work well together?

It was good to have a reference. All the Duelund parts were tested with SS, tube amps, digital and analog to make sure the results were consistent.

I have since rid all of the linn gear except sources. So do not have two complete systems to test against each other. Only tube amps. It is nice to have a reference even if you are not keeping it.

George at North Creek said the Air core will make the Steel laminate core sound broken and he is right. I can not believe how different the two speakers sound. Even though he is right there is something not right about the big air core. Even though the old inductor sounds broken somehow it sounds better?

Both inductors sound as they look, oddly enough. The vintage constricted flow, dead with no resonance. The big NC much louder open but with a hard etched sound, which it is a big hard chunk of copper.

Resonance and horns do not go well together. I can see why the CAST inductor was made for Burt's horn speakers.

Horns can sound really good and really bad depending on so many things and are very sensitive. I do not mean NC are not a good inductor either just not suited to horns. (IMO)

Its called "Hearing whats really upstream now"
I can tell you this, I just purchased the 8 gauge inductors from northcreek, they are the exact opposite results.. I am running Class A amps directly into them, excellent sound, very smooth, very warm... 125 db deathmetal sounds as smooth as butter!

So you have many other things to look at once again vs. one part you get hung up on. Keep matching you will find something at some point I would assume. But its not due to an inductor being inferior, its because many other things are. You can discount everything everybody says until you hear it yourself as many times as you like, just remember many have put a lot on the table for you to ponder. And by the way thought you had the NC inductor on your woofer? Not the horns?

Mine are now on the woofers and my horns are on ERSE 14 gauge perfect lays with Perfect sound. I have replaced Alpha core Ribbons just out of curiosity. However the Ribbons are really just as good, but different, they might be a little warmer but nowhere near as low of distortion as exhibited by the 8 gauge north creeks, they are virtually impossible of an inductor to saturate.

Just ordered a Duelund WPIO inductor.

I just have to hear the difference. I would love the CAST only the $$$ are stopping me. The DCR is almost and exact match to original so no changes there.

I hated my CD player until I got tubes and Duelund caps. I thought the CD player was junk. I may even get rid of the LP12? Not sure on that yet.

So far all Duelund products have been fantastic.

Takes 3 or 4 weeks to get here. I have come this far might as well go all the way.

I hope Duelund starts to make Autoformers as that would be the last non Duelund part in the crossover. (except tweeter resonance trap that is in parallel)

I would then be all natural all plastic free in the crossover. Removing the speaker wire from plastic would be next cheapest thing to do.

Undertow, if you have a cap in your LF, what brand is it?
