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.

Again I have no idea how you can evaluate each component like this in MONO, yes you will get FAR better effect with every cap and inductor in stereo pairs on any speaker. That’s why to me a lot of this was a throw away thread, I am sorry.

Until you can give a real evaluation with BOTH speakers set up correctly, running equal parts to hear the real deal in soundstage etc… Not one speaker running with one supposed better part and just shifting your balance knob on a to the other speaker and saying OH I can hear one is better than the other, we don't have much to go on, because in this case not all things are equal from you are saying.

So yes I suggest if your serious about one part, order its companion and then put it in to the the real test running as it should on both sides of the room and see what comes together.

Its actually kinda strange many have fed the beast on this thread as it stands not reading or realizing you are evaluating a critical soundstage and passive component on one channel at a time… You asked the question so I say YES order it so you can hear the entire balanced soundstage of caps and inductors!

I don't believe any of the Tony Gee or whoevers reviews you refer to were doing this in a mono test on stereo speakers, I am sure they had a Pair… Beyond that believe me when I say even the more "Ruff around the Edges" caps or inductors you are stating don't do justice will actually sound smoother when you hear equal signals on both sides at once opposed to one sided mono killing the whole thing off in the first place.

I would like to hear back from Duelund on the thoughts of evaluating their caps and inductors in mono for speaker pairs?

Good luck

I made a mistake this process would not even be really "Mono" but half of a signal! Half stereo missing many things on recordings that would be on the other channel. So this makes it even worse to evaluate stereo recordings as you are if I understand the way you are trying to come to these conclusions?

Acoustics, by the way this plays a HUGE part in what your hearing. First off running one speaker in one corner at time, lets imagine your cranking your stereo and a channel goes out, blows whatever.. What does this sound like? CRAP regardless how good the components used are! Fact is your missing now the Center image in the room, and yes DISTORTION goes up substantially because you hear all the artifacts of the room on that side no longer being integrated and even cancelled by the other side of the room…

Also Recordings for example, I can play one that is very GUITAR heavy to the left channel lets say, cut that speaker off and the right losses a bunch of the info in the right. Vocals foget it, Midrange forget that too as you cannot have a warm centered voice and sound stage in the room anymore because your missing a channel. Bass as well now you are OVERLOADING one side and it sounds like Crap.

So again I would like to know how this is an accurate style at all for really evaluating true hi end stereo 2 channel? Also just a note, I believe you are evaluation CORNER horns? This is even worse, they are only echoing out of one corner or the other, No breathing room as they are smack dead in your corners, so yes you basically would have a boom box blasting at you from one side of the room evaluating one Crossover at a time vs. Stereo.

So please you have spent the money, its time to get the Pairs to make your system work correctly and you might find that all this back and forth is not necessary and you will get a great sound already. I understand the stuff is expensive, but you chose to get into this in the first place, so its best to do it right at this point, doing yourself a huge favor getting a true balanced sound all together, and no doubt 2 channels with a "Sonicap" will sound better than ONE with a duelund :-)

Yes you are correct. I just could not afford to do what Jimmy has done. I often reverse the parts and use several amps and reverse tubes etc. So Yes not exact but often there can be such a huge change it is not hard to hear at all.

Speaking of a huge change as much as I have struggled with the Jensen vs. vintage Vishay I am having no such trouble with the inductors.

The Deulund is MUCH smoother. The midrange much better. The North Creek has a starker and harder sound. The North Creek like Irish said may dig deeper? I am not sure yet? I had mentioned a long time ago every time I put in a Duelund part in seems to make all sources sound better. They make your best sound better and your worst. To me this makes them unique. The WPIO inductor is no exception.

This is a lush sounding inductor.

I will be comparing over next few days but if the initial impression is correct (and I think it is) I have ordered my last new non Duelund part as I simply am not interest anymore in anything else. I do want to see how this inductor compares to vintage though. So far better in every way. (from memory)

The inductor is a very overlooked part in my mind.

SET had posted on his thread that his North Creek is much better than a Solen inductor. For sure I can imagine this. I have never heard a Solen but there is no way to deal with resonance in this inductor. Just loose wire with twist ties.

The North Creek uses very hard wire and bakes to one another to one hard chunk of copper. This goes part way on resonance reduction.

The Duelund WPIO is a fairly hard chunk of all natural material of paper and oil and in which the wires do not touch each other.

What does this mean. The NC resonates and gives a blurry background in comparison. The Deulund sounds darker but more realistic. That high freq resonance that the Clarity White Paper talks about is very real.

The Deulund also sounds more natural in tone. Is that the Silk oil I do not know? I expect so. Nevertheless this is one fine sounding inductor. I can only imagine what a CAT sounds like. I would expect the same as in the caps even less noise.
